I have always been fascinated with caliber conversions to switch from centerfire to rimfire.
I have a revolver conversion that changes .357/.38 caliber revolvers with 2 to 6 inch barrels to .22 l.r. Accuracy isn't bad but POI is drastically changed.
I have a Colt conversion unit with the floating chamber that is only marginally accurate and the floating chamber gets very dirty, even with copper plated ammo. It is a complete upper with its own extractor / ejector in simple blowback design and a reduced power recoil spring.
I also have a .22 conversion for the Swiss P210s. The quality is excellent, as can be expected from SIG. The slide is lightened and the ejector is located on the top of the magazine. Accuracy is pretty good.
Finally, we get to the Walther P38/P1. When Walther developed the conversion, they decided to use a barrel insert, that fits into the standard 9mm barrel, which has the locking block mounted to it. The slide was lightened and the conversion was cut inside, so that the locking block could not engage. The front of the slide has a cut out on the bridge to easily identify it as a .22 conversion. The ejector is also mounted on the mag. Accuracy is not bad and POI is right on.
There are also 4mm M20 conversions but the ammo is more expensive than centerfire. This one is a simple insert for 9mm pistols.
I also have a couple of conversions for shotguns and a 12gauge to .38 Special has POI spot on and is accurate but for the price of it, it also should be.
Does anybody else enjoy conversions as an understudy to a centerfire pistol?
