Beretta M93R Firing Pin Problems...

Post by Duncanature

I'm new to Model Guns. I just bought a Beretta M93R... and I can't seem to figure out how to load the damn caps... because the instructions are in Japanese. What usually happens is I load the cap in and when I pull back and release the slide, the cap ignites before I even pull the trigger. I really don't know what the hell I'm doing. Can someone help me out?

Edit: Topic posted under "Modelgun Caps, Cartridges & Magazines" first,
Ref: https://mp40modelguns.forumotion.net/modelgun-caps-cartridges-and-magazines-f6/beretta-m93r-firing-problems-am-i-loading-carts-correctly-t393.htm
but as the problem developed into Firing Pin breakage remainder of post moved to here.

Is this a brand new gun or 2nd hand and the first thing to check is that the detonator pin in the barrel is positioned right it sounds as if its too far forward and so detonating the cap. take the slide off remove the grub screw that is in the barrel and holds the pin in place then push the pin (you will need something to help you do this like a metal bar) fully home if you cannot push it further in then it is seated right (give it a good push) then replace the grub screw.
If that does not work let us know and also which model of 93 this is there a 3 versions, an abs a HW and the new proto, if this is a second hand one there are possible reasons you get this problem.

I believe I have the HW version. I have absolutely no idea what I'm doing. I don't know what a grub screw is...

Ok, take out your barrel and look on its bottom for a small set screw ( the allen wrench for this small screw is in the bag of extra pieces) Now, carefully loosen this screw and then, look in the chamber and push against the pointed steel "detonator" inside. If it moves backwards at all then that was your problem. If it won't move at all its one of two things, the screw is still touching the detonator and it needs to be unscrewed even more or, the cartridges are loaded wrong.
When you tighten the screw, PLEASE DO IT CAREFULLY! OR IT WILL STRIP OUT OR BREAK THE BARREL.

Here is a quick picture of the allen wrench in the set screws (grub screw) hole on the bottom of the barrel.

This will loosen up the "detonator" for adjustment. Did you need pictures of the guns disassembly?

Post by Duncanature

This is what i unscrewed... what do I do now? The screw didn't seem to release anything.

It should not really release anything that you can see immediately. It mearely loosens the "detonator" in the barrel. Now that you have loosened the setscrew, turn the barrel so that you can see the chamber area. Inside, you will see a shinny, pointed silver "rod" that is the detonator. Try pushing the "detonator" into the barrel further. If it moves easily then there might be a problem. The detonators fit quite tightly in the chamber with or with out the setscrew (also called grub screw) If you have an un-loaded cartridge that can be used to push in the detonator with finger pressure only.

Doesn't budge.

Ok, Then, it must have been the cartridges (loose "primers" or something) The Detonators are set-up from the factory quite closely and they seem to be dead-on when I check them. Try your gun now with the properly loaded cartridges and let me know how it goes...

Still doesn't work. I must be doing something wrong.

Can you tell me what its doing? I might be able to determine what is going on.

I load the cartridge in the clip. I chamber a round. I pull the trigger. Nothing happens.

Ah, did you by any chance try to "dry fire" your M93R? before or after you fired it the first time?

Duncanature wrote:

Yes... quite a few times, actually.

Oh, that actually might be the problem as I broke my firing pin (in the slide its plastic) and I had to make one out of stainless steel..I was going to warn you about dry firing your M93...Did you ever see any small pieces of round black plastic fall out of the gun?

Not that I noticed...
So is that most definitely the problem? Could it be anything else?

Ok, open the slide and look into the firing pin hole. Is the tip of the firing pin visible? Is the tip round?

Post by Duncanature

It just looks like a hole.

Post by Mark

Ok, now that the slide is open, push in the firing pin from the hammer side as far in as you can does the tip protrude from the slide? If so, is the tip round?

I don't see anything.

Post by Mark

Ok, one last check....using a flashlight (torch for those of you in the UK ) look in the hole. Anything?

That's what I was doing. When I push the thing in all the way I can see something in the hole, but it looks flat as near as I can tell.

Post by Mark

That's what I was afraid of..It sounds like you have broken your firing pin. They are not meant to be replaced as per Japanese law. The repair entails the breach block unit to be removed from the slide as it is super glued into the slide to prevent it from being easily replaced with a hardened real firing pin. And a new steel firing pin part to be made to fit. the original firing pin is actually a two piece unit with the front half being made of ABS plastic. The rear part is made out of steel as far as I can tell..

Could I have this repair done at a gun store? (I live in America).

Post by Mark



While I seriously doubt it, they might just try. However, the slide is made out of plastic (as is the breach block) if it is tweeked too far while removing it well...Now, if you have modeling skills and you can remove the breach block to get the firing pins one way retention pin out, then you can get the specs from me and have the local gunsmith make a new one for you.

Man, I really thought model guns would be easier to deal with than blank guns. Guess I was mistaken. I'll take it to the gun store and see what they say and then I'll get back to you.

Thanks a million for all your help and patience.

Post by Mark

Hey no problem! That's why I made this forum and my modelgun site: to inform people about modelguns! One of the main things that I tell people about modelguns..They are not simple and they can be a real pain..

Be sure to prepare your self for the gun store mentality before you go there with your KSC M93R as many of them will say that it is illegal or question why you would want a toy instead of a real gun....

The firing pin did this to me too and i accidently fired it dry only once and hey presto out fell the pin. My only solution was to buy a new slide which worked out a whole lot cheaper than a new gun. The new proto 93 is supposed to of addressed this problem and cured it
