I should but I don't have guts enough to do it myself and don't know where to take it.
I had an SP101 done and it was well worth the $45. Softer lead, gas checks - they worked to a degree but I couldn't shoot the gun to its potential until I had the throats reamed.
I'd do it again in a heartbeat to salvage an otherwise desirable revolver, but I don't know either where to send one these days. I sent mine to Cylindersmith, but he's out of the business.
