Apex Tactical Specialties Heavy Duty Striker for FN 509

Recommended Posts

Apex Tactical Specialties has released their Heavy Duty Striker for the FN 509 series of handguns.  Pre-ordering is available as of this writing.

The Apex Heavy Duty Striker for the FN 509, FNS and FNS Compact is a direct drop-in replacement option for customers with FN 509 and FNS series pistols. The striker is machined from a billet of stainless steel and heat treated for enhanced durability. 
 

But Why?

Unfortunately the FN 509 uses an MIM (metal injection molding) striker which has been known to break, particularly with repeated dry-firing.  FN recommends that dry-fire be done with snap caps only and never with an empty chamber, for this reason.  Many other striker fired handguns have no such problems.

Savvy FN 509 owners have been known to source the cast steel striker from FNS model handguns, which is identical albeit not manufactured via MIM, but supply of those can be difficult to find.

This new Apex billet striker should solve both any reliability concerns as well as address sourcing problems of finding FNS strikers.

I’m a Toolmaker. When MIM started being used in guns I was one of the guys (along with many others) that had worked with it that warned MIM is junk. It’s one step above pot metal and is only used because it is cheap to produce high quantity of like parts.

Then I had a catastrophic failure of my SW1911 that rendered it unusable. While I was showing my BIL how the safeties worked on a 1911; I engaged the thumb safety pointed it downrange at a target and pulled the trigger. The weapon fired. The gun would not operate after that. The guys at the range said they had never seen anything like it either. I did not disassemble the gun, but I’m convinced the thumb safety broke. I sent it in. S&W would not answer me about if the safety broke. They only would say the safety was improperly fitted. When I asked them to replace it with a safety that wasn’t MIM; they said they couldn’t, that was all they had. My 1911 has become a range gun, I don’t carry a 1911 much anyway, but until I get this safety change to stainless; I don’t trust it for a self-defense weapon.

Bottom line…as many of us warned, MIM has an application; gun parts is not it.

This is a public service announcement. :)

Kind of off topic, I guess, so please feel free to peel this off.

How does MIM differ (if at all) from casting metal? I'm curious both about the manufacturing process and the strength and appropriate application of the resulting parts.

Thanks!

In casting you are melting metal and pouring or injecting it. In forging you are hammering metal into the parts you want. And in machining you are machining the part you want from a billet or round of solid material. Those parts can then even me heat treated and finished. In MIM the metal is in powder form, binders are injected and it is sintered or “cooked” into the shape of the mold with heat and pressure without going liquid.

As you can imagine the metallurgy or the physical and chemical properties plus the hardness of the finished part may differ greatly depending on the method and material used. The choice of material and forming method are based on many factors. Cost is always a big factor; and sometimes the wrong deciding factor.

MIM, just like dry firing will be (and is) discussed, debated and argued on gun forums for years to come. But like the big 3D gun model drama we just saw; by folks that really have no clue. Smith & Wesson, Glock and some others decided MIM parts were a good thing because they reduced their cost. (Not yours; yours continue to rise no matter what) And for some their favorite gun company giving the stamp of approval is all it takes. I’m a Smith & Wesson fanboy and they got this one wrong. But they will find that out eventually and stop the practice. Lets hope no one gets killed in the meantime.

BTW… I didn’t mean to imply that dry firing had anything to do with the FN striker problem. Just that its another physics, metallurgy and metrology issue that is easily overcome by a MFG saying it is okay or because someone has done it and their gun hasn’t fallen apart; it must be okay. Sometimes Engineers get it wrong. The test of a company is how they deal with it when they find out.

Thanks for the info. I recently picked one up and had been thinking about one of these. I have the trigger jig if anyone needs to borrow it.

      Something that I discovered recently was that, surprisingly despite the smaller size of my hands, the Glock 19 platform that I had carried religiously for nearly 20 years really wasn't the best platform for me.  Shocker!
      What I discovered was that the longer grip length of the Glock 17 not only put the grip's palm swell/hump in a location that fit my hand better, but I also benefited from using the the medium back strap as it gave me more surface area to get my support hand onto.  More support hand on the grip itself and not overlapping my dominant hand fingers means more actual contact with the gun and therefore better recoil management, less muzzle rise, and faster split times.
      My world had basically been turned on its ear.
      While I still wasn't a fan of the additional length of the 17 for IWB carry, especially with a compensator hanging off the end of it, the Glock model 45 suddenly made a heck of a lot more sense to me than it ever had previously.
      Consequently, I've started to part ways with most of my Glock 19s and have picked up two G45s as their replacement.  The added bonus of course is that the G45's slide is the same length as the G19's, so all of my holsters work just fine with them.
       
      This gun is my "pimped out" carry rig for when I'm feeling a little extra sassy and don't mind a little extra bulk on me.  I sent the slide off to DP Custom Works and had Doug mill it for an RMR and mill the front top of the slide with extra cocking serrations to make press-checks a little easier.  While he had the slide, he re-finished it in a tough black nitride, which looks fantastic and isn't as slick as the factory Gen 5 black nDLC.
      I added a ZEV Gen 5 curved trigger with their tuned ZEV Pro connector, ZEV suppressor height sights, a Crux Ordnance oversized mag release, a Silencerco threaded barrel, a Parker Mountain Machine comp, and hung one of my 1,000 lumen Surefire X300-UB lights off of it.
      The whole thing rides very easily in a Squared Away Customs "FOXTROT" outside the waistband holster or a Legacy Firearms Company light-bearing CRONUS inside the waistband holster.
       
      As for how it shoots, I've got the dot set for a 10-yard zero and stacking rounds in a cloverleaf within a 1-inch circle at that distance isn't a difficult task for me.
      ** Edited to Add: These photos were taken with an Agency trigger installed, before I swapped it out for the Zev curved trigger to keep things consistent across all of my Glocks **

      I saw someone mention an 80% revolver on another forum. Anyone ever heard of something that resembles This? Of course they had no links or detailed info on it.

      This is pretty cool. I don’t shoot competitively anymore, so I can’t justify the cost of one of these, but to me they are an excellent example of the shift in gun making.
      There is very little old school conventional “Gunsmithing” going on at Ed Brown. But there is a lot of high performance, high accuracy machining by quality Machinists, Programmers, and QA inspectors.
      I’ve spent my life in manufacturing. I’ve heard it all like “Things aren’t made as good as in the old days”, something must be right because “It is CNC machined” or something is special because it was “Designed in CAD”. I just smile when I see these kinds of statements.
      Truth is, we have far surpassed any that could be done quality wise in “the old days”. Unless someone is doing “One off” protype work or working in their garage; most everything is “CNC Machined”. And everything is “Designed in CAD”.
      Does that mean everything today is better than it was in the past? Absolutely not. These technologies still rely on the Machinists and the programmers (many times the same person) using them. CNC machines can make junk, and they can make it fast. These CNC machines only do what they programmer tells them to do. If he programs the part wrong; the machine will make it wrong. CNC machines are high drama. They require Machinists and Programmers that are on top of every little detail, every single minute. They require inspectors that are checking all critical dimensions, all the time.
      If you have high accuracy, quality machines, and you have the best Machinists and Programmers. You can make extremely accurate parts that don’t require any hand fitting; they fit together to extremely tight tolerances and work every time. In 1992 Ed Brown quit gunsmithing and went strictly design and manufacture. He retired at 65 and turned the business over to his family. With what he put in place; it can carry on.
      So, what does this mean to you? Well, it means you can buy a high-quality competition for gun for $2K instead of 10K. It also means if you need a replacement part, it can be shipped to you and dropped in without requiring a gunsmith.
      Sorry for the trip down memory lane, this isn't something new, but when I saw this; I saw a good example of a positive change with people involved that are dedicated to quality. I don’t own one of these guns, but I’d sure like to; I bet they are really something.
      Why doesn’t Smith & Wesson or Glock or anyone else do this? Because then they can’t sell their guns for $300-$400. But change is happening on a daily basis; someday they will.
