I get why the OEMs are polished to the level they are but I want to shoot mine not put it on a pedestal to admire. I think 100g sanding then some linseed oil on the front strap and back edges will make them more grippy. I want to try to take a deer this season with it and is why I am grip shopping.
Honestly, I didn't have the presentations on long enough to try speed loaders. I have HKS and they work with OEMs and .357.
I disassembled mine to clean and lube before the first shot and found the same on the lock screw. Make sure you lube the crane pivot well. I have read some instances of the crane locking/binding up and believe it is from galling. Mine was completely dry inside.
Black presentations are gone.
