To carry a handgun well concealed, I find the clothing is more important than the gun. It's hot here now, with temps going in the high 90s and some days topping 100, so a small gun is about all I can get by with if I am actually concerned with concealment.
Much of the year here, about 7-8 months, I have no trouble concealing my 4" N frame S&Ws and even sometimes my 6-1/2" 357s or 44s too. But when the dress of the day is jeans and a tank-top, concealment gets harder for a larger gun. My "summer city gun" is a Kahr PM in 45ACP and even sometimes a Ruger LCP in 380. But when I can I carry larger 44s and 45s and sometimes 6.5" 357s
