This is my first posting on this web site. I am by no means an expert on any sort of firearm. I do not hunt, not because of any feelings I have toward wildlife but because I don't like cleaning the kill. If I'm not going to eat it I won't hunt it. I love my M40. It is my first pistol. I bought it used and paid a reasonable price for it. It fires every kind of round I put in it, though it did jam once with an aluminum shell. I've shot 1000 rounds through it, employing brass, steel and aluminum shells. I have read reviews of certain ammunition that say this gun or that gun would not load them properly but the M40 does not seem to care what rounds I put in it. The level of accuracy I manage with this pistol astonishes me because I am right handed but I can only see from my left eye. My only problem is learning to keep my thumb out of the range of the slide. :?
