I have a lead on a short (18") 500 with extended magazine tube and synthetic stocks for $300. Is this a good price? The 500 seems to have a good reputation.
I'm not sure how it's possible to have an 18" barreled 500 with a mag extension. 500s have a large threaded hole in the end of the mag, so you can't add an extension. There is a 20" barrel version that has a LONGER mag, but it can't take an extension either. 590s can take an extension, but they aren't 500s.
