Buffalo Bore Ammunition Buffalo-Barnes Lead-Free 9mm Luger +P+ 115 Gr Bar. The lightweight bullet generates very little felt recoil which aids in fast follow-up shots. The all-copper bullet penetrates very deeply for a .355 diameter bullet of that grain weight. Expect roughly 13 inches (or 17 using 115 grain) of penetration in ballistic gelatin. It also features low flash powder which offers a huge tactical advantage to the shooter.
