I have pictures somewhere of my Glock 22 in two pieces.....so I am with you. If it wasn't an HK, I would go with an M&P in .40 or .45 as my next choice. In an all steel gun.......I got to shoot a good bit of someone else's ammo through the stainless SIG 10 mm and liked it, but a USP Expert with +P .45 or .45 Super would be my ideal for the Modern Semi-Auto Field Gun.
