Hey again guys.
so last night I took the spring out of the mag and cleaned the channel as much as possible, then reapplied some oil. This seemed to have cured my problem.
So today I played at the vault with it and I didn’t have a problem. The slide didn’t crack again and the mag didn’t jam up, so I’m very pleased.
thanks to everyone who commented and in aiding me to get this gun working. It’s much appreciated.
