When I bought the 625 JM, it didn’t come with the stock original wooden grips so I placed an order online through Jerry’s company Bang, Inc and got it pretty quick. It’s supposed to provide a smoother and flexible purchase on the gun during fast shooting.
Here’s the 625 with the Hogue rubber grips and Jerry’s competition grips side by side about to be installed.
Installation is a snap, just remove the old grips, swap out the stirrups and slide the new grips over.
I do need to go test this grip out to see if I’ll like it. Hope I don’t fumble because of how smooth the grips feel.
