have a gun show coming up in a few weeks and wondered if any of the regulars here that know something about Sigs and 226's, in particular, have any pointers on what to look for as I evaluate the used 226. i saw the wear scale about the finish and I know to check for tightness of the slide and trigger etc.......any quirks or special time proven wearing to watch for?

Have I been broad enough?

If you've seen the wear guide, that's really the only 'Sig specific' stuff I could think of.  Everything else would be same as checking any used semi-auto pistol over before buying
