I found a P3-AT recently at a gun show that was a total piece of crap! A private vendor said it was his carry gun until he found a HC P3-AT, it was in such bad shape that I wouldn't of carried it! It had a cracked frame, was missing the ejector, assembly pin spring, and the outer recoil spring. The buttonhead screw was stripped, the trigger spring slipped so it wouldn't reset, the blue finish was really bad and had surface rust on the slide and barrel. He said he fired less than 50 rounds with it. He wanted a $100 and settled for $60 ;D Yesterday I tore it completely apart and cleaned everything and decided I would try parkerizing for the finish. I had already ordered the parts I needed and had them in 3 days! Kel-Tec sure has great service. I acid cleaned all the metal parts and water washed them. I buffed all the parts and bead blasted the slide. I picked up some Zinc Phosphate from my plating supply house, mixed and heated it and put the slide and barrel in it for 10 minutes, removed and washed in running water and air dried it then soaked it in 30wt synthetic motor oil for an hour to seal it. I used the synthetic oil because it has Teflon in it, the Teflon soaks in to the parkerizing and adds to the overall durability. I then nickel plated the hammer block, hammer and trigger bar. I sanded all the grip seams and then polished them smooth. Replaced ALL the springs, extractor and extractor spring then added a light coat of grease to the moving parts and assembled everything. I then added my energy absorbing pads and grip cover. I can't get over how smooth the slides and trigger pull is on this baby, It's much smoother than my 2 other factory parkerized P3-AT's and I polished all the moving parts on them also. I think the sealing in the synthetic oil and nickel plating all the moving parts makes this smoother than the factory finish. I went to the range this morning and fired 50 flawless rounds of Speer Gold Dots, needless to say, this is my new carry gun!
