The Shield Arms Handgun Magwell for Glock 43X/48 (brand part no. G43X48-MAGWELL-BLK) is built to speed up reloads by funneling the magazine into the grip instead of forcing a shooter to hunt for the well under stress. Shield Arms machines it from billet aluminum and finishes it in a Type 2 anodize for corrosion resistance and a durable, low-maintenance exterior. The contoured shape is designed to work hand in hand with Shield Arms’ own S15 magazine and S15 +0 base plate, adding real grip surface without changing how the pistol feels in hand. Made in the USA, it’s a straightforward upgrade for a Glock 43X or 48 owner who wants faster, more confident reloads.
