I have an early alloy P14, 4 digit serial number starting with a "1" sort of early gun. It has a little over 30K rounds through it now without a bit of trouble. The ejector is loosening up over the last 10K rounds and should be replaced soon. The slide stop hole is about .0005" out of round too, but I do not know what it was like when I got the gun so I don't know if it is from frame battering. At any rate it is very little wear. I had a trigger job, beavertail, trigger, flat mainspring housing and hard chrome plating done on mine at about 5000 rounds. After that second break-in that I had to do it has been flawless, eats anything you feed it that will fit in the chamber besides 155gr semi wadcutters.
Out of the box it was dead reliable with anything you fed it, and sub 2" at 25 yards with most ammo. The sights as issued on the older ones sucked big time, that is the only reasonable complaint I have seen. If the grip feels big put a flat mainspring housing and a short trigger on it. I have pretty small hands and it is very comfortable to me, more so than a G17/22 size grip.
