Aint my first rodeo. If you haven't had a ruger pin walk your either shooting light loads or just haven't shot enough. Ive owned probably over 30 big bore rugers over the years in 41, 44, 45colt 475 linebaugh and 500 linebaugh and just about all of them with heavy loads had the pin walk. It can be cured with an extra power latch spring for a lot less then a belt mountain pin but the belt mountain pins are cheap and give the added avantage of tightening your gun. Have Linebaugh, Hamilton bowen, dave clements, Alan harton, or about any other custom guns smith build you a ruger and its going to come with a belt mountain pin. Why? Because there well worth the small added cost. I can guarantee you and would bet you 5 bucks against my house that if you had 50k through your super it would have had the base pin walk at one time of another. Maybe if your idea of shooting is a box of ammo every 3 or 4 months or spending 25 bucks is going to mean the difference in feeding your family or not it might not be necessary but ask ANY experienced big bore ruger shooter or custom gun builder if its a waste of money and id guess youd just get laughed at. But then I probably don't have the vast experience you do.
