When it Comes to a Carry weapon I Consider the 5 Cs:
Concealability - how easy to eliminate printing?
Capacity - the more, the better
Caliber - the bigger, the better
Confidence - when I pull trigger, will it go BANG!? Will it hit what I'm aiming at?
Cost - hard to put a price on your life, but realistically, not everyone can afford a Rohrbaugh
Obviously, all these Cs interact and there is give and take in every variable of the equation. For example, increase caliber/capacity, decrease concealability. The Cool thing is that there are SO MANY excellent Choices out there to fit your body type, shooting prowess, environment, and budget.
In my case, after MANY, MANY trail and errors, I carry a Seecamp LWS32.
My next door neighbor, who is also about 5'11" and 190, carries a 5" 1911 Springfield TRP. Go figure.
