The puma medallion on mine fell out about the second range trip. I have no idea where it is now. There's sort of a hole where it once resided. :laugh: Mines from about 1987.No photos handy, but I have two - a 357 and a 44. Both 20" barrels. The 357 is old enough to still have the Puma medallion.
From what I've read the velocity gains from longer barrels pretty much end somewhere around 18"-20" so I chose the 20" barrel for both of mine to keep them a handy length but still get max velocity.
