When I am talking about reliability, I am talking about WITHOUT cleaning it, which gun is the most likely to continue to go bang every time. Just put them in order from 1-8, these are the firearms in question. 1) Glock 2) Springfield XD 3) Smith and Wesson M&P 4) Sig Saur 5) Berretta PX4 6) Browning Hi-Power 7) Taurus Millennium 8) Smith and Wesson Sigma Just number them from 1 being most reliable to 8 being least reliable. This is all your opinions! Thanks guys.
