Reloading for 9 mm Stoeger Navy

Every one of your problems is usually caused by the charge being too light to cycle the mass and springs of the gun.
How does the recoil of your loads feel compared to factory ammo of the same bullet weight that does cycle the gun? If it feels lighter, then you may up the charge.
If you are shooting outdoors, does factory ammo throw the case further than you reloads? If so, then you may up the charge.
Beyond that, there are two ways to go: faster powder for a quicker/shorter recoil impulse or a slower powder so you can generate even more powder and longer pressure curve to cycle the action.
Of, as Sieger says, stay with what works...

I don't own a Stoeger Navy Luger, but do own originals and a Mauser Parabellum in Navy configuration. I am a shooter of all of my Lugers, and also a handloader. That said, I own a mixed parts shooter Luger that pretty much refuses to shoot my reloads!! I have been a handloader for more years than I want to admit to, and load for all of my handguns......except this one Luger.

I have tried 115gr and 124gr of different configuration bullets, Bullseye, Red Dot, Unique, Power Pistol, etc. powders, with only partial success for this one Luger. If I feed it PMC 115gr FMJ, it is soooo happy!!

My best handload for this problem Luger is Remington 115gr FMJ with 5.5-5.6gr Unique loaded long....1.160-1.165 OAL. This load will function reliably 80-85% + of the time. It functions 100% of the time in all of my other 9mm handguns.

Many Lugers are ammo sensitive(spring sensitive and mag sensitive), so if you found ammo that your Luger likes....feed it that!!
