Beats me. I'm not enough of an engineer to say anything more than the article says. And even then, I wouldn't attempt this on a dare.some of this is similar to what i did to my Intertec Cat45 to lessen the stacking and the trigger pull was much improved.
but on the p11, will this improve (shorten ) the reset lenght of the trigger? that is where i want improvement. with my finger size, to insure reset i pretty much have to completely release the trigger until my finger taps the back of the trigger guard
