Midway USA. has what you are looking for. Unless you plan on shooting 500+ rounds I'm gonna recommend you don't. I test fired mine about 700 rounds and had about 60 light hits and about 10 that made no mark. After the first 100 I thought it was great but I had 750 rounds and was going to be sure it was ok to carry I figured it better have 0 failures. Boy was I wrong. After putting it back to factory I put another 1500 rounds through it with 0 failures, about the same as before the mods. If you can't afford to test it thoroughly then I recommend against it.
