Contact MechTech today about Coonan conversion

Recommended Posts

I have 3 pistols chanbered in .357 Magum.  I have 3 rifles chambered in .357 Magnum.

I want a .357 Magnum semi-auto.  I know, I know.  Why not get a 10mm?  Why not get a .40?  Because I reload .357, have a ton of .357 ammo and don't want to introduce another caliber.  I so eagerly want a .357 semi-auto carbine.

If anyone else is interested in one of these conversions, please contact MechTech today and show your support.  They won't build a conversion unless you ask.  They are already doing conversions for other 1911s.  I want them to build an upper for the Coonan 1911.


Please show your support by contacting MechTech today: https://mechtechsys.com/Contact/tabid/6648/Default.aspx

After contacting them, please share this post to other gun blogs so the interest can spread.  I don't want to have to pay a gunsmith thousands of dollars to do this conversion for me.


I wasn't quite sure whether to put this post in handguns or long guns forum.  Technically, it's both.

.357 Mag is my favorite handgun round.

However, making it semi auto is impractical. What is not impractical is  making the .357 Mag into a rimless without changing it ballistically. Of course then you have two different rounds. So then you might as well go with other available choices; .223, .30 Carbine, 300 Blackout,  or the King .308 Winchester for your carbine. :)

But you are certainly going about it the right way. Get a group of people to tell MechTech they will buy one; and it just may happen. Good luck.

I want to stockpile 1 357 cartridge, not 2.  Otherwise, I'd just go with a 10mm carbine.  That's close enough to the 357 in power and ballistics.

      It appears that Colt is making a new King Cobra model revolver. I saw an ad in Guns & Ammo magazine this past issue. Makes me giddy that they may reissue the Python and my fave...the Anaconda 😁

      So I'm thinking of upgrading my carry from an gen 1 LCP to a micro 1911 (I like the platform and that's what I typically shoot).  I understand for 1911s, we check the barrel to slide to frame fit and that's typically an indication of quality/accuracy.
      I've handled about 3 or 4 different Sig p938s and a Springfield 911 recently.  And they are loose - lateral movement of the slide, able to press down and move the barrel, etc.  
      Did I just happen upon poor representaion of these guns?  They are just made with super loose fit to improve reliability?  How accurate are these guns?
      Thank you!
