With a round in the chamber and putting in a six round magazine it does not allow it to fully lock in. I attempt it to use different ammo thinking that that might be the problem but it does the same exact issue. I bought a new magazine thinking that that would resolve the problem, but it's still occurring. Any suggestions?

I have updated my 2017 iMac 5K already to 15.7.5 and want to know if the update will work.

Thank you in advance!
