Havent had a chance to inspect a G2 but I'm thinking that they are a bit similar to the Encore. The full lock release is on the RH side of the frame inside, if the locking lugs arent fully engaging it won't push it back enough. Use a elmarko on the lugs and close the action to see how far they are engaging. Should be about half way. If not that may be the problem. As I said I am not positive on this but if it's similar to a encore internaly that could be the problem. Just something to check.
