Thanks for the assurance, Kreyzhorse.
Kahr just brought out CW380, a less expensive version of P380. Its MSRP is $230 less than regular P380. Not sure what the street price would be, but much closer to your price limit.
I have absolutely no experience with Kahrs, but they do have very loyal following. Personally I would take the Sig, but it is definitely not a $300 gun and SA-only is not for everyone.
I didn't know this and am very interested in it. Some of my family carries Kahr and loves them.
I actually don't mind a SA trigger at all. The Sig is on my list but way on down the road when monies allow.
