Benelli 95 dry fire bridge or plug

Post by davidbullseye on Wed Oct 31, 2018 10:02 am

Hello, 

Benelli experts.

I have a 95E .32 that did not come with either the red dry fire bridge or the chamber plug.  

I made a bridge from plastic .550 width that sits in the chamber similar to the red one from Benelli.  When I use this for dry firing the hammer strikes and moves the firing pin, but the hammer only moves about 1/8 or an inch and strikes with little force.  You can see the firing pin move on the bolt face and the hammer spring plunger moves about 3/32nd of an inch on the bottom of the trigger assembly.  

I also lathed a chamber plug out of nylon copying the chamber plug a friend had from the factory with his Benelli .32.  This plug holds the bolt back back slightly more than the red bridge.  The hammer is now striking the underside of the bolt that re cocks the pistol after shooting.  The hammer spring plunger does not move at all, and there are no firing pin marks on the chamber plug.  With both the red bridge and the chamber plug the hammer makes only the slightest click when it falls and the trigger feels normal.  

Does anyone know where the hammer is supposed to strike when dry firing with either the red bridge or the chamber plug.  



Thank you for your reply.  

David

Interesting. Dry wall screw? or Piece of leather. At the end of the day Benelli pins can break so have a couple extra. 

The hammer is internal and strikes somewhere under the bolt if I recall.

I don't think it matters but it would seem that less hammer travel and therefore less force on firing parts would be preferred. 

I frequently, but not always, use a chunk of leather behind the firing pin in a 1911.

David, that is the same behavior as the factory plugs in a pistol that has the disconnector. My 95 Atlanta did not have the disconnector but when I switched to an MP90 trigger, it now does what you see.

Does anyone have the empty chamber dry fire plug for .22 Benelli mp 59 e?  Does it hold back the bolt to the same place as the .32 plug?

I made my own dry fire plugs for both .22 and .32 Benelli pistols. See attached picture. Top one is for .22. Bottom is for .32. Made from plastic air lines as used in industrial applications.




Measurements for homemade .22 plug.
Inner tube, 5mm x 27mm
Outer tube, 8mm x 15.25mm




Measurements for homemade .32 plug.
Inner tube, 8mm x 30mm
Outer tube, 10mm x 15.25mm




Thousands of dry fires with these home made plugs and no problems.


I learned the hard way about dry firing a Benelli. Cost me two .32 firing pins and one .22 firing pin before I figured out, do not dry fire a Benelli.

This is the dry fire plug that I made for my .32.  Will compare to your dimensions, thank you, and make another for .22.
This one is lathed from nylon rod.  I threaded a hole and inserted a copper machine screw that was surrounded by vinyl.  

Thanks for your reply.

Any reason why you choose the overall length of the .22 to be 27mm where the .32 is 30mm.

The length of the outer tube determines where the hammer will impact the bottom of the slide.  With my plug the click when the hammer hits the slide is a very soft noise.

The distance from the face of the barrel to the bolt on my .22 Benelli MP90S is approximately .555 inch with the supplied chamber plug. The length of the portion of the plug that holds the bolt back is approximately .590 inch because it fits into the recess in the bolt cut for the rim of the cartridge.

Nope, it just worked out that way. The important part is the 15.25mm. That happens to be the exact measurement of the factory .32 Benelli plug I have.

15.25mm = 0.600 inch. So yea, we are right in the ball park at 0.010 inch difference.
