The TRU-17 Magazine Base Pad is a direct replacement part compatible with P365 XMACRO magazines. The design of the TRU-17 makes it easier for users to load the full 17 rounds into the magazine. The TRU-17 base pad adds weight to the bottom of the magazine, helping to drop empty magazines more smoothly. A larger grip surface allows users to quickly index spare magazines from holsters for faster reloads and makes it easier to remove a stuck magazine. RSR -
