For a registered receiver? I'd need bolt, barrel, recoil assembly, and magazines.
Who makes a .40S&W conversion?
- Thread starter seachnasaigh
- Start date
I’ve got a 40 S&W conversion kit made by barrel xchange (see below).
It appears that it will work with a few calibers too (obviously, for 9mm with this bolt, you’d need a 9mm barrel and so on). Apparently, you can use standard magazines too.
I haven’t tried this kit but appears to be really nice and well made.

Troy Edhlund makes quality Uzi and 1919A4 Caliber Conversion Kits. I have one similar for my Mini Uzi and it works well. You can still use your Uzi Magazines, but in .40, you will probably be 2 or 3 short on capacity. The Bolts are "engineered" to use the different calibers, but make sure you use the "right" barrel.
If you have ejection issues, go back to "fundamentals". My .40 Bolt would not eject and when I checked it, it did not have extractor or pin. It was one of those Billy Bob Thornton "Slingblade" moments..."anybody got any gas?"

I have one from Troy also. Both in 40 S&W and 10mm. It's made for the stamped feed ramp. I have never been able to get it to run right. It's all due to not having a good type of magazine.
41ae magazines, the rounds don't stack correctly, 9mm magazines are to short front to back. For 10mm, the 22 round pro mags work until the rounds get past the ribs on the sides, then they don't stack correctly. I never tried my 16 round IMI magazines.
The only people that say it works are the ones that are using the grease gun lowers for the UZI, with the GG magazines.
I wish someone will start making GG lowers so I can buy one to try.

That was my experience as well. GG mags work great for .40/10mm, the others not so much. I posted my attempts with photos here on Uzitalk several years ago. This included adding some internal ribs in a .45 Promag to get the rounds to stack better.
I also got a .357 Sig barrel with my setup, and those didn’t like any mags, including GG mags. I did get a mag from Troy one year at the Creek, which was modified from a 25-round 9mm mag. It seems to feed anything. Unfortunately he only had the one.
I also have a 40/10mm setup up from BarelXchange.
When I got it he mentioned 41 A&E mags were great for the 40.
Although I never tried them.
I don't shoot 40. or even have a 40 barrel.
( maybe next barrel run eh. )
I did however source a grease gun lower for the 10mm barrel.
One thing I never see is Troys 40/10 setup come up on the used market.
Despite everyone saying they want one.
I picked mine up from Troy about 2004 or 05.
It's stamped 40 S&W and has a very very low serial number.

Practical Solutions has a wait list for GG lowers, but I think it is several years old and not much has happened in that time. I think they have been focused on the .22 conversion kits and tungsten bolts. But maybe if a bunch of people add to the GG waiting list it’ll put it back on their radar.

I tend to select guns which use NATO standard cartridges because of the ammo availability. .40 S&W is nearly as easy to buy in bulk because it is ubiquitous among law enforcement here in the US. If I'm going to be firing full auto, I'll want to be able to buy ammo in bulk.
ATF has just cleared my application for a tax stamp for a registered receiver Uzi which comes with 9mm, .45ACP, and .22LR conversion kits.
I have a case of IMI (Tass) black tip 9mm, and a case of IMI subsonic blue tip 9mm. Bring on the zombies!

I've been off the boards dealing with family issues and semi retired.
I lurk around once in a while.
For the guys that weren't able to get it running in 40 cal/357SIG, Here's some info.
The only 9mm mags that will work for 40 cal or 357SIG are the 25rd Star marked Izzy mags with the raised strap on the rear. They will only load about 18 rds.
The best mags were the 41AE or 45 acp mags. BUT you need to adjust the feed lips to hold the smaller dia case properly and present the rd at the proper angle. It's not hard to do and can be done with a small pliers or crescent wrench. You want to bend in the rear 2/3 of the feedlips to hold the case. Those will hold 20+ rds.
Make sure the rds are presenting at the proper angle when you look at it from the side.
The 41ae and 45 acp mags will also run 10mm.
If you want your mags adjusted, I'll do it for free, you pay postage both ways.

I still make them
Actually, LE is really moving away from .40 S&W (going back to 9mm). If you like this caliber, I'd advise purchasing it now, as I believe it will soon go the way of .357 sig and be a dead caliber.
As Tom Wright used to say, "these are the good old days." RIP Vegas!
Yeah, I think we're in a transition period, but in my experience, Cops and PD's are (general rule) into saving money. I don't see the .40 S&W lasting long term when the bean counters see that the FBI and others are going to 9mm.
I like 40SW for SMG matches. Suppresses well and hits harder than 9mm for steel plates. I don’t care about saving the brass and you can sometimes find 180gr jacketed cheaper than 9mm 147. Once I run out of brass or people stop giving it to me, I’ll probably stop reloading it

What parts do you offer, at what price?

I also wondered what he was referring to in that cryptic post.
BTW... Troy you looked too young to retire at SAR.
Hang in there. The industry needs you!barrelxchange

The parts are a conversion, for FA it's a bolt and barrel, you have to sort out mags (promag 45acp mags). Bolt will run 9mm and 40.
For a semi it's just a barrel, though you need to adjust the extractor tension a little to work for both 40 and 9mm
Other options are: If you have a 45acp bolt you just need a barrel and the mags.
You can also send me a bolt and I'll mod it for 40
