Evening gang: (I've posted on this before but no amount of searching is turning up the thread)

Looking for some insights and perhaps a reference to a decent smith to take a look at this Citori. It's a Special Steel model chambered for 3 inch shells, the gun was bought new in the mid 90's and has been in our family ever since. What is happening is that on the second shot be it one the top or bottom barrel there is occasionally a distinct pause bordering on FTF (fail to fire) for a moment, the round does go off a second or so later almost like the hammer is dragging or hanging up and not falling cleanly.

I've taken the stock off and de-greased the action and re-lubed appropriately, this has improved things in that the condition doesn't occur as frequently as it was but is still happening once in a while maybe 2 rounds out of a 100 fired. I would like to solve this once and for all as the gun means a lot to me, it was my Dad's first O/U.

I found this info below and wonder if a deeper cleaning is needed or something more involved that would need a smith to handle such as the sear tolerance referenced in the quote below.

From another site referencing a gunsmiths manual for Citori's

When the gun fails to set up for the second shot, look for burrs in the trigger piston hole of the inertia block system. Also check for debris that has found a home between the top of the tang and the rear end of the trigger. Another cause for this malfunction is too close a tolerance between the sear tails and the connector. It should be 0.012 to 0.014 inch and could become less than that if the stock bolt is overly tightened during stock reinstallation.

Another solution a few have suggested is to replace the original inertia based trigger with a mechanical one from Briley or another manufacturer I can't recall the name of at the moment. No one has been able to give me a cost to get this done, wondering if any of you CGN'ers have an idea of what kind of ballpark this would be in money wise and whether it's the ultimate solution to eliminate this as a problem altogether.
 
Sounds to me like the gun has just stiffened up abit from not being used .buy a couple snap caps and dry fire it a couple hundred times while watching tv.then clean and relube the internals.
 
The inertial system cocks the second hammer on recoil, its either going to work or not and since your gun is cocking the second shot I doubt that's the problem.

I had a similar issue with my Citori, although I didn't have a delayed fire situation, my simply wouldn't fire the second shot. What I discovered was was a build up of grime and grit on the firing pins. Enough that every once in a while one or the other of the firing pins would hang up slightly. By the way this was after thousands of rounds fired, probably on the order of 6 or 7 thousand.

If you didn't actually remove the firing pins and clean them and the hole I would suggest doing that.
 
Thanks for the replies guys, the gun does get used a fair bit so it's not from lack of use...the one thing I haven't done is clean the firing pins. Wasn't sure how to do this but found a great post on Shotgun World that looks like it may be worth doing, going to give it a shot today just have to pick up a right sized drift punch.

Good article, wish I had that when I did mine, but it went pretty easily. Some advice, take pictures as you go and remember the alignment of the retaining cuts in the pins.

Good luck and please let us know if it fixes the problem.

Also, do a search for the Browning Parts Price List. It has a good exploded diagram of the gun which helped me greatly.
 
That's an easy fix. Your second firing pin is at an angle and is worn off so it doesn't hit the primer as hard or not hitting it at all sometimes. Order a pair of new strikers and replace them yourself. Will cost you $10-20 tops and 45 minutes of manual labour :)

I have the same issue now, did this end up working?
 
some Citori's firing pins especially the lower ones develop these issues. The pin ends get worn because of two things -- powder corrodes the ends and the lower pin is at a very step angle. The cure is fast and not expensive. Replace the worn pin.
 
Considering the delay happens on both barrels,. as described in the first post, you lads that suggest replacing the bottom firing pin may be a bit off base....
 
Quick to answerbut fail to read post and digest info . U are on the right track with the firing pin clean up also if there are springs in with the pins possibly replace them . Or simply order new pins and new springs and eliminate that issue completely . Firing protrusion should be 60-70 thousands of a inch . It only takes a little bit of residue to change those specs .
