Good point .22, I don't know how old my 929 is but, I have personally put a BUNCH through it. It keeps right on going. But I clean my guns EVERY time they are shot. So they are always nice and clean and lubricated. The killer of a rim fire pistol IMHO is folks just DON"T clean them. I hear people all the time say "well I have about 1000 rounds through it and I've never cleaned it" as if thats something to brag about
. Just because its a .22 does that really make it any less worthy of a cleaning patch?
