At that point get a bigger pistol.

Small pistols really require a bit of technique to shoot them. A positive is that it should improve you large pistol handling.

I hate my keltec p3at but I do occasionally put several mags through it. Last time I ran a box of copper SD ammo through it to check reliability and drew some blood on my trigger finger. With that pistol grips don't seem to make any difference its so small.
