In no particular order:
1. SigArms P220 Match
2. HK USP 45 Tactical
3. Glock 21 SF
4. Wilson Classic Super Grade
5. Kodiak Precision Custom Gun with a Caspian 6" damascus slide, Strayer-Voight frame, Schuemann AET barrel, all put together by Don Golembieski himself.
Now the reasons.
The Sig and the HK are maybe the most accurate and reliable guns out of the box. Period.
The glock is as dependable as it gets, is a masoquist weapon, and have a fairly good capacity, and before you start with the xd45 thing, I like the feel of the glock, yes the grip feels different, but it allows you to have you hand closer to the chamber, and somehow gives you more control, at least for me.
I think no explanations are needed for the last 2 weapons. I started with 1911's and they are almost perfect.
