Shield Arms S15 Gen 3 9MM 15 Round Magazine and Mag Catch Combo Kit 3 Magazines Includes Steel Magazine Release For Glock 43X 48 Black S15 COMBO G3 3M 1C UPC 850029545811
Product Description
The Shield Arms S15 Gen 3 15-Round Magazine and Steel Mag Catch Combo Kit for Glock 43X and Glock 48 (MPN: S15-COMBO-G3-3M-1C) is the ultimate capacity-boosting package for slimline concealed carry pistols. Delivering a massive 50% increase in magazine capacity over standard factory 10-round polymer mags, this combo kit equips your G43X or G48 with full-size 15+1 round firepower in a flush-fitting profile, complete with the mandatory steel magazine release required for optimal reliability.
Precision-stamped in the USA from durable, heat-treated steel, the Gen 3 S15 magazine features key engineering refinements over earlier iterations. These improvements include upgraded feed lip geometry to optimize round alignment, a durable Black QPQ (Quench-Polish-Quench) corrosion-resistant finish, ambidextrous magazine catch cuts for dual-handed setup, and an impact-resistant polymer baseplate. The included Shield Arms Steel Magazine Release replaces the soft factory plastic catch, preventing the wear, chewing, and retention failures caused by steel-on-plastic friction during hard training.
By bundling three (3) Gen 3 15-round magazines alongside the essential black steel mag release, the S15-COMBO-G3-3M-1C kit provides a complete, turn-key performance overhaul. Backed by Shield Arms' 100% satisfaction guarantee and lifetime warranty, this combo elevates your Glock 43X or G48 into a formidable, duty-grade concealed carry platform.
Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix: Fits Glock 43X and Glock 48 9mm pistols exclusively. (Note: REQUIRES installation of the included steel magazine catch. Running steel S15 magazines with the standard factory polymer mag release will cause rapid wear on the plastic catch and lead to magazine seating failures).
- Perform a complete firearm safety check: drop the magazine, lock the slide rearward, and visually/physically inspect the chamber to verify zero live rounds are present.
- Field strip the slide assembly from the frame to access the internal grip module.
- Use a long needle-nose pliers or armorer's pick to unhook the vertical magazine catch spring from the factory polymer magazine catch channel.
- Slide the factory plastic magazine release out from the frame socket.
- Insert the included Shield Arms Steel Magazine Catch into the frame socket, realign the spring wire into the internal channel notch, and verify crisp spring tension.
- Insert an empty S15 Gen 3 magazine to confirm smooth drop-free ejection and positive catch engagement before loading live ammunition.
