.357sig, get outta my head!
I've been shooting IPSC for a few years now. I've shot the Glock 34, Glock 20 (.40sw), SA 1911, S&W 1911, and now I'm using a SV (which is a whole 'nother story). I say this 'cause owning a 1911 which works well does not mean that all 1911's are reliable. Bottom line is, I've seen 1911's fail ... and I've seen Glocks fail. But, far more 1911's than Glocks. And, my Glocks have never failed ... not once ... even the Glock 20 using a .40sw bbl, and the 10mm mags ... not once. I also own a HK USP .40 ... never shot it in competition ... but, I actually used to have twins and sold one to my buddy to shoot in competition and he's never had a problem ... not once. As it is, my other HK USP .40 does nightstand duty ... admittedly, in part, because I have no holster and mag-holders for it suitable for competition and I favor other guns for that purpose.
IMO, for .45acp, I'd go with Glock 21 (only 'cause it has higher capacity), then the Sig P220 (better DA trigger, IMO) and then the HK USP .45. However, I'd consider .40 just as effective and, in that case, I'd go with Glock 35 (or Glock 20 w/.40sw bbl) (only 'cause it takes a bit to get used to firing DA, then SA), then Sig P226 .40, then HK USP .40. And tritiums on it ... absolutely! Even with a light ... especially with a light! Also, if you get any Glock other than the 35, get a 3.5lbs connector installed ... just about any decent gun shop will do that for ya in 5min for about $30.
Also, I'd have to agree that I don't find anything "traditional" about the SW99.
Also, FWIW, YMMV, I'd avoid Kimber like the plague. They're not the quality they pretend to be. Cost me $150 on a brand new gun ... not to mention 4 others that never worked right outta the box. If you want a good quality 1911, go with S&W or the Sig GSR. If you've got money, go with SV, STI, or Wilson. (Actually, you can get a really nice STI for about the same price as the "fancy" Kimbers ... ~ $1000). IMHO
