Berreta A400 help.

[Halfnutz]

Looking at a friend's Berreta A400 Extreme.
He has sent it back to Berreta twice.
The gun works fine with Federal, but has light strikes with Kent Fast Steel (his preference)

My guess is the the Kent have a harder primer. I found and ordered a JP hammer spring but it is only +10% power.

The firing pin return spring has an o-ring at the base of the firing pin. I considered removing the o ring but am hesitant to do so.

Any other thoughts to improve ignition.

Never had luck with Kent myself. Always use Federal, Remington, or Fiochi.

12ga Kent 3in BBx2 seems to be very popular around here.

I recommend you do a search on Shotgunworld Beretta forum for A400 misfire.

I looked briefly and saw this:

Tell him to contact any one of the three Cole Gunsmithing facilities (Maine, Florida, Texas)

 

[Halfnutz]

Thanks. I've got it at home but I'll reach out to them.

Maine does the majority of the gas gun work/ builds. They’ve been very helpful

Far be it from me to question the makers of fine firearms, but the hammer is ultra light.
The rear of the firing pin has very little protruding out the back of the bolt before the hammer is stopped by the rear of the bolt body.
The firing pin protrusion of the unassembled bolt looks like enough to pierce the primer.

Thanks for the suggestion.
Had a short chat with them today. Nice guy, but not a lot of suggestions, except to switch ammo and check the spring. He was not averse to stretching the hammer spring a little as an experiment.

Hammer spring from JP Custom Products seems to have done the trick with the Kent shells.

Weird.
Have A400 Ext +. Shot Kent Steel last week, no problems. Will be out again tomorrow.

Friend has 2 of them, and neither will shoot Kent Fast Steel. I'll be putting a spring in the second one as well.
