Thanks for the compliment! The grips required very minor fitting around the groove that fits around the back strap. Also, the left panel interferes with the de-cocking function. That isn't to say that quality isn't good, I think the grips transform the gun into something special. I was fortunate that he happened to have this set ready so I didn't have to wait for them to be made. I won't shoot this gun very often, but I enjoy looking at it and showing it off to friends. Everytime the safe is opened, I'm compelled to pick it up.
