Carbine Conversion Unit questions for 1911

I have had one for several years now. It works great!

If you use good magazines, it is reliable. It is accurate, or as accurate as I think a pistol caliber carbine needs to be.

Its appearance is not as good as its performance. The receiver is sheet metal. It works well, however.

Mine is .45 ACP. I sort of wish I had one in .38 Super, also.

While mine is for the Glock Model 20, it is well made,
reliable and makes the 10mm more useful at long range.

My wife gave me a .45 ACP version for Christmas. It is very accurate but surprisingly heavy.

I use a Kimber Gold Match frame as the lower assembly. The only problem I had was that it would not reliably feed using Wilson 47D magazines. But it fed and functioned perfectly with the Colt-style magazines with the split sheet metal follower that have the little raided dimple in the center of the follower.

I was shooting medium power 200gr RNFPs and some more heavily loaded 225gr TCBB loads. The bolt is very heavy (I guess it has to be as this is a blow back operating gun) and the bolt recoil spring is also stout. Sometimes the last case would not fully eject -- the case would get caught between the returning bolt and the front edge of the ejection port. As I recall this was with the 200gr loads.

I was using a reflex sight on it but have since mounted a 3x5 variable scope. I have not yet shot it with the scope. But I expect this will allow it to get out to 100yds pretty easily.

Fun

Have had one for quite a few years..may be one of the first ones. I bought it one in 460 Rowland anticipating some south Fla hog hunting but never got around to it. Its lots of fun to shoot in 45ACP. I think they all have a peculiar "twang" when they are fired..maybe the recoil spring?? Mine functions well with all my mags and the Wilson 10 rnd is nice. There was a company making large cap 1911 mags but never tried one.
If you have a 1911, they are a pretty neat accessory.

Glock .40 caliber

I have one for my Glock 23 lower and it can also work [ according to manufacturer ] with the Glock 19.

Its in .40 caliber and is a bit heavy for a pistol caliber.

Function was gtg,but taking it apart was a bit more of a hassle than I expected [ first time ? ] and that would not be a good thing if ina real hurry to transition.

I fired a friends in .45 acp and that is the one I might have gotten in retrospect.

Still a very handy tool that can be left in vehicle and NOT be a firearm until assembled using the NEEDED pistol for the lower.

Haven't shot one but I handled it in a store.

It's nicely made. No doubt about that. But it's HEAVY! ! ! ! Quite a bit heavier just for the upper unit than just about any other handgun caliber carbine seme auto I've hefted or shot. All in all I'd say that the complete conversion ready to shoot would be about the same weight as a Thompson. And if you've ever shot one you KNOW that this is a rather heavy weight comparison.

Given the weight I'd rather just buy a Sub2000, JR Carbine or Thureon that takes whatever favourite handgun mags you have. It'll be a lighter overall package and lack the time needed to move your frame from handgun to carbine and back.

Will a MechTech work with an officer 1911 frame?

Bigfatdave, according to their website, yes.

Thanks, I missed that last time I was playing on their site

Hopefully they'll catch up with orders, I've got an order sheet filled out, looks like the total will be $530 + shipping

That weight does reduce felt recoil! I don't think they're as heavy as a Thompson or a Suomi, or maybe even a Sterling. None of the older, SMG-based pistol-caliber carbines are lightweights. The lightest of the SMG clones may be the MAC-based carbines by MasterPiece Arms.

I think that one of the reasons the M-T feels so heavy is that it looks like it would weigh less. It's gotta be lighter than a Garand, for example!

All my best,
