I've been collecting/shooting Sigs for the last 16 years.
I also own Berettas, CZs, Colts, and S&W wheel guns. I had an HK, but I sold it to buy another P226.
I'm up to 17 Sigs with a new P226ST 9mm coming my way by the end of the week. I've only had one problem with one of my P226s and Sig fixed it with a turn around time of only 9 days (bad sear and hammer).
I won't even venture to guess how many rounds that I've fired through my Sigs over the last 16 years. Through that time, the only ammo that I've had a problem with was Fiocchi .40S&W in my P229 DAK.
I like the way Sigs controls are set up and the quality of their workmanship.
I do think that the older stamped slide Sigs were made with a little bit more attention to quality and finish, however, I just think that its a sign of the times. I'm sure that Sig is turning out many more "units" per year then they were back in the early to mid 90's.
I like some of the new designs that Sig has coming out and especially the DAK trigger system. I'm glad to see that they aren't sitting on their hands while other mfgs are getting into new and different designs. I do wish that they would bring back the "classic" design - no rails or tails and offer that as an option for those who don't want them.
I shoot a P226 in IDPA and my main CCWs are Sigs (P239 SAS 9mm and a P229 .40S&W DAK)
I know that Sigs aren't for everybody, and I don't get upset when people bash them - to each his own. I'm happy we live in a country where we can have so many choices of different firearms.
I do like the other brands and guns that I own, but for me, Sigs are #1
