XTech Tactical GX4 +1 Grip Extension Magazine

The middle option between the flush 11-round factory mag and the 13-round extended factory mag. The XTech extension gives the GX4 a full three-finger grip without adding the half-inch length that comes with the 13-round mag, and at $15 OP it costs a third of what the factory extended mag costs.

Capacity is the trade — 10 rounds versus the 11-round flush or 13-round extended. For most carriers, the grip improvement is worth the round count drop since recoil control on a 18.7 oz micro-compact is meaningfully better with a fuller grip. Fits both GX4 and GX4XL since the grip frames are identical.
