Glock 43X/48 – Magazine Extension – +4 Capacity – Fits OEM 10-Round Magazines
PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.
Tyrant CNC’s +4 magazine extension for Glock 43X and Glock 48 pistols is built for shooters who want more onboard capacity, faster reload handling, and a cleaner grab surface at the base of the magazine. This extension is designed around factory Glock 43X/48 OEM 10-round magazines and includes a higher-power spring for reliable function with the added capacity. Available options are organized below under Variants.
Fitment
Fits Glock 43X and Glock 48 OEM 10-round magazines.
Does NOT fit
Does not fit double-stack Glock magazines. Verify compatibility before purchase if you are using non-OEM magazines or alternate base pad setups.
What it does
This extension replaces the factory base plate and adds 4 rounds of 9mm capacity while also giving the magazine more weight for cleaner drop-free reloads and a more positive grab surface during manipulations.
Why it’s worth it
More rounds is nice. More rounds without turning installation into a full exorcism is even nicer. Tyrant’s retention plunger design keeps install and removal simple, while the added knurling and machined profile help the mag come out and go back in like it has some manners.
