My local Glock armorer was telling me about it. He said that Jim McNally used to work for Glock and while he was there developed this trigger modification which basically makes your glock trigger about the same as a Kimber. He tried to sell Glock on the idea of offering it as a modification for competition glocks, but Glock wanted no part of it (liability reasons), so he quit and now travels around to pistol matches offering this trigger job for competition glock pistols. Apparently he does not go to the GSSF shooting matches. I'm guessing it's because he would not be welcome at a match sanctioned by Glock because he is an ex-employee selling a modification that Glock didn't want anything to do with. Just wondering if any of you GSSF shooters have heard of or have this trigger modifcation.
