I acquired a used P11 at a GS quite a few years ago, shot it a few times for function, and immediately tore it down to smooth up the frame rails and slide because of the notchy, gritty feeling. I also did a job on the feed ramp for good measure, but left the trigger alone as it obviously would never be a target pistol. It always pulled low-right for me no matter what technique I used. I chalked that up to the very heavy trigger pull. It was always reliable, though, with never a failure to feed, fire or eject, eating whatever I ran through it. It was reliable enough that I used it as one of my EDCs. But I also realized it's limitations.

I agree fully with RWSMITH that 5 yds. is about it for decent accuracy. You CAN fiddle with the trigger group to lighten it quite a bit, but why bother? I bought the KelTec knowing full well it's purpose.

It was strictly an up-close-and-personal weapon that went BANG for me no matter what.
