i haven't tested this design yet. its a glock 30x (g30 slide g21 mag) that is designed to use polymer 80 style p940sc rails. I don't have a set on hand so i don't have the means to test this model yet. I uploaded a step file in case anyone else wants to mess with it.
22 cal AR 322 mag round body v2
BETA: g30x gen 5 grips
Alpha: G19x style grip with PSA dagger rails
