Beretta 92 fail to eject

I recently replaced the barrel on my Beretta 92FS and while at it, I threw a Beretta muzzle brake on because the new barrel is threaded.
I also put the longer stiffer spring on the rod.
At the range today, I was having a fail to eject every 3 to 4 rounds.
My guess is either it’s losing too much gas with the brake or I need a different spring?
In preparation from my next trip to the range, I already removed the muzzle break to see if it makes a difference.

Thoughts?
 
I have a 92FS myself, but no break on it. But hey, they worked for Jean Reno in Leon: the Professional so we know they gotta work. If the weight is adding weight to the end of the barrel, perhaps you need to increase the power of your load a bit or use a lighter recoil spring? Those are the first two things I'd dicker with. If you not loading up to Maximum already, inch up a little higher and see if that solves the problem.

That's what I'd do. It's not really scientific, but when we built the Nash Bridges gun down in Mexico, we found we had to increase the load to Maximum to get the thing to work (built on a Commander) because of the weight of the comp. I realize the Beretta isn't the same type of action, but it still might be the problem.

A lighter recoil spring is another idea -- but parts are hard to get here in Commieda, so if you reload, loaderup a bit.

And if you're going to watch Leon: the Professional either for the first time or again, make sure to watch the cut with like 30 - 40 minutes added in, it's worth it.

My thought is that you fundamentally don't understand how short recoil system works. 🤷‍♂️ Gas pressure has ZERO effect on the functioning of a short recoil handgun.

Short recoil operates on a balance between the recoil forces generated by the bullet and the weight of the slide-barrel and the rate of the recoil spring. Newton's Third Law of Motion.

The means by which a Beretta 92 barrel locks and unlocks means it is much more tolerant of additional weight being added to the barrel than the Browning type of tilting barrel lock. Unless the "brake?" is absolutely massive and made of depleted uranium, it shouldn't have any effect on the pistol cycling.

On the other hand, a much stiffer recoil spring would absolutely have an effect on the cycling.

My suggestion: Take the silly "brake" off and put the OEM recoil spring back in it.
 
Perhaps. We worked quite a bit with suppressors in Mexico because they are legal to own and use and are not restricted to purchase. Although I've been told that the Beretta was initially adopted because it "worked well with suppressors" that was not the case as we discovered it. Just like any Glock or 1911 we "played with" suppressed, a recoil booster was need to get practical reliability.

I'm sure that the average suppressor we were using was probably heavier than his muzzle break. We found that we could load the snot out of bullets to get the Beretta to work without the recoil booster, but then we usually got the crack of the bullet going supersonic. I'd still say he should try increasing the power of his load to see if that does anything and if it still jams, perhaps lower the weight of his recoil spring -- not necessarily by a lot -- to see what that does.

The Beretta works a lot better normally with light loads than the Browning/Colt/Glock drop down barrel guns which we found when we were initially adapting the .380 case to work with 9mm guns. We eventually found that the .380 case can take any power of 9mm load that the original 9mm casings can take when used in a locked breech but we didn't know that starting out.

I could always be wrong, but I think that just making a snappier load will fix his problem. No harm in trying as long as one doesn't go overboard. I'd be surprised if a heavier recoil spring worked to cure his problem -- but again, I can always be wrong. Up here, it's all about fun anyway and if he can get his 92fs to work with the break, more power to him. We were working with suppressors because it was fun, and we might actually have to use them. So we really wanted them to work reliably but we could never get the Beretta to be 100% without a recoil booster in the line-up.

my sig 320 does not cycle reliably with a linear comp... I don't know what the point of the threaded bbl was(compact slide with threaded bbl).... cause if it chokes while using a linear comp.... what would even have a chance at working??? liked the blast reduction but not much point if it doesn't cycle.
 
the compensator & heavier spring work against each other, either lose the comp or try again with the factory spring.
I had to go to a lighter recoil spring in my Glock when I tried a comp..ended up forgetting about the comp & went back to factory configuration
 
I ran a 92fs with a comp in 3 gun for several years. Spring weight was always the key factor for me. A fresh, stock weight recoil spring would be good for about 3k rounds. Then replace. + or - even 1lbs on the spring and it would have issues.

He installed a stiffer spring. He should just go back to the OEM spring.

OMG, yeah, you're right! I missed that. Old age and reading-comprehension obviously are moving against me. Yes, you're absolutely right. I agree that going back to the OEM spring should be his first test. Good call, Doctor Care About Me. I completely missed the "longer stiffer spring".

Duh!
