UPDATE (20160222) V_2-9 is the new design which contains a glock-style trigger safety. These are printed separately since I was having issues with the safety becoming trapped and not working properly. Separately these work amazing. Hope you guys enjoy.
(20151004) V_1-5 (Non-safety) This design has a Salient Arms International style look. I haven't tried yet but anticipate shrinkage depending on the filament you use. I would suggest increase the print by 1% on each axis, but like I wrote below, it will work at regular size with some sanding. Thanks for looking!
Make sure you utilize the support material for the openings. Without increasing print dimensions, you just have to hand sand the inside of the holes a little to get the two pins in, very minimal work. You can fit them exactly how you want the tension to be on them. Printed it out in 1.5 hours, sanded the pin holes for all of 3 minutes and put the gun back together in 2 minutes. Very easy. Hope you guys enjoy.
