I found a drawing for the 603 so i see how the slide fits onto the cocking linkage, i was thinking about attaching a wee rod to the same place on the linkage but coming straight out the bottom and hiding it in the accessory rail.
With the baffles fitted i can cock and fire it's so quiet so dry fire isn't such a priority now but it would be easier not to have to cock it properly every time.
Still undecided on refinishing the stock or not, i was thinking about stripping it and giving it an oil or wax finish with some stippling on the grip, its a bit smooth as is.
