Great question, which Sig for CCW?
...
WM,
Got to tell you, my first gun, as listed below, was my first carry for these reasons:
I wasn't sure about caliber, so I went half way with the 40cal.. glad I did.
The Beretta, is both Slim in the grip, even with double-stack magazines for max load (here in Calif) of 10 rounds.
Length was what I deem mid-full size, and the slide is narrow, making it very CCW along with it is not a heavy gun.
Then I got the Sig P229R CT (crimson trace laser grips) 9mm.. It's my night home, SD/HD & nightstand, gun.
Then the Bug P232 SL for the wife, but it makes a wonderful yard-duty, ccw, for working in the front and back yard. Or, if occasion, dress, calls for small, it is an optional choice, but really, I would go with my Colt Defender for that purpose 90% of the time, or the new Springfield EMP 9mm coming in 10 days.
BUT, when I got my full size P220R 45, 8 round mags, I compared it to a P229 Carry and the P220 Carry, and I was very surprised, and is why I bought the full size P220, in that, the grips are thin, being a single stack mag compared to the P229's double-stack mags and grip width, along with, the P220's slide is MUCH narrower than the much thicker, heavier, P229, or P220 Carry, slides.
The final clincher for me, was it was just a hair over 1/2" longer than my Beretta, and the same IWB holster that I carry my Beretta in, works perfectly for the P220R (full size gun) as well. Both guns are Lightweight guns for their size IMO making them very CCW for long periods of time, least for me.
Just do a side by side comparison at a gun dealer, to see what I'm saying, along with, "the feel" of all these guns in "your hand", the grip, along with the weight, and balance, in point to aim, pulling it out, up, and aiming, and go with what feels BEST to you, the most natural, as if part of your hand and arm.
You can't pick a loser, we all agree on that..
Enjoy this, I know you will, along with, more guns to follow up the road, trust me.. lol
