An improvement over the polymer OEM base pad, Obsidian Arms P320 Base Pads are machined out of 6061 aluminum. They are much more tolerant of being dropped on rocky or cement surfaces for heavy tactical or training use. The added weight of these base pads also aids the magazine in dropping free from the magazine tunnel for rapid and consistent reloads. This base pad is specifically designed for the 9mm 21 round magazine and .40 S&W 18 round magazine. It adds one to its total capacity for a total of 22 rounds or 9mm or 19 rounds of .40 S&W using the factory spring and follower. Still fits in a 140mm gauge for competition shooting.
