Hello everyone I recently bought a gen 3 sub 2000 in 10mm. I took it to the range and put 200 rounds through it and the only issue I’m having is when I’m chambering the first round and I pull the bolt all the way back and let it go about 50% of the time it won’t go fully forward and I’ll have to tap the bolt like a forward assist to get it fully seated. Same thing if I lock the bolt back and slap it mp5 style it fails to fully go into battery basically 100% of the time. Just looking for some advice or tips if this is common or If the gun just needs to be broken in more. Thanks for the help!
