WTS: Glock 31 Std Sights Knoxville, TN

I have a stock as can be Glock 31, case, 2 mags, etc... Everything it came with. I put 30 rounds through this gun and just don't really have any interest in it over my 17. I'm looking for $400.00 firm within the Knoxville area. If you're interested please let me know. Only trades considered would be a 23 or 26.
