already done my friend; you can get a CCW with 5 different backs, 2-1/4" SS clip, GI/Bianchi UM84, Tek-Lok, G-Code RTI, SafariLand ELS base, and 2 different shell retention springs: the original, like Choate and MME; or the new leaf, similar to the PM/Otto. Also, the CCWs convert to M16 mag pouches in less than a second!
where are all those variations available?
