I'm not "naysaying it," I'm questioning its necessity or even its benefit on a gun that doesn't need it. On a 2 inch barreled scandium 44 mag? Sure. On an 8 inch barreled N Frame 357? You might want to see your doctor if you need that.
Considering the very real damage it could do to your ears (more so than normal gunfire reports), I don't see the use. I have a Model 29, stock grips, 8 inch barrel, and the recoil is lively but manageable. I wouldn't dare have someone butcher it and make it twice as loud.
