Evo-USMC-23 Posted May 21 Posted May 21 Hello all, I recently purchased a stoeger coach gun used that’s had some work done to it in the past. Shot it for the first time yesterday, fired once, trigger did not reset. Had difficulty opening, closed and was able to fire the second shot. The trigger is now seized and has no play. I tried to do a manual reset, only the left hammer would reset. Any recommendations would be helpful. thank you
Larsen E. Pettifogger, SASS #32933 Posted May 21 Posted May 21 Well the above posts weren't terribly useful so I will offer a few comments that might be a tiny bit useful. The Stoeger single trigger is a Rube Goldberg device. Hopefully you are old enough to know what that means. If not look it up on Google. The right hand hammer has a hump on top that hits tab A when if falls and that pushes on tab B, etc. The good news is there are not that many parts in there. Take off the stock and open and close the action watch the trigger and hammers move as they are fully exposed when the stock is off. IF you have some mechanical ingenuity you should be able to see what is going on. If not you will have to take it to someone that has some experience with Stoeger single triggers. Which, unfortunately there are not an awful lot of.
PaleWolf Brunelle, #2495L Posted May 21 Posted May 21 Ask around at the Renton club to see if there is anyone in the area that may be able to assist.
Edward R S Canby, SASS#59971 Posted May 21 Posted May 21 It may be something simple you can easily fix yourself. The firing pin retention nuts tend to back out on my Stoegers causing malfunctions. I had a barrel stop firing on one when a fragment of lead shot got in the action. Take the shotgun apart, clean it, tighten fasteners and remove any foreign material and see if it starts working.
Dred Bob Posted May 22 Posted May 22 mine stopped cocking one side as a result of wear on the forend hinge/cocking plate (not sure what it is called). There's a thread here somewhere that I started not long ago. Replaced the forend metal piece and working great. I was able to manually cock the hammer so if you can't manually reset it then might not be related.
Evo-USMC-23 Posted May 22 Author Posted May 22 Thank you all for the helpful tips. Hopefully they will get me going in the right direction. I can tinker with it over the weekend and hopefully get it functioning.

Roger Rapid Posted May 23 Posted May 23 The Stoeger s/s,single-trigger action uses a long pin (A) that is held into a recess in the right hammer (C) at a point inside the action at (D). The rear end of pin (A) goes into a block (B) that is spring-loaded [see spring under block (B)]. When the hammers are cocked (this view is of the hammers released) pin (A) is pushed back by the cocked right hammer which pushes block (B) to be set in its rear position (not shown). In this position, when the trigger is pulled it lifts the right barrel’s sear allowing the right hammer to drop. However block (B) is what lifts the left barrel's sear and it can only do that when block (B) is in the forward position (that is, after the right hammer is dropped). So, simply stated, the trigger first releases the right sear and when the right hammer drops block (B) hinges forward allowing the next pull to release the left sear. To your question, the pin is held into the hammer by a very light spring under block (B) and the pin can come free of the hammer. Of course a lot of other things could happen that would jam your action - so at the very least this is what a proper single-trigger action should look like… RR
Roger Rapid Posted May 23 Posted May 23 One more thing... regarding the "some work done to it" ... Some folks will alter the cocking levers by removing material from the top of the levers with the goal of having the action open wider. This is the wrong way to accomplish that on a Stoeger. Removing material from the top of the cocking levers causes the levers to delay whem the hammers are pushed back, which means that the firing pins are still protruding into the fired primers are you try to open the action, and that makes it much harder to open the barrels.

RR This may not be a simple answer but I’ll ask anyway. I bought one of the Black Friday synthetic stock Stoeger’s and I would like to get it to open a little wider but not sure what to do? Thanks Randy
Roger Rapid Posted May 23 Posted May 23 RSE... To get the action to open wider on a Stoeger s/s single- or double-trigger shotgun file down the two bosses that are on either side of the extractor lever. (See file marks in pix below). File down until the file begins to touch the extractor lever - no further. RR
El Sobrante Kid Posted May 23 Posted May 23 Hi Roger Rapid, Thank you for your descriptions, and the pic. I think you are talking about the two surfaces with the arrows. Do you keep the factory angle (which I assume is parallel to the water table), or do you modify that angle when filing? Thx!
Roger Rapid Posted May 23 Posted May 23 El Sobrante Kid... Since the barrels are swinging open in an arc I do try to modify the angle slightly by taking more off the left of the bosses - as you view them in this photo. Very little needs to be removed since it doesn't take much to alter the opening angle of the barrels. Again, just go to where you begin to file on the ejector's opening lever. This adjustment should open the action about 4°-5° further. RR
