For ccw , I've grown very fond of my Kel Tec PF9, I can almost buy 2 Kel Tecs for the price of a P238. My PF9 is , of course , in my favorite caliber (9mm), and very concealable. It barely fits in a pocket, so I may get a K/T P3AT(oh darn) even though it is a little small in my hand, so I'll try adding a finger rest. DAO and Crimson Trace grips available, too.
As far as the Sig Mosquito goes, it wouldn't bother me to have to get another Ruger 22 5.5" bull barrel auto instead of the Sig. I sold my first Ruger 22 many years ago and regret it now.
