Was lucky enough to get my hands on a (Corrected to Glock 17 with a conversion) and tested it at the range. I was expecting extreme muzzle rise but found it very controlable with 90%+ on target. There was some muzzle rise but not as much as expected. At the 7 yard line, we aimed at mid abdomen and the rise went up into the upper chest and neck. If you don't lean heavily into the weapon on the balls of your feet, you will be stood up straight. Here is a video, will take a moment to load.
