Conceal: light-1911 .45 ACP any mfg
heavy-HK MP5
you conceal an MP5?!!!! how big of a coat do you wear?! is a 3 -round burst model?

i've carried a couple of different pistols. first i bought was a Rossi 4" .357. I like it and still have it. puts a nice big hole in bears! i've also carried a Kahr CW40. i love the pistol, but couldn't hit a thing with it. shipped her on down the road at a gun show. carried a P64 in 9x18 mak. i was accurate with it and i liked it, but as an all steel gun, it was a bit heavy for working in the office (not a gun friendly office, so deep concealment was paramount). then i had a diamondback .380, which i liked, but .380 was, well, .380. now i'm carrying a S&W 637-2 airweight in .38+P. i've always wanted one, shoot them pretty well and now i have one!
if i was looking for a .44, i'd probably head to the safe and grab either the nickle or blue S&W Mdl 29 my dad has. both 6.5" barrels. hard to go wrong with S&W.
Rugers are good guns, just don't do a whole lot for me looks wise. a friend has a .41. nice pistol. shoots very well, but single action. for me, well, colt and S&W would be where'd i'd look.
