I've only owned a few pistols, and I am surer happy with my xDm. Aside from the double charge earlier this year, it's run very well for me. I only replaced my original one with a new threaded barrel version as it was cheaper to replace it rather than buying an aftermarket barrel. I started out shooting my Grandfathers service pistol, and really want to get a nice 1911, but only after I can afford such an endeavor. I've got a good friend who's built a few 1911s and they are very smooth operators. He's going to assist me with one when I get the parts. I've shot my brother's Beretta 92, and it's nice pistol, but I don't like the external trigger bar, as I shoot left handed and it feels funky with my grip.
Currently, I don't own any 9mm pistols, so I'm probably going to get a Glock gen 5, just don't know if it's going to be 19 or 17.
