i have a buffalo arms model 1 .357 magnum chambered over under derringer

that i am having a few problems with, the gun is a bit older made in the late

70s early 80s, the fderringer only shoots the top barrel for some reason and

it wont shoot the bottom one, both firing pins move fine but when you cock

the gun then shoot the top then cock it again it wont switch to the bottom

barrel, ive taken the grips off to try to examine why it wouldnt engage but i

only have a general idea, is this something i could perhaps fix easily or should

i take it to my local gunsmith, i like th gun very much and want it to work

100% if i have to depend on it, please give me some positive feedback,

thanks all!
 
Sounds like the firing pin isn't rotating.

If you don't see anything that looks wrong inside of it then I would give it a good cleaning internally with some Gun Scrub. May just be gunked up from time/dust/dirt. Happens fairly often.

After a good cleaning and light lube test fire/function check it.

If that doesn't fix the issue then take it to a smith.
 
hey ohen cepel, thanks for the advice i know a fair amount about firearms

but this one had me stumped, its still not working 100% after i did that but

perhaps someonelse knows something i can do to get this thing working

correctly before i have to take it in?
 
well i had it somewhat working and then about 2 minutes ago i was test/dry

firing it some more and the hammer broke in half, is it possible for a trained

gunsmith to fix this for me considering parts are nearly obsolete for it? coul

he possibly weld it back together? as i said i like tis gun a lot and would like

to have it in as close to 100% shape as possible...
 
haha, thanks guys, yea im a bit impatient sometimes :o....anyway its going to the smith today and i'll see if i can tell everyone the verdict......
 
yep, got myself a new paperweight

don't give up so fast!
like bill said, most likely repairable.
cobra derringers are a knock off of yours and plentiful. i bet some parts are interchangeable with some basic fitting/mods.
if not, a new part could be fabricated pretty easily, as long as you have the original for a pattern. worse comes to worse, parts can be welded, machined and heat treated to be good (or better)as new.
theres a few folks here that can rebuild your derringer in a reasonable time frame. i'm confident it can be done, but i couldn't even look at it for 3 months, just way too busy right now. pm me if you can't find anyone else.

btw, i'm retired and do smithing more as a hobby now. hence, i usually charge only what it costs me. right now i'm building 1911's, which is why the 3 month wait.
 
hey dream weaver and bill, thank you both very much! that makes me feel a

lot better about the gun, and bill i will probably have to get back to you

about what the derringers hammer is made out of because im not 100 % sure

right now but i will let you know most definatly, and like i said thanks for the

interest/support!
 
also the lock up is quite sloppy and if that can be fixed it would be much

appreciated also, i will try for pics as soon as i can as well
 
i believe just from my personal experience it cold rolled leaded steel, im not

100% positive, but i know its not heat treated.
 
yes the magnet was attracted to it, and if it can be repaired it would be

much appreciated, and a weight off of my shoulders
