NRA bullseye shooters have been arguing for years, nay decades, over frame versus slide mounts. Frame mounts work with the loads set up for iron, but give away some potential accuracy in trade for a much longer working life. On the other hand slide mounts require heavier loads and springs, but give a potential small increase in accuracy, BUT the gun has to be fitted exceptionally tight in order to realize it, and they do seem to wear slightly faster. No worries about the optics if they are Ultradot or Leopold extended relief scopes they can handle the shock levels. The other benefit to slide mounting is a lower sight line which some competitors regard as important. Go with whatever floats your boat, but changing from one to the other may not be worth it especially as the OP's gun would need a slide tightening job.
