Of the 7 semi-autos I have owned at one time or another: S&W 1911, Beretta 92FS, Springfield XDM .40, Springfield XD-40 Subcompact, Browning Buckmark, Ruger P95, and Ruger LCP, only 3 of them have had a flawless run from the beginning. They are:
1. Springfield XD-40 Subcompact (~2,500 rounds)
2. Ruger LCP (only 75 rounds so far)
3. Ruger P95 (~1,000 rounds)
All the others had at least 1 malfunction of some kind. Usually right out of the box, first couple of mags, then the problems go away. But the 3 listed above ran perfectly out of the box. I'd give the win to the XD-40 SC, since I've shot it the most and shoot it well.
