I have two Rival-S Darksides which I shoot in USPSA. I use TF +4 mag extensions. Mods are: FS trigger, W42 guide rod, 15# Colt Commander recoil spring, Glock FPS plunger spring and have the split ring fix. I have about 4,000 rounds through each. From day one, on chambering a loaded magazine (147 gn RN 1.125 OAL), the bullet will get stuck on the feed ramp and require a tap on the back of the slide. Otherwise, I've had no issues until recently. One pistol has started to lock back on partially loaded mags. I contacted Century and requested replacement mag catches. They have asked that I send the pistol to them and are willing to look at the other as well.
I'd like to know what experiences people have had with Century's service of problematic Rivals - especially mag/feeding related issues. Specifically, did Century resolve your issue(s)?
