Dyroe. I have had my .22 conversion on a Limited Custom (small frame 9MM) for almost 2 years . Had some trouble with the slide not locking completely, but after polishing the grove on the barrel for the extractor and the extractor, it works 100%. I am using CCI standard and have no feeding problems. I compete in the Norwegian "finfelt" division with the .22 and then put on the 9mm for the "militærfelt" division.,Great inexpensive practice with this kit.
