I suppose it's dependent upon the individual. Some report getting pinched between the step in the trigger at the top and the frame (I don't); some report getting pinched between the top of the finger and the triggerguard (I don't); others feel discomfort or trigger sting or trigger slap supposedly related to the shape of the trigger, the sharp recoil of the pistol or the design or a combination. That's where I am. I shot it back to back with a Kahr PM9, which I love to shoot, and the overall recoil impulse is very similar. However I get zero trigger finger pain with the Kahr and significant pain with the Kel-Tec. This makes the PF-9 FEEL like it kicks much harder but it's all in the trigger. Which is weird. I'll try heat shrink tubing and then try straightening it. If that doesn't work I'll try the aluminum trigger. I like this pistol but it hurts. Tips on the mods?
