When I first saw Glock’s announcement of its new Glock 47 handgun, I was totally confused. I initially thought it was a variant of the long-slide Glock 17L or Glock 34, but after handling one at SHOT Show, I realized it was the same size as the 9mm Glock 17. In fact, it was nearly identical to the full-sized Glock 17. The only aspects of the gun that gave away that it wasn’t just a Glock 17 were the shorter dust cover and the extended portion of the slide covering the recoil spring.
