Check out this web site for your answer. http://bryco-jennings-jimenezarms.com/index.html If your question is, does Bryco model 38 or model 380 have a firing pin....then yes it does or when it was made.
Since Meriden stopped production in 1918 the firing pin will have to be made. The model 15 was made from a savage patent so you might be able to adapt a firing pin from an early model savage rifle. I saw a picture of the model 15 on the web and it looks a lot like the savage model 29 that was made in 1929-1933.
You can find a replacement firing pin for a Stevens model 87D 22 cal rifle at a gun dealership. You can also find it by contacting the manufacturer.

No. Later (and current) Model 94's have a rebounding hammer.
A good gunsmith can do it.
