I recently polished the internals and installed the RRK in my SP-01 Tac. I actually took the gun to the range last week without the screws installed (I didn't have loctite at the time) and the gun performed totally, 100% fine (with S&B FMJ 115 gr).
I later installed the upper and lower screws following the CGW instructions. The hammer dropped fine in both DA and SA. However, when I went to the range today, I had multiple light primer strikes (with the same S&B ammo).
I am dumbfounded. The only diff between this trip and last trip is the installation RRK screws into trigger.
For more context, the gun also has:
13# mainspring, RP FP spring, 14# recoil spring, RP trigger return spring.
I have the RP plunger spring in my CGW cart, but it has never been an issue. Like I said, the gun has performed flawlessly until the RRK screws were installed.
Any insight would be greatly appreciated. Otherwise I'll need to either remove the screws or reinstall the factory trigger...
