With California, you are required to list up to three pistols that are to be carried. My very first choice was to carry the platform I was most familiar with. I shoot and compete with 1911s, so it only serves right that I carry one also. My Kimber Classic Royal fullsize was going to be it.
But, the weight wore me down by the end of the day, so a new lighter and more compact pistol was to be searched. I had a few criteria that I required: polymer, compact, and in SAO, DA/SA, then DAO in that order. Reliability, and durability were already a must. Lastly, either in 9mm or .45 since I have standardized all my pistols to those calibers.
A few came to mind: HK USP compact, HK P2000, XD9, Glock 19, and the Walther P99. The XD and G19 were already out since I preferred a manual safety or a DA first shot. I trust my trigger finger discipline, but I still had a mental block much like how others don't like to carry cocked and locked. What it really came down to was the USPc, P2000 and the P99. I didn't like the new P99s, and the older ones were nowhere to be found.
The USPc and P2000 were neck and neck. There are numerous USPc vs. P2000 threads on here, and I've given my 2 cents on it since I thought about it heavily.
The USPc had the capability to carry C1, and was available in .45ACP
The P2000 was slimmer, more ergonomic, felt more compact, better pointability, and had a smoother trigger. When it came down to it, it really fit my CCW needs.
I ended up with a P2000 V3 in 9mm and can't be happier. Obviously my thought process and back and forth thinking was a lot more strenous, but I'm glad I took my time to decide on the weapon that fit me best. No regrets.
