I am very fond of neoprene replacement or OEM grips on my carry guns. They possibly saved my life one fine evening when a client elected to relieve me of my sidearm by grasping and pulling aside the outer half of my issued Bianchi breakfront duty holster. I got my right/strong-side hand around the grip before he could, and my left knee to his solar plexus disincentivized him from further silliness. First day of use of that nice, new holster--and he destroyed it. Sprung the rentention system completely. I had the old former holster still inside my locker, so after lodging my miscreant in the Graybar Hilton I re-fit the old scabbard onto the Sam Browne and kept on using it until we shifted to bottom-feeders from the roller-guns in 1987. And I still have that old scabbard. I still use Hogue and Pachmayr neoprene aftermarket grips, too.
