I'm very partial to a P64 in my strong side front pocket, in a DeSantis SuperFly holster. I've even stitched some elastic bands to the flap to carry the second magazine for it. 6+1 single stack, 9mm Makarov ammo (like strong .380, but less expensive and more available), a steel-frame pistol that's DA/SA with a sweet manual safety and is lighter than my standard-size poly-frame pistols and about the same weight as a stainless J-frame, and it's as reliable as a brick.
Of course, nothing is perfect. It requires a spring change to get a passable DA trigger pull and even with the spring change there's still quite a bit of stackup. But I tolerate it because it's almost exactly the same length, height, and weight as my .38 Spl. snubby while carrying two more rounds and being thinner so easier to conceal in a pocket.
