Hello. I recently got a model 29-2 44 mag. It's blue with a 6 1/2" barrel. It's pinned but, the cylinder is not recessed. The serial # is N128***. Any ideas why the cylinder isn't recessed? Maybe the cylinder was replaced? Were there earlier model cylinders that weren't recessed that could have been used on this gun? Also, it has 3 screws. Any help is greatly appreciated!
