    Awesome Glocksome

    My Glock came with three (15) round magazines, four backstraps, a cleaning kit and case. With a six inch barrel, I am guaranteed maximum velocity. I have yet to shoot this new pistol, but it fits well in my hand, and I have yet to try any of the four backstraps that came with it. I am pleased with this purchase, and ensured that I will be "bear safe" in the future.
