Finally after long, long wait, I have made it to the Open Range this past Thursday. It was a great day, qualified with both department and my own rifle, shotgun, and all of my Glocks - G35, G23, G27, G21. It was good shooting, and good times. Then I put all of my guns away, and brought the blue box out. Just wanted to function check my Colt 1991, I got in April. Just as I loaded the magazine, and was ready to let er rip, our Crime Scene guy pulled up in his van and asked our assistance. So happens that he needed to photograph/observe/study some bullet holes [entry and exit] as well as test the soft body armor stopping capabilities, as well as the deformity of the bullet upon impact. Who am I to say no. The victim - average sized mannequin, made out of fiberglass, with hollow inside. The soft body armor, two layers side by side placed behind the mannequin, to catch the bullet. First round ever fired out of my new Colt 1991 was a Federal Hydra Shock and it looked like this on the way in: The way out [sorry for the quality of the pic]: The reason for the exit hole being not much larger than the entry is because first of all, there was only air inside of the target; secondly the hollow point of the projectile got plugged/stuffed/filled with the fiberglass of the first [front] layer of the mannequin, as seen on this picture: The mushrooming, or should I say flattening of the projectile did not occur until the projectile hit the soft body armor and was actually stopped. BTW none of the projectiles we fired that day: 9mm, 40S&W, 45ACP and 44Magunm, made it past the first layer of the soft body armor. Over all on that first and only [up to that point] round, the Colt performed flawless, great action into battery, BANG right on que and ejected the spent casing just fine, over the shoulder and away. I am fully satisfied with my purchase, it has been 100% so far, it receives my Gold Star of Approval for CCW or Open carry Just kidding. I shot a box of 50 rounds afterwards, testing the functionality of the weapon and its cooperation with Chip McCormick Power mags. All went well, couldnt be happier with my acquisition, but then again what would you expect from a Colt.
