Hello Roger,

A magazine that will work in a Dura-Matic or Model 80 would not be a magazine that was originalto your Model H-D Military. Note the Dura-Matic used a pocket in the left side of the magazine to retain the magazine.and not the heel of the magazine.

As to Springs, only the driving spring might need changing.

Checking the firing pin for what?

Are you using a original finger style magazine?

Failure to close is often associated with a dirty chamber - looks clean but isn't really-, a dry fire ding in the chamber mouth, excess lubricant on the bullet, or a pad driving spring.

            Good evening John, My magazine looks like the left one in your picture. So I guess I need to find a magazine. Any ideas where I can get a magazine and where would you suggest I look for a driving... more

              Wolff gunsprings.com sells the spring you need for your pistol. Be sure to cut the spring to 40 coils before installing it. Original magazines can be found on eBay from time to time. Expect to pay... more
