The 100 round challenge is a function test I came up with a while ago to see how well a gun would operate if you got it, well pretty hot. Shooting 100 rounds through a pistol as fast as you can load is a good way to do that, and it can also be a fun test of your endurance. Here’s video of the me running the Springfield Armory Range Officer through the 100 round challenge…which it failed.
At 3 minutes into the video I experienced an unusual malfunction, where the gun returned partially to battery, but not all the way. When the trigger was pulled, the hammer fell to the half-cock notch, causing me to believe I’d had a light primer hit. It wasn’t attended I attempted to clear the gun and it was locked up tight that I realized I had something else entirely. The round in question had the correct dimensions, and successfully chambered and fired after clearing the gun. This was the second time that range session I’d had issues with the gun not returning to battery. After conferring with a well known 1911 expert, he let me know that this problem is commonly caused by a slide stop that isn’t quite correct, and the best fix is to replace it immediately. I’ve ordered a new slide stop from Brownells, and as a precaution some additional recoil springs as well.
However, because this is part that needs to be replaced at the armorer level; it is a -5 deduction for the gun. That brings the 1911 RO’s current score down to 78/100, which is still a respectable C+. With just a bit over 500 rounds left in the test, we’ll see where things go from here.
