In the beginning I only shot Belom 124g and everything was fine, so I thought my CR920 was pretty reliable. Turns out those are the only ammo that works fine. Then I tried Federal 115g, blazer brass 115g and 124g, pmc 115g, magtech 115g, cheap Turkish ammo… they all caused FTE and FTF.
Today I field stripped my cr920 and discovered that it didn’t have an extractor depressor plunger. Wtf? Is SS a different design? The extractor is also stuck, no matter how hard I press the safety plunger, it won’t budge. Shining a flashlight into the hole where the extractor depressor plunger should go, I saw the screw for my optics, so I’m guessing it doesn’t come with one. So how do I remove the extractor? Does it require removing the optics?
Edit: nevermind, watch a video on MR920 disassembly and they use a short extractor plunger. Disassembling the slide requires removing the optics.
