This magazine sleeve is designed to fill the gap that occurs when a 15 round P320 magazine is inserted into a Sig P320 with a Sub Compact frame. It performs the same role as the x-grip.
This model was built around the 9mm platform so I don't know if it will fit other calibers. This part shouldn't generally receive much impact, but if you're going to use it with a edc magazine, I would recommend printing it with a filament with strength >= ABS
Enjoy and let freedom ring!
ABS: The ABS model has some slight changes in size to adjust for any shrinkage. I print it @ 230 degrees with 80 degree celsius bed temp. 5-10% Support density.
PLA: Standard PLA settings. 10mm retraction @ 60mm/s printed @ 210 on a 60 degree bed.
Have fun, shoot safe and defend the second!
