I am not looking to change up this gun a whole lot but I am probably gonna refinish the slide and frame with Black Gun-Kote, eventually. What else would be a good value upgrade? I was thinking of getting maybe stainless barrel bushing, recoil spring plug, slide stop, and maybe even safety. Would that look lame? Is the safety easy to replace? I want it to maintain the current grip safety and a spur hammer. The grips are fine although I might want some thinner grips in the future. What else would be a good value upgrade on something like this?
