Dadgum, this is STILL going on? I hope the OP got what he wanted.
I will throw my $.02 in one the last two statements, yes a full size all steel pistol can be carried concealed, with right holster and belt selection - I did it for years with an EAA Witness 40. Believe me or don't, I don't care. I prefer my CZ P-01, also with good holster and belt. A Glock/CZ/Smith in a bad rig will be far worse than anything in a well designed holster. Not a fault of the gun at all.
Lots of hot air and bombast has been thrown around, and I will simply say again, I hope the original poster got a sidearm that fits him and his budget no matter what brand.
I think a mod said something about taking a 2000 round pistol course - whenever I can afford to do that I'll report back. Not likely to happen any time soon, no such classes offered within 75-100 miles of me, and bills won't allow it, maybe when I win the lottery.
