I have/had the same complaint as others have posted - the trigger & guard really bit my finger. *I sanded both the trigger and the guard down and then bought the trigger shoe from Kel-Tec. *I had heard that the shoe does not fit the P3AT, but Kel-Tec specifically lists it for the pistol, so I decided to give it a try.
The shoe leaves a good bit to be desired for the price. *It fastens to the side of the trigger with two tiny set screws, which are supposed to "drill" into the trigger when tightened. *I found that one of them actually compressed and deformed the trigger, due to its small cross section, rather than biting into the trigger. *It certainly did not fit securely! * >
I took the shoe back off and drilled two tiny holes in the side of the trigger to receive the set screws, then super glued the shoe to the trigger and tightened the screws. *That seemed to help. *We'll see if it holds up.
Anyone else tried the shoe with their P-3AT?
