The sigpro is a good weapon, I have a 2340 in 357 sig that is a tackdriver. I have had it for about 18 months and probably 2000 rounds through it. There are definite differences between the pro and the Classics. The pro does seem a little bigger in the grip, the classics have that quality feel to them. I am suprised that the sigpro hasn't captured the law enforcement market big time, mine bought as a LEO was $449.00 out the door w/siglite night sights, which is about the same as the LEO price on a Glock w/out night sights. When I bought mine, duty holsters were a problem, thats been taken care of now. As far as Sigs I like the 225 is the best, closely followed by the 220. I also have a NIB never shot 229 2 tone w/siglites that is just too pretty to shoot. I actually bought it because the serial number means something to me. I think in 9mm the choice is obvious the 225. When you move up to 40/357 the choice is more difficult, the sigpro wins by a little, mine has the best factory Sig trigger of any that I've handled, the drawback is the lack of "Quality Feel". That feeling you get when you release the slide and it "thunks" into battery, Glocks dont have it, sigpro almost has it, Kahr has it, USP's have it and Sig Classics perfected it. Pick the one that you shoot best with, practice with it, become proficent and enjoy. When comparing anything you will get as many opinions as people you ask.... Stay Safe
