I found this very helpful. I have just finished cleaning the firing pins on my 725 Sporting.
The lower pin was quite dirty but the upper pin had hardly any dirt on it.

This thread made the job very easy, thanks for sharing this information.

I realize this post is 7 years old, but this is really fantastic info. I've got an older Citori that I bought used, and it's generally in great shape, but every 500 shells or so the trigger would get stuck after the first shot. I assumed the internals were gunked up somehow, and while I didn't want to take it to a gunsmith for what was probably a trivial problem, I didn't want to start dismantling the thing without clear instructions on how to do it. This was just what I needed to know.

I just bought a used browning citori that was functioning fine. However after dry firing it, I can't get the gun to function anymore.

I've been searching blogs about the potential problem and ended up here . I think it is related to the hammers within the receiver. Or the receiver itself not re-setting.

Please if anyone knows about the Browning Citori trigger mechanism, contact me. I've spent at least 5 hours trying to research this problem and I feel that due to my lack of experience w/ o/u shotguns I may be missing something easy.

Describe your problem in more detail. Are you fully opening the gun after dry firing? If so, is the safety off and you pull the trigger, can you hear a click? After bumping the butt of the gun on the floor to reset the trigger, can you pull the trigger and again hear a click?

Old thread but great info. Just replaced pins in my 725 with JB pins. Thanks for the good instructions Mr. Wood, it made it easy.

Mr. Wood, thank you for an excellent post with pictures. I was able to take the stock off the gun and clean the firing pins for the first time. The hardest part was getting the long stock bolt loose. The gun is a 1994 and had never had pins cleaned.

Used this information to clean the pins on my Citori 20 gauge.
Would not have tried it without this.
They were in need of a good cleaning.

Thanks :D

Does anyone know if it is a design flaw in the Citoris that causes the lower firing pin to become extremely dirty compared to the upper firing pin? I'm wondering if any other O/Us have the same problem. I have my heart set on a 16 gauge Citori O/U.

The lower pin strikes at an angle, which can cause primer piercing in some brands. The piercing allows hot gasses to blow back and enter the firing pin channel, which can gum up the works. This piercing can also erode the firing pin tip, which adds to problems. If there is no piercing the channels should be about the same as far as residue build up needing to be cleaned over time.

Great instructions THANK YOU, I have found some brand shells will lightly dent primer in bottom barrel but alway refire in top barrel, even after cleaning? Winchester Universal 2/3/4" 1200 11/8" 7.5 and Federal Dove loads(white box walmart)? maybe 1 shell out of ever 50 shot? Primer strike present looks good but FTF, remove install in top barrel bang.
Thanks again for your time and effort to help all, Its Greatly appreciated!

Your diagnosis is 100% correct. I have a 8 month old 725 with this exact trouble, you would think a 15 year old problem Browning could fix. I called and ask Browning directly and they say they know it happens and can be prevented if you dont use "HARD" primers or shells with hard primers
The reason the bottom fire pin appears so dirty is because the pin has in the past broke through the primer, and now its getting blow back from primer ignition. The bottom pins comes into the primer at a angle down and to the right, between the angle and the hard primer material it rips the primer and exhaust gases blow back into fire pin chamber.
I was getting 3 /4 burn through primers per 100 shots, and had replaced 3 etched fire pins in 3000 rounds. talked to Browning multiple times about this problem, they did give me specs for pin but best fix is to avoid shells with "HARD" primers.

Best solved by using hulls with a malleable strike surface such as those on American made shells. Most Euro hulls have a steel strike surface that cracks easily causing the issue.

THANK ... YOU ... AGAIN , Mr. Wood !!!!!!!!!

Just knocked this job out in record time and only because of this extraordinary service by you to the members here at SGW.com (and beyond). Only doing this once every 2 or 3 years it is a blessing to be able to quickly peruse your pictorial and not make any goober mistakes!
