Having a magazine that reliably drops free can make a huge difference in time on a stage. The SLR Rifleworks +0 California legal magazine extension installs quickly and easily to your favorite Glock factory or ETS magazine for the Glock 17 handgun, bringing your capacity to an impressive... 10-rounds per magazine. However, the extra mass added by the extension helps to ensure that your magazines will drop free cleanly, allowing for faster mag changes. The larger textured base also makes grabbing the magazine from your carrier easier than ever! Machined from high strength 6061-T6 aluminum with a durable hardcoat anodized finish, the SLR Rifleworks Glock 17  magazine extension will even help protect your mags from the drops.
