Colt Mustang 380 MK IV series 80 question
Where are a list of serial numbers so I can find the age of this gun.
Where can I find a diagram of its innards?
I want to change a firing pin spring I got for it.
I just love to shoot this pistol.
It is used of course.
It failed miserably when I got it.
I put a full length guide rod and single stack springs in it the other dayl.
I have shot it about 200 times with no failures.
2 of my magazine do not stay open on empty.
Thanks
Earl
