I have three .22 pistols, only one of which is threaded so far. The threaded one is a .22 conversion on one of my Sig P226s. It's been dead reliable. The other two pistols are a PPK/S in .22 and a Ruger MK III. I'm definitely going to have the Ruger threaded but the PPK/S is a classic and I'm loath to destroy it's collector value.

My .22 can is a SWR Warlock. I also have a .30 Omega for my FAL and other assorted 30 caliber rifles.
