Gen 2 P320 Printable Magazines

cults3d

Introducing Gen 2 of the printable Sig P320 9mm magazines, featuring improvements to the side wall thickness, geometry of the transition from double to single stack, follower geometry, and general fit/finish. Again, these are plastic mags some some flexing is normal, but printing in a more rigid filament can't hurt. eSun Pla+ was the baseline print material, though PC or nylon would be better (more rigid). Critical dimensions to check on your print: Front and rear inside flat faces should be 30.63mm apart as modeled. 30.6mm is more or less ideal as the rounds are actually turning (requiring more room than the nominal dimension) as they transition from the single feed down to the double stack body. Print orientations: Mag body - The bottom lips flat on the build plate. Support will likely be required in the mag catch slots, but anything else is extraneous. Follower - Orient the largest flat face on the under side flat to the build plate and enable supports. Spring base - Orient with the button that locks into the base pad up. Enable supports. Base Pad - Print with the "ears" pointed up. Shouldn't require supports at all. Advice: -Some sanding may be required on the inside faces of the mag body and the outside faces of the follower that contact the body. This is largely tied to your print quality. -If the mags bulge too much to fit in smoothly, squeezing the mag before you insert it can help. -If the mag doesn't latch in, check that you removed all of the supports from the relevant cut outs. -Given some variation in manufacturing, if your slide stop lever is hitting the upper sides of the mag, some light sanding of the mag body can bring it back down so it doesn't interfere. If this is happening you'll experience slide lock with rounds still in the mag and you'll see shiny spots on the upper outside of the mag. But again, this has a lot to do with your print tolerances. Springs: These mags are compatible with Sig factory springs or clones, Glock or ETS springs. On the Glock and ETS springs, you'll probably have to bend out the very bottom leg of the spring to fit around the base. Print solid. As always, the step file is included for you to work on yourself if you so desire. Happy shooting and make the signal stronger.
