I shot my SR40C today and I was far from having good results. I have to figure out a different grip because evidently I am squeezing my fingers on the grip while squeezing the trigger. This is causing me 4-6" wide right and a little low. I also noticed the trigger seems to be fairly gritty also. I thought maybe if I could get a smoother trigger and breaking point my shooting might be better also. I checked some past threads here on RT about installing the trigger kits or the ghost trigger. I watched a few you tube videos on installing the kits and one I watched he didn't replace anything. He just polished and lubed some areas. He used graphite powder everywhere that metal moved against metal and he polished the firing pin surface trip point. He said it really smoothed it up and good break as well. So I figured I would maybe just try lubing the metal to metal areas as well as the pin surface. I have an oil called Ultima Lube 11 from Wilson Combat which is the only lube I use on all my guns. Like graphite this oil gets deep into the metal surfaces. I saw a bearing test with this oil and no other oil they tested came close to the protection using this oil. So anyway I lubed any and all points of metal sliding against metal. I reinstalled the slide which was all I removed from the gun to do this oiling. Surprise - surprise holy jumping up and down the trigger has huge improvement on the gritty feel. The trigger break was smooth. I tried using my electronic fish weight instrument to check trigger pull weight with a make shift string to trigger. It was showing 5-7 LB. pull. So all I can say is the trigger feels much better. I am probably not going to kit the trigger. I need actually shoot it to really decide on that though. I am going to shoot another hundred rounds tomorrow to see if it makes a difference in my accuracy. I know one thing I better be careful so I don't have any zingers due to the smoother trigger now. I will update after shooting tomorrow.
