I've just received my SA back from the factory and am more than happy with it. When they reworked the thumb safety and tightened the frame/slide fit, they did great and now the gun is as it should always have been.
I did contemplate putting in a standard GR, but I think I'll stay with the 2p FLGR. I've found that it doesn't take any longer to disassemble than anything else and does seem to make recovery time shorter.
All I do to take the weapoon down is lock back the slide and unscrew the end of the GR, which is never more than hand-tight. Then the slide is slowly let down and I use the end of the GR to depress the plug so I can swing the BB out of the way. It goes very quickly.
I have been considering adding a new bushing simply because the factory one looks weak. Of course, a stainless or chromed bushing would highlight the bore (good psyops), but I wonder about the fitting required and if I could do it myself. I don't want something so tight that a wrench is mandatory for field stripping.
