Sig MPX 9 Magazine Loader

thingiverse

Team Scorpion Evo has enjoyed a slight advantage in the competitive world of 3D printed SBR PCC aftermarket accessories with replacement magazine floor plates - until today! Introducing the integrated clip and spoon speed loading system for the MPX! Featuring Xtreme "clip" asymmetric chamfering to make sliding into rows of rounds painless, even on tightly packed ammo boxes. Additional chamfering at the end of the clip facilitates quick loading of cartridges into the clip. Edge blends inside the "spoon" assist in printing vertically (recommended orientation). More chamfering on the edge of the spoon makes it easier to jam onto a magazine. Compact and smooth, with flat surfaces for logo remixing! Why fumble with hand-loading cartridges from factory packaging when that same packaging sets you up for quicker mag loading with this system? Be the envy of your friends, fill your mags at the range before they can reload! The "LDRCF" version features my school centerfire rifle team's logo. I shoot my new SBR at 2-gun, hoping to replace my conventional AR-15 in 5.56x45 with a cheaper solution for matches under 100 yards. Print Settings: Printer: FFCreat0r Rafts: Yes Supports: Doesn't Matter Resolution: 200 micron (or better) Infill: 100% Notes: Print "LDR_MPX_9_1.1.stl" at above settings, picture shows recommended print orientation. I recommend ABS for outdoor use and scaling for shrinkage. Finishing: Review of terms: Magazine - a container holding multiple cartridges; Clip - the part of the system guiding cartridges into the magazine; Spoon - the part of the system used to insert cartridges into the clip. Allow the item to cool evenly if using ABS. Remove the raft. Try to cut so that it is as wide as possible at the case rim, then notch out the rest. Use a spent brass or steel case and cut it in half to create a finishing tool. Cut a slit to remove the half. Resist the urge to sand/file it; you want it sharp and nasty. Hopefully, it's still hot from friction; if not, reheat with a blowtorch. Use needle nose pliers for a nifty finishing tool! Don't have a spent case? You can try scraping out the pathway with a knife or shove rounds through while disconnected to wear it down. Using a spent case as a cutting tool works better and is simple. Usage: Slide 5 cartridges in, straight from a row of a box of ammo (or single load from a bag). The biggest efficiency improvement comes from conventional 50 round box packaging. Ram them in using a hard surface like a heavy table or railing, trying to push up for the curvature of the mag and keeping the inside flush with the mag lips. Push from the mag slightly upwards, applying downward pressure with thumb. I had difficulty loading to 30 rounds but it works beautifully at 20-25. I'll make V2 with a way to keep it flush on the feed lips and a longer guide to stop cartridges from peeling out when under force.
