I had a muzzle break installed by magnaport on my 44 mag srh.To tell the truth I don't think I really needed it. I just figured the more pleasant it was to shoot, not that it was unpleasant before, the better.
They removed the frontr sight, cut the barrel, threaded it and installed the break and reinstalled the front sight further back. I don't like scopes on handguns so I wanted the sight back on.
They did a great job. I can't remember what the cost was but it was on their website. I also had them do an action/trigger job, recut the forcing cone, number the cylinders.
