Now, my Glock 17 is old, at least as Glocks go, with a serial number that dates it to 1992, but the recoil spring assembly is fresh, having been prophylactically replaced...*checks logbook*...428 rounds ago.
It's been running fine with the Blazer Brass, but how would it deal with this dregs of this defective lot of Fiocchi? (And I do mean defective. The velocity spread between the fastest and slowest rounds in a ten shot string was a full hundred and five feet per second.)
I ran the target out to seven yards and did a bunch of single shots and fast three- and four-shot strings from low ready with the Blazer Brass, before sending it out to fifteen yards to shoot at the upper A-zone with the Fiocchi.
The Fiocchi ran the gun fine. I wish the same could be said of me, but it was hard to make out the head box at 45 feet. I probably would have done better on a traditional bullseye, or even a free-standing USPSA target.
The CAP sights are such an improvement over the factory Glock sights, especially for shooting fast.
