Beretta M9A1 - Is This Normal…?

[mrvash]

Hey guys,

With my Beretta M9A1, today I had noticed that I can manually cock the hammer, pull the trigger and the hammer drops with the safety on. Albeit, the firing pin is rotated out of the way of the hammer when the safety is on, so I don’t think that you can fire it this way. But is this normal? I’ve fired around 400-500 flawless rounds through it and I had never noticed this until today.

Note: When the hammer is dropped and the safety on, the safety works as normal, it deactivates the firing mechanism, hammer, etc..

Please see the video for reference. (Gun had been safety inspected and cleared of any ammunition; ammo is stored, and locked, in a separate area of the home. Firearm was also pointed in a safe direction):

Not normal, with the safety on the hammer should not be able to remain cocked

The safety has a long pin that will contact the trigger bar.
On my models this pin forces the trigger bar down.
When the safety is ON, can you pull trigger and hammer starts to move?
if yes than the pin on right side of safety is short or missing.
Remove the slide and you can see the small pin move down inside the slot when safety is on.



Edit..The hammer release lever is held down when safety is on.
You can see the cut go from flush when OFF, half round when ON.
Think this is your problem.

Nope....not normal.

Holding my 100% stock, unmodified M9A1 in my hand right now and the hammer will NOT lock back with the safety / hammer drop engaged.

[Mr. Beretta]

Foothillman is correct. (nice pic BTW).

When the safety / hammer drop is engaged, the pin is down.

When it is not engaged, the pin is up, allowing the hammer to be locked back.

The safety has a long pin that will contact the trigger bar.
On my models this pin forces the trigger bar down so hammer will not "lock" when manually cocked.
When the safety is ON, can you pull trigger and hammer starts to move?
if yes than the pin on right side of safety is short or missing.
Remove the slide and you can see the small pin move down inside the slot when safety is on.



Edit..

Yep, mine seems to have all those parts intact still. One thing I just noticed is that when the safety is on and I cock the hammer, if I push down ever-so slightly on the safety it'll decock the hammer.

Then inspect the top of your hammer release lever (yellow circle in pic). Be sure it does not look flattened or worn. Also look at the safety lever barrel in the slide (green circle) which would contact this lever and see if you notice any unusual wear.

It may be that your slide needs a good detail cleaning, or a detent has gotten into a weird way that prevents the lever from going to full safe and staying there.

The difference between the short pin (that would have come with the g-conversion kit) and the factory fs pin is 0.050 of an inch. So both would be visible, and would explain why it works when pushing down on the safety, but just not quite when cycling the slide.

I see! I purchased the gun used so I am unsure if it was ever converted or not..

Note: When the hammer is dropped and the safety on, the safety works as normal, it doesn't engage the hammer at all.

op - you purchased this gun used so;

is this first time handling it or has it worked normally and this malfunction occurred suddenly?

do you have the sellers contact info? have you tried contacting them to see if they modified it?

personally, I would send it to a qualified gunsmith minimum, Bolsa Gunsmithing is west coast authorized Beretta service..

there may be parts replaced that look identical to the original with only slight dimensional differences..

or bubba'd parts difficult to identify - someone could have been attempting FA, trigger manners, or whatever and decided to cut bait..

might even be a factory defective gun and previous owner never figured out what to do with it..

but either way - the malfunction you're describing may result in unwanted discharge and should be professionally repaired..

good luck!

and btw, glad I saw this, found my m9a1 tlr batteries were low
