Q: My barrel locks into place sometime and I can't get it out without taking the gun apart. how can I fix this?
A: The twist lock groove on the barrel is made a bit deeper at the end to keep it from slipping out of place. On some guns the twist lock assembly locks in there. Just take the gun apart completly. The twist lock assembly is a small part that fits in the front of the trigger guard. There's an allen screw at the bottom. Find a key that fits and loosen it a bit. this makes it easier the push the pin down and the barrel shouldn't lock anymore.
