Failure to Feed in Glock 27 - please help

[PackinMama]

I just recently purchased a gently used Glock 27. I was told it had less than 50 rounds fired through it and it looks brand new. It came with two factory Glock magazines, one with a pearce +1 extension and one with a +2. I fired 80 rounds through it so far. During my shooting session today, I had a failure to feed twice, one in each magazine.....and with two different brands of cheap fmj 180 gr. bullets. The first time it happened, it was in the mag with the +2 extension and it was the last bullet.....the slide locked back like it was empty, but it had one more bullet in the mag......I manually brought the slide back and then the bullet fed into the chamber. The second time it happened it was in the +1 mag.....and it was my last three rounds that I loaded into it.......the slide was locked back, I put the mag in and pressed the button (please forgive me for not knowing the exact word for this "button" :blush:) for the slide to go forward and it didn't go....so once again I manually brought the slide back and it then fed into the chamber.

So, can any of you Glock experts on here tell me what might be wrong? And for all you Glock haters out there, please don't tell me I shouldn't have bought a Glock ;)

Very odd. Glocks are generally very reliable. My problems with them are in other areas.

Since you don't seem to have problems with limp-wristing, I'd have to guess it has something to do with the extension magazines?

Maybe I've mis-read your post, but that is my guess.

[FlyboyLDB]

If you have the original plates that go on the mags I would re-install them. Then give it a try a see what happens. I have a 27 with a pinkie extension - no +1 or +2. I suspect this is where your issue is. I have fed my 27 everything from very cheap stuff to the very good stuff. I have never had a jam. On my 23 I had installed the +2 extension and it did jam or ftf a few times - I had several mags, so I just set this one aside.

[tjbert47]

I carry a 27 24/7 shoot it at the range regularly. The only problem I have had with it was with the extended magazines. Replaced them and no farther problems.

Hmmmmm......I just placed an order today with LWD for two mags with pearce +1 extensions......damn:( I really like the extra place to put your pinky......do you guys think the pearce extensions without the extra capacity would be ok?

[EasilyObsessed]

When I had my Glock 27 it functioned flawlessly for around 500rds using Pearce +1 extension.

[Marswolf]

I think one question is why you need expansion mags? Glock's provide far more than necessary rounds in their normal configurations. And those rounds are very reliable.

[PackinMama]

Like I said.....I really like the extra groove to put my pinky finger....but if these extensions are going to cause failure to feeds.....I can live without them. I've shot over 10,000 rounds through a first generation Glock 17, and about 5000 through my Glock 23 with not one failure of any kind in either gun. These two failure to feeds today in my new G27 really have me bummed out. I want to start carrying this weapon as my primary carry gun.....but I need to be able to rely on it.

[Urse]

It sounds like you primarily are looking for the extra grip area. I have 3 or 4 of the Pearce grip extension that just replace the factory baseplate and do not add any capacity. I never had a problem with them I just never liked them. PM me your address and I will mail them to you if you want them.

[Guns&Dobes]

Hi Tabby, I am glad to find out the extensions may cause a problem since I was thinking of getting them for my G26. I stopped at the gun store today to check on them but they were out but while I was there I did buy one of the Pearce grip extensions and it works beautifully, I need to get one more for the other magazine but I think you would be happy going that way.

[PackinMama]

Diane, I already ordered two new magazines and asked them to install the +1 extensions on them......too late to change my order now, so I guess I will try out the new ones when they arrive and see how they work. I talked to a Glock technical rep today before I ordered them and he recommended the pearce brand to me. Urse said he is going to mail me his pearce extensions with no extra capacity....so I think I will install them on the two mags that I had problems with today and see how they work. I was reading on the GlockTalk forum and I didn't find anyone on there that had problems with the plus capacity extensions.....so I don't know :confused: The new mags I ordered are fully metal lined and the ones that came with my gun are not....maybe there will be a difference with that :shrug: Something you would probably like for your G26 that I also ordered today is a Hogue Jr. grip. I have a Hogue grip on my G23 and I love the it.....the feel is really nice and it helps cushion the recoil too. You should check out Lonewolfdist.com.....they have them on there....along with a lot of other Glock accessories.

Failure to feed could be caused by the following.
Weak magazine spring
Limp wristing
magazine not fully seated in mag well
Off the top of my head thats about all I can think of.

It sounds like limp wristing. However, I will be sending the extensions first of the week.

[GhostDog]

It's a pretty small gun w/ snappy recoil. Make sure you're not bumping the slide lock when you shoot.

[Guns&Dobes]

Tabby, when you get it figured out let me know, the extension that I bought wasn't the one to hold extra bullets, it is just there for my pinkie :D

Hopefully it will do better with the new extensions, I want you to love your baby as much as I love mine. :D

[kdgreen23]

It is the extra capacity mags causing the ftf. I had the Exact problem so I replaced both of the mag plates with the pierce pinky extension with flat
plate and wallah! No more problems. My g27 would shoot rocks if they would
fire.

[PackinMama]

I heard that there is sometimes a problem with the mag followers.....the numbers on mine are 5's......on Glocktalk many people say you should replace them with #8's. Anyone know anything about this?

[jackdog]

Had a mag with # 5 on it, and it had some proplems. Replaced it and every thing was fine.

[Glockster27]

I have extensions ( 0 to +2 Pierce and Glock OEM) installed on all 9 magazines for the G27 and have NEVER had any problems with them. :) It could either be limp wristing, weak magazine springs or bad followers.

Everyone that seems to have this problem automatically blames the extensions for the problem. I must be the 1 out of 1 million that doesn't have this problem. Go figure!!

[YANKEE2500]

Pearce grip extension is the way to go, have them on my g-26. John

[deerslayer]

The suspect mags need to be disassembled and inspected, since you don't know who installed the grip extensions. Make sure there is a mag insert--the small, flat black piece that goes between the spring and the baseplate. Some people leave these out when installing grip extenders. It shouldn't matter whether the mag ext. is a +0, +1, or +2--they should all run fine if they are Pierce. Also, as mentioned above, the mag follower could be an issue as well.

[Todd@CIS]

Unless I'm reading your post wrong, you're have problems with premature "lock-back."

Three things cause this...
1. Thumb hitting the Slide Stop Lever during recoil (as GhostDog mentioned and the most common cause).
2. Broken Slide Stop Lever.
3. Bad Magazine Followers or bad interaction between the Slide Stop Lever, Follower and/or bullets.

Your mag extentions would not contribute to your "lock-back" problem...if anything, they could contribute to "failure-to-lock-back" or "failure-to-feed."

[PackinMama]

Ok, here's the latest on this issue. I took my G27 to Coal Creek Armory in Knoxville today and had it cleaned and inspected by a Glock Armorer. He said the gun looked great with no problems at all. He did not seem to think the magazines, extensions, or the mag followers were the issue, and he said the mag springs were fine. He said what several of you have said already......probably either limp wristing or my thumb accidentally hitting/bumping the slide stop lever. He also said that when I put in a fresh magazine with the slide locked back, that I shouldn't press the slide stop lever to chamber the round......I should "slingshot" the slide by pulling back all the way and letting go. I have always used the previous method in both my Glock 17 and my Glock 23 with no problems ever.......but maybe with this smaller gun it's different? :shrug: I brought up the question of whether to replace the mag followers and he said he thought they were fine. So, I think I will try (and hope I don't screw up :eek:) to disassemble the mags to see if that smaller baseplate is in there...and clean them while I am at it. Then I will just go put some more rounds through it and see what happens. If I still have a problem, I will wait and try the new mags I ordered and see if that makes a difference. Thanks to everyone for the input! :)

Try your 23 mag in the 27 and then you'll know for sure if its the mags or not.

my 33 did this very same thing a time or two right when i first bought it. my problem was from limp wristing the weapon. i changed my grip and all is good. all 4 of my mags have extentions. 2 of them have hte +1 and the 2 new ones i just bought online last week have the +2 that i had to install myself. that took about a minute to do.

the only other quirk i have had with the 33 was the last time i was out shooting, me and the Gf were taking 2 clip turns. i have been working on her with her grip, as the 33 is a monster for recoil. she was limmp wristing it so bad that the recoil of the slide actually made the slide lock retention pin slide to the right side inside the weapon, letting the retention part of the spring on the internal side of the run go limp, therefore failing to keep the slide lock down. it would fire a round and lock open. would not close by manually racking, but pressing the slide release , it would close and fire then hang back open. it was the damnest thing and i didnt know what was wrong with it till i got it home and started taking it apart to see what had broken. realigned the spring and reset pin and all has been good.

these smaller glocks are bad for having these little annoying characteristics. a police officer that works with me part time helped me alot with my shooting stance, and since then, my firearm problems related to weapon holding have gone away.

[The Rabbi]

Get a very experienced shooter to fire the gun. If it works fine, then it's you. If not, its probably the magazines.
Other suggestion: get a Model 23, which will provide all the grip you want. The difference in size is not that much.

[Todd@CIS]

PackinMama... except for the "limp-wristing" part, you probably received good advice from Coal Creek Armory.

Limp-wristing does not cause premature "lock-back."
To those that feel it does, please articulate why. I'd love to hear it...

[PackinMama]

I disassembled and checked my mags last night without a problem and all looked good. Rabbi, I already have a G23......I wanted the smaller one to carry. I personally don't feel that I was "limpwristing,"......I have been shooting all types of handguns for a long time.....but I have never shot the subcompact Glocks until now. My hands are not small at all, so the more I think about it.........the first time, I believe when it locked back before the last bullet was fed that I could have accidentally hit the slide stop lever with my thumb. The second time, the slide was locked back and I put a mag with only three rounds in, then I pressed the slide lock lever and it didn't feed.....I had to pull the slide back and let go to get it to feed. The guy at Coal Creek said to not do this and to always use the "slingshot" method. I will try using this method today (if it doesn't rain)....and I'm also going to watch my thumb and "lock" it down with my other thumb when I shoot. Hopefully this will solve the problem. But....I do think I will replace those mag followers.....when I looked at them last night.....I noticed that one stuck up in the front just about a millimeter or so higher than the other one. It looks a little funny to me.

[m4coyote]

I have had functioning problems with the magazine extensions on my Glock 23 as well. I went back to the original floorplates, and all was well from that point on. I have heard very good reviews for the pinky extension for the Glock 27, but only the one that keeps the magazine at stock capacity.

Another possible problem, is that during recoil, you are inadvertently hitting the slid stop with your thumb. I did this when I first started shooting my Glock 23, and the Glock 27 weighs even less, so I would consider this a possibility.

Good Luck!

Yes, you should be ok with the pinkie +0. Has worked fine for me on two mags.

Slide locked back prematurely is rarely a magazine issue... not unless the feed-lips are so bent to one side that the cartridges interact with the slide stop.

If the same thing happens when somebody else shoots the gun, then worry about the gun... if not, then it's your thumb pushing up under the slide stop under recoil.

[PackinMama]

Thank You Urse! :D

Looking back and thinking about what happened......I do think that my thumb probably hit the slide stop the first time it happened....since it happened that time on the last round in the magazine. But......the second time I'm not sure about. The slide was locked back, I inserted a mag with three rounds in it, hit the slide stop lever, and the slide didn't move forward/feed. I pulled it back and let go and it fed. I went out yesterday and shot 50 rds. with no problems at all. I was very aware of my thumb placement and I "slingshoted" the slide when I loaded a new mag. I'm hoping that between watching my thumb and "slingshotting" that I won't have any more problems. 50-100 more flawless rounds and this "baby" will be my new carry gun. :)

Thanks Everyone! :D

[Guns&Dobes]

I am glad you are liking it, I hope it gets through those next 50 to 100 without a hitch so you can feel confident and enjoy the "baby".

I love my "baby" 26 and have been carrying it regulary since I got it.

[mac12]

I also have the glock 26 and have put 408 flawless rounds through it. I was in Houston for a week and found this gun range close to where I was staying. If you can visualize an outdoor range in Texas, that it what it looks like. If I wanted to, I could shoot all day with one gun for $7.00. I have the pearce extensions +1 and didn't have any problems. I will admit that after awhile the trigger became a little uncomfortable, but the little glock performed without a hiccup.

[DWARREN123]

I haven't had any trouble with my G27, mine has the +1 extensions, I get 10 rounds into each mag. It just keeps on running and running with only one FTF in over 600 rounds and that was a reloaded round/dented case.

[PackinMama]

Well......I shot 100 rounds with no problems. I replaced my Pearce extensions with the Glock factory baseplates and I actually like shooting my 27 without the extensions. My pinky curls up nicely under the mag and it feels good, plus it makes the gun more concealable.

I did notice something on all my spent casings that I'm curious about. On the brass rim of the casings on the primer end, there's a nick or cut on the edge of the rim. Does anyone know if this is normal or should I be concerned?

[Marswolf]

I actually like shooting my 27 without the extensions.

That's the way I was when I had a G26 and XD-9 subcompact.

The XD came with an extended mag in addition to the standard one. I tried it and stored it away.

I've never quite figured out why someone would by a subcompact and then buy magazine thingies to turn it into a compact.

[PackinMama]

Yeah, I really didn't think I'd like shooting it that way.....but I was pleasantly surprised when I did. It's much less noticable under my shirt now. I do have two extra mags with +1 extensions that I carry on me for backups.....along with a 13 rd. from my G23 that I keep in my purse :D

So does anyone know about the nicks/cuts in the edge of the brass casing rim? I'd really like to hear from someone on this. I'm no gunsmith by a long shot, but I imagine it's the extractor making these marks......I'd just like to know if it's normal or not.

[Marswolf]

Yeah, it sounds like an extractor mark. I don't know that it hurts anything.
