SIG/GSG 1911 +4 Base Pad
thingiverse
Replacement base pad for stock GSG/SIG 1911 single-stack magazines adds +4 capacity for a total of 14. If you can source a stronger spring, it's probably worth swapping the stock one out to prevent feeding issues. Despite this, it seems to be working fairly well without modification. **Installation Instructions:** - Remove original base pad by pushing pin in through the bottom and sliding pad forward. - Remove the pin at the end of the spring and discard. - Push 3D-printed base pad onto bottom of magazine. - Optionally insert a ~20mm M1.5 bolt through hole in back to lock base plate into place (the base pad stays on with friction fit fairly well, so this isn't strictly required).
