After running a search in General Glocking I found several older post on Rebuilt Glocks. I have the option of doing a three way deal with the shop I purchased my G29 from. He did not want to take a G20 in on trade because it is a rebuilt and 10mm's do not move well in this area. The guy that runs the shop "Matt" called me to know if I would be interested in a 3rd Gen G20. The gun is at his shop and I am suppose to meet the gun owner at 2:00pm today at the shop. Matt says it is in very good condition some slide wear. CNSxxx The numbers all match. Is their anything I should look for specific to a G20 Rebuilt? Did the CNS have any known problems The G20 was built in 4/98 and rebuilt in 6/00 The owner bought it as a rebuilt but has only shot it a few hundred rounds. He is trying to finance some $900 shotgun.
