I own a Sig SP2340 and like it alot. The Sig pro models are Sig's first polymer framed pistols. Since Sigs are pretty much at the top of my price range, I chose it as a way to break in to the line because the pros are less expensive than the Sig classics. I have since added a Sig P228 9mm.

I have found the 2340 to be very accurate and 100% reliable. The only negative I can think of is the take down lever/pin is a real pain. The system on the classics is much better. However, after you field strip it a few times, it does get easier - no big deal.

If your pistol is in good condition, and with the night sights, I'd say you got a pretty good deal.

Go over to sigforum.com and do a search by author name for LUNDE. In his posts he has a link to a webpage he created of FAQ's for the SP2340. It has everything and anything you want to know about your pistol. Enjoy your new Sig!
