Easy disassembly
After disassembling my P-3AT a dozen or so times, I finally found what must be absolute easiest way to do it.
I put my left thumb 3/4" below the serial number, my left middle finger against the barrel, squeeze just a little to move the slide back about 1/8" or so. While holding it there, I use a fingernail on my right hand to slide the assembly pin out as far as it will go real easily -- about 1/32" or so. I then use a screwdriver in my right hand to put one side of the blade behind the shoulder on the assembly pin, and rotate the screwdriver until the pin snaps by the spring, then use my right thumb and index finger to remove the pin. Sliding the slide forward off the frame is no problem.
I can't imagine an easier way to remove the assembly pin than this. Try it -- you'll like it!
I usually remove the recoil springs (190,191), recoil spring guide (105), and recoil spring catch (104), and put them safely aside where they won't get lost. If I plan to do much, I would also remove the ejector (115) so it won't fall out unexpectedly.
To put the assembly pin back when assembling the gun, I also use the same hand hold to slide the slide back about 1/8" and the pin goes right in easily.
