Hello all, its been a long time. I just bought a brand new heritage rough rider in 357 magnumto on an impulse. I got it home, cleaned it all up. The cylinder locked up nice in both the hammer down and full back position. Well I took it out today and shot it about 20 times. Now my cylinder will move around alot in the full down position and slightly in the fully cocked position. Is this normal or do I need to do some work to it?
