Get a KKM barrel and load up some 45 super.  A 255 gr bullet at 1025+ fps  is nothing to sneeze at.

Bayan, Dawson Precision MOS height sights are what you are after.  You can use them with a RMR or other red dot sight installed.

Well known issue.  The fix is to install an Ed Brown 10/40 slide stop.

13.2 gr AA #9
Starline case
CCI 300
200 WFN from Accurate mold
1.240" OAL

Should get you 1250+ fps from the G40 or Fusion

I remember reading about a guy who had an issue with premature slide lock in his Remington R1 Hunter 10mm.  The fix was to install an Ed Brown 40/10mm slide stop.

Maybe it's an issue with the Ruger slide stop and certain bullet profiles?  I'm thinking Hickok45 knows how to shoot a 1911.
