Sub-compacts are fair, but I'm a firm believer of "pocket" pistols for carry, and full-frame for other use. The smallest I really care to go is the mid-size, semi-compact types... think Glock 19. I can't stand how small the grips are on sub-compacts and other tiny guns (Like the PPK, my little finger overhangs without the added magazine mounted finger rest... the PPK/S frame works much better)
