This thread resurrection reminds me I haven't taken my J22 out and shot it in 2009. Checked my records. I bought my Jennings J22 back in 1988.
Reviewing threads trashing Glocks, 1911s, S&Ws, Colts, makes me believe that there are folks who can't clean or maintain or do routine repair or adjustment or pick the right ammo for their gun, and trash the make and by extension any owner who has found one usable, whether it's Jennings or Glock.
That said, if lost in the woods, I would rather have my Ruger MKII, for self-defense my H&K USP. Buying one gun, and one gun only, without range test, I would pass on the J22. I took a chance and got one that has worked well for about 20 years of about 24 to 30 rounds a year. I lost count after putting 10,000 rounds through my Ruger.
But to actually get around to answering the opening post, I copy the user's manual:
DISASSEMBLY:
The pistol must be in unloaded, uncocked condition before take down can be performed.
To remove the Slide, use a blunt object to push the take down button, located in the back end of the Slide, forward until it stops (about 1/8 inch).
While holding the take down button depressed, gently lift the Slide away from the Frame until it stops.
Release the take down button gently as it is springloaded.
Hold the rear of the Slide up and push the Slide forward, off of the end of the gun.
This procedure removes the entire Slide Assembly and is sufficient for normal cleaning and oiling.
Clean the Barrel within a reasonable period of time after shooting.
After the powder residue has been removed, give the Barrel bore a light protective coat of oil.
ASSEMBLY:
Make sure the Recoil Spring is over the barrel.
Place the Slide Assembly overthe Barrel and pull rearward until it can be
dropped down onto the Frame.
Depress the take down button into the Slide far enough to allow it to drop into its slot.
Release the take down button after Slide is pushed down into the Frame.
You should not be able to lift the rear of the Slide away from the Frame if properly assembled.
After the assembly is completed, but before loading, manually operate the pistol to see that everything functions properly.
The takedown button is a cap over the striker spring and you have three parts within the slide: takedown button, striker spring and striker (firing pin). The instructions presume they will be left in the slide. Har har. You may as well be prepared to take them apart, clean them and their tunnel in the receiver too, and reassemble them to the slide.
ADDED: Clean the face of the slide: use a bamboo skewer and q-tips with cleaning solvent and remove dirt and residue from the breech face of the slide, especial the cutout for the rim of the cartridge. A toothbrush also helps in removing residue from the breechface. Also pay attention to the feed ramp leading to the chamber.
