To put it bluntly, if you pay more than $100 for one, you're being ripped off. Even $100 is a bit generous for a Jennings. Simply put, they are junk. If someone came into my shop and tried selling me one, I wouldn't even give them the time of day for it. At a gun shop, they typically sell for between $75 and $125, based on wear and condition. It's doubtful that shop paid more than $50 for it if they bought it from an individual.
Yes, a Jennings J22 will fire without a magazine inserted.
That's a task best left to a gunsmith.
To clean a Jennings J22 pistol, first ensure the firearm is unloaded and the magazine is removed. Use a cleaning rod and patch to apply solvent to the bore, scrubbing it with a brass brush to remove fouling. Wipe down the exterior with a cloth and use a toothbrush to clean hard-to-reach areas. Finally, lubricate moving parts with gun oil and reassemble the pistol.

.22 LR rim fire
They were about $60 new, and now about $100 in good condition at a gun show.
$50 to $75. These were very crude, low cost firearms of no particularly high quality.
No, a magazine for a Jimenez J22 will not fit a Jimenez J25 pistol. While both pistols are manufactured by the same company, they are designed for different calibers and have distinct magazine dimensions. Therefore, using a J22 magazine in a J25 could lead to feeding issues and is not advisable. Always use the correct magazine specifically designed for your firearm model.
The estimated value of a Jennings model J-22 pistol is between $80-$150 dollars depending on finish and condition. They are becoming more rare and are going up in value rapidly. They are a part of the Ring of Fire pistols and have a unique place in history as the original "Saturday Night Special", which may ultimately make them a must-have with collectors or "mouseguns".
