I shoot a 1911 in competition and have an M9
The M9 has two drawbacks - the DA / SA trigger and awful sights. Once you get used to it, it is a very shootable/accurate gun.
I have shot the M17, right out of the box, with no familiarization, and it is as close to ideal as you can get.
Sig did an excellent job. Looking to free up some space in my safe for one.
I’m a Glock guy. Something about the 320 just doesn’t do if for me. Nice trigger. But not a fan of the grip or the fact that the barrel sits a little higher than my Glocks. But, that is a Sig thing, I think. I had a P229 years ago. First pistol I ever owned. Shot awesome but I didn’t like that higher bore ratio.
Now, the 320 X-Five is something I can live with, I think. Got a chance to put my hands on one at the NRA Convention in Atlanta. Man o Man, that is a nice pistol. But definitely not something you’re going to use a every day carry gun.
