in the 1980's and early 90's, I would buy these "Junk" 25's for $10, and they usually were broken but came with a partial box of ammo. Normally a spring was the problem and Firing pin was #2, repair parts ran $3-5, I would fire 3 shots to verify function and sell for $35 with the ammo. At that price one never lasted past payday!
Also had 2 or 3 left in apartment over the years, I came up with ammo and sold them the same way!
I have only met one person in my lifetime that actually reloaded 25 ACP!
I remember these cheap little guns were everywhere years ago. I would pick them up cheap too, often from some of the poor money managers I worked with. Really didn't run into that many broken ones, many had only been shot a couple times and more than once I got them with a still full box of ammo too. Sometimes sold them back to a guy when he had more money from his latest paycheck left... with a small storage fee so to speak LOL.
The few broken ones I did see usually needed a firing pin or a magazine ...... Some people can't leave the feed lips alone and it's worse if they dropped the mag and stepped on it.
Oh yes, need to add I do reload the little 25. I have a box I set up and shoot through to recover the fired cases, out in the open they are usually gone for good otherwise. My own tastes run to a little higher quality than those old cheapies though. I like classic vest pocket guns like the old Colts, Ortgies, Mauser and others as well as the better later guns like the Beretta.
