Need to define "conceal". When it comes to concealing, I have done that with I think every gun I purchased including my AR, sneaking them into the house under my wife's nose after a return from a gun store. Better she find out later after I make up a good story - like the 75% Off Founders Day sale.
But for what are my primary CC guns, it would be my Shield, XDs, and LCP. IWB and Pocket carry on all three.
