If you can't reach the magazine release on your stock Glock, try the OEM extended release. If that doesn't work for you, find a different pistol to work with. Most times it's an adaption. You integrate yourself to your pistol, otherwise it's just messing around. Any time you feel the need to supplement your chosen sidearm with something, you're going in the wrong direction. You may also change your method of operation. Simply put....you want to keep things simple either way. Saving your own skin is rather a simple ordeal.....applying it should never be complicated.
