MAG SHIELD FITS GLOCK 17 +5/4 EXT BK

Description

The Shield Arms Glock 17 extended magazine with pre-installed +5 extension is built for competition shooters, duty use, and anyone who runs a full-size Glock 17, 19X, 34, or 45 hard and wants to spend less time reloading. The foundation is a genuine Glock OEM magazine body, so feeding reliability stays exactly what it would be with a factory magazine — no tuning, no break-in period. Shield Arms machines the extension from aluminum and anodizes it, keeping added weight minimal while giving the grip a secure, defined surface where the hand indexes at the bottom of the magazine.

The extension arrives factory-installed, so there is nothing to press-fit or torque down before heading to the range. Where this design makes a practical difference is in maintenance: the floorplate is designed for quick removal without pulling the extension off the magazine body first, which means spring and follower inspection or replacement does not require disassembly of the whole assembly. That matters over a long service life. The magazine is covered by Shield Arms’ lifetime warranty and a Spring for Life guarantee, so replacement springs are not a consumable cost the shooter has to track. Manufactured in the USA.
