The Jennings takes more grief on TFL than anything else ever built, that's for sure. But I've got one and it's not the worst, most problematic handgun I own. That would probably be the Taurus PT-22.
Line 'em up: Jennings was $59, Taurus was $169. Both of them jam somewhat often. The Taurus is likely made from better materials. The nickel finish on the Jennings STILL looks new even though the pistol is about 15 years old. The 5-year old Taurus' finish looks like it was repeatedly drawn from a sandpaper holster. They shoot the same cartridge and the Taurus holds one more, but can't fit a pocket nearly as well as the slimmer, shorter Jennings. The Taurus has the flip-up barrel and a safer double action only setup, but the trigger pull is terribly heavy (smooth, however.) The Jennings has a decent trigger for what it is, but I wouldn't carry it with a chambered round. The Jennings' magazines are small and can't be taken apart, but they fit the pistol like they were built specifically for it. The Taurus magazines fit like some guy was handed a piece of sheet metal, a hammer, and a pair of tin snips and was ordered to make a magazine under duress.
Both pistols were very nice looking when new, but the Jennings which is 5 times older still looks new while the Taurus looks like it's been through the ringer.
I'm not naive-- I'm confident in the idea that the Taurus PT-22 I have is not one of their finer examples, and I'm even more confident that the Jennings that I have (circa '92) is one of the best that they built.
I'm also confident that if all the posters who bash the Jennings repeatedly had MINE, they would also believe that they had one of the finest examples.
There's no way that my Jennings is half as bad as what I read from folks on here. This pistol is worth every penny of the 5,900 pennies I paid for it.
