For years I was "done" with double stack for carry, but still enjoyed them at the range. I was a 1911 guy, and when I moved away from that (for carry, still love them at the range), I went even smaller (I bought a Kel Tec Pf-9 which I never liked or trusted enough to carry, I got a LCP for pocket carry, I carried a SIG P290 most of the time when in a carry state, and when in a revolver mood I had a Taurus 85CH for over a decade). I don't live in a carry state, I only carry when in a state which will take my non-resident UT permit so I didn't carry full time. Thus, I never really got used to it and felt like I was broadcasting that I was carrying with even the smallest gun, so I kept going smaller. Then, last year, while on vacation, I took one of my winter carry guns when camping in VA in the spring. I found my double stack SIG P250 Compact carried just as easily as my P290 once I was there for a few hours and got used to it. With a good holster it isn't uncomfortable, and with all but the lightest color or tightest shirts it even works with tucked IWB carry. So, if it isn't much harder to carry and conceal a large gun, I decided that is the way to go. They are larger so they fit my hands better, they are heavier so they are more comfortable to shoot (which means more practice so I'm better with them, plus they give faster follow up shots), and all that before factoring the larger capacity. Now, in addition to my P250 Compact, I have a CZ P01 for carry, and I may pick up a Glock 23 as well (or maybe, since that is roughly the size of the P250 Compact and the P01, I may go with the G27 to cover all bases as far as sizes).
Of course, if I lived in a carry state and carried nearly full-time it is possible my choices would change and I'd mainly carry the P290 for the convenience. Hopefully, I'll be able to say soon (I will probably be moving to PA this spring or summer).
