“The 870's production for over 30 years had a design whereby a user could fail to press a shell all the way into the magazine when loading - so that the shell latch did not engage the shell - which could result in tying up the gun. This was caused by the shell slipping out of the magazine under the bolt in the receiver to bind the action, requiring rough treatment of the action or even disassembly. The potential issue was resolved with the introduction of the "Flexi Tab" carrier. Guns with this modification can be identified by the "U"-shaped cut-out on the carrier, visible from below the gun. The cut-out, combined with a modified machining on the underside of the slide assembly, allows the action to be opened with a shell on the carrier.[15]”
Interesting. Given the added QC on the PMag guns not sure if this was an issue.?? I taught and ran the PMag for 15 years and other then some failure drills I don't recall this ever happening on our Patrol 18" or 14" entry 870's......could have just been luck. Thanks,
