USPSA Limited and Single Stack shooter here and wanting to get started in CO. Bought an M&P Performance Center 9L and want to find a Leupold Deltapoint 2 to put on it (not a new DP Pro as the don't fit) want to be able to co-witness the suppressor sights. Anybody got any ideas or connections for finding one of the older model RDS???? Check your safes and Junk drawers guys....
