Summary

Extended basepad for XMacro mag

Tested to fit 22rds with following setup:

• XMacro follower
• TTI Versatile Extra Power Spring ([https://tarantacticalinnovations.com/tti-versatile-extra-power-spring/](https://tarantacticalinnovations.com/tti-versatile-extra-power-spring/))
• floorplate removed
• M3x4-6 screw

Will work with a p365 15rd spring but will not lock back.

I had a buddy manage to get 23rds with at trimmed p320 follower. You could probably also get 23 with at CSRG follower.

Length is ~140mm for competition (based on my competition mags. I don't have a gauge to fully test).

Print in at least PLA+. I recommend Nylon or Nylon CF.

Print with front of basepad facing down and 6 walls for strength.

I've done some drop testing on these in PLA+ (nylon should be better but I don't have any right now) and they should last at least a few drops fully loaded on concrete. I've done my best to strengthen the design while still fitting the magwell, but I've seen concrete break metal extensions too. What can ya do. I've never had one break, except when dropping mostly full on concrete.

Edit 2024/02/09: Reoriented file to how it should be printed. Added version with bigger gap for the mag lips in case you have some shrinkage or want it to be looser.
