Some damn good information in this thread. I am proud of you guys.
SIG Academy, LFI, Gunsite, Thunder Ranch, all top shelf institutions. I attended Tactical Defense Institute in Southern Ohio and went through their level three handgun course. It's been a long time and when I get the cash, I'm going back for more. They are lesser-known, but VERY effective in marksmanship skill-building, tactics, law, etc.

As to weapon selection, James said it best when he said buy a quality pistol that fits your hand well and just "feels right". If a Glock doesn't point well for you, don't buy a Glock. XD's are excellent choices, especially the new M model. A lot of value there for the money.
I think that 1911's have come a LONG way over the last decade and if you buy a Kimber, SIG, S&W or any of the other top-quality brands you won't have problems. I had a Kimber for a while last year and it ran flawlessly.
When I can swing it, I believe this is going to be my next piece:
I go on the SIGSauer website and I get all kinds of goofy.
