Hello, I've been reading over the threads on the forum for a few months, looking for information, and decided it's time to register. I acquired an M40-A1 last October, and it has become my favorite polymer frame pistol, beating out pretty much everybody else's offerings. and I can see why it can be referred to as the Glock killer. I have almost 300 rounds through it, if not for the ammo shortage, I'd have at least twice that through it, but, have had no feed or extraction issues. I liked the .40 so much, I picked up an M9-A1 this past weekend, hopefully get it to the range this coming weekend. As soon as I can find one, I will acquire an S9-A1.
