Did you ever decock the hammer while disassembled and have the it hit the plastic? I actually didn't pull the trigger but instead pushed the hammer back while cleaning the lower to try to get it lock. I didn't push it far enough for it to catch. Instead it went flying forward when I let it go. OUCH! It's a polymer to polymer hit. Will this hurt the lower receiver and hammer?
Everything looks fine though.
