1911 Pistol (in .22 Rimfire)
I recently purchased this German made Model 1911 chambered for the .22 rimfire. It is a high quality handgun made by
German Sport Guns (GSG), and it's imported by American Tactical Imports (ATI) in Rochester, New York. After working on handguns for 30 years, I know that it's a challenge converting the 1911 into
a reliable .22 rimfire. The biggest problem is making it function with such a weak cartridge. It's difficult to make the slide lightweight enough to function reliably - even with a straight blowback
design. |
Before I had a chance to try my latest handgun, I found this picture in an Internet article. Some
shooter had the exact same pistol I just purchased, and he explained that his barrel bushing bent during firing. It sent the recoil spring flying down range. That's something you'll
never experience with a Model 1911 in .45ACP.

Well . . . . it's easy to replace the aluminum part with a steel barrel bushing (I had a pile of them in stock). However, I know the manufacturer used aluminum to cut every little bit of weight to make this pistol function. After replacing the bushing I also wanted to cushion the slide-to-frame impact. |
Before I fired my new handgun, I wanted to turn down the rod guide to accept an "extra" rubber recoil buffer. After all, the same slide force was still there after replacing the aluminum barrel bushing, and I didn't want to let the new "steel" bushing damage the aluminum slide. |
This shows the rod guide BEFORE and AFTER my modification. The end with
the large diameter was reduced by .080" to accept an extra rubber recoil bushing. |
I made a few other improvements that include a crisp 3 pound trigger job. This handgun is not designed to be a carry
gun, so I removed the firing pin block from the slide. I also removed the wierd magazine safety on the mainspring housing, and I reduced the sear spring pressure on the grip safety. The rearward tip
of the sear leaf spring needed to be rounded and polished. This is an important step, because it prevents the leaf spring from digging into the soft aluminum grip safety. |
