Wow you have a great deal of HK's.

Anyway to your question I would give hk a call first thing Monday morning and ship it to them

I don't think hk supports the hk4 anymore. To the OP , I would verify its setup to fire centerfire . It may have been left in .22 rimfire position . ( firing pin changes orientation).

Thank you Sir I will give them a call to see if they will even work on a 1971 pistol they have not made this gun for a long time but it still might be my best bet to give them a try

how do you change it to center fire from rim fire it did have the 22LR barrel in it when I got it

 

[sean415]

Yeah I was wondering that too but you never know they might be able to give advice.

What does the primer look like what kind of bullets are you using, if the firing pin is hitting the primer and barely putting a dent in it it might be the spring, try using federal ammo I hear they have the softest primers for very light hammers.

 

[nat91683]

It don't hit the primer I think it is in rim fire mode and I think I need to change it back to center fire

That's why it is not firing.

This manual will help. Page 13. Check face plate orientation. Currently probably "R". Needs to be rotated 180 to face "Z". They are great little pistols . I enjoy mine.

Yes the gun was on the R side I'm changing it to Z now I can't wait to try to shoot it again tomorrow thanks to everyone for your help

They shoot pretty good with .380. Watch your grip, beaver-tail not large enough. mine has bit me before. (not as bad as early ppk) I've shot a handful of 380 through mine. i would suggest using ball nose ammo in it, truncated or flat nose it was pickier with. I enjoy shooting it in .22 the most.
