I have an 870 that is having some issues. My question is could I take the trigger assembely and bolt out of my 2 3/4" wingmaster and put it in my 3" wingmaster magnum to see if it clears up the issue? Are the trigger assembely's interchangable? Thanks Rich.
 
I would think they are interchangable. What problem are you having? Maybe some one here can point you in the right direction.
 
The spent shell is getting caught in the ejection port. This is an older wingmaster magnum I believe from the 50's. At first I thought I was short shucking the gun but now I'm thinking otherwise. I bought this gun as my go to waterfowl gun. I had it reblued, barrel cut down to 26",threaded for Carlson True chokes and bought new wood from another site member. I'm thinking some of the parts are getting worn.
 
The FCG's interchange within gauge and frame size. Is your receiver a Magnum, or did you just stick a 3" barrel on a 2.75" frame?
 
I have both a magnum reciever and a standard reciever. I would like to take the trigger group and bolt out of the standard wingmaster and put it in the Magnum. will they be compatible.
 
Yes, as long as they are both the same gauge and frame size.

I don't think you are on the right track though. What combination of parts are you having issues with?
 
I want to switch the bolts to see if it will eject the shell better. The extractor is part of the bolt. I have also had a problem with the gun double feeding. I think this might be worn a worn feed latch. These are punched to the inside of the reciever. My plan is to fix one problem at a time. First the full ejection of the shell. Thanks Rich.

As far as I can remember yes you can. Some of the real real early ones had a smaller ejection port but that should not effect the bolt operation but could catch a hull on ejection
What is the issue???
 
This is an early 3" wingmaster magnum. Sometimes the spent hull is getting caught 1/2 way out of the reciever. Maybe I need a new ejector spring inside the reciever. It apears to be O.K. but maybe it is worn from lots of use. I gave the gun a real good cleaning. When I took apart the Magazine tube I found a solid steel bar in the magazine. I don't know if this was to balance the gun or to soak up recoil by adding weight. I bet it is close to a pound. I thought it was a little heavy after a coulple laps around Pelee Island, pheasant hunting. Has anyone ever had the same issue of there gun not ejecting the shell completely. How did you remedy this? I've been using a super magnum express with no issues so I believe I am not short shucking the gun. The gun has done this since I bought it. I almost threw it overboard while hunting out of a layout boat this fall. We where covered in bluebills and I was only getting one or two shots offf. Then while pheasant hunting it was doing the same thing with 2 3/4" high brass shells. I don't know what would cause this issue.
 
The extractor spring is probably weak and needs replaced. I would clean that assembly and replace parts as that is both cheap and easy.
 
I will try this but it is extracting the shell from the chamber O.K. but it is not ejecting the spent hull all the way out of the reciever. I think it would be the ejector spring inside the reciever that is riveted to the inside of the reciever. This is not that easy of a fix. I will order a new extractor and spring to do some preventative maintenance.
 
This is the culprit. I believe it is about a 1950's model it had the sun glow stock on it, I replaced it with a stock and forend I got off the E.E. on this forum. I had the 30" barrel cut to 25" and Carlson's true choke installed and a reblue job done.

Ok lets start from scratch. 1950" you say. 3" mag came out in 1955 were very rare and I have never seen one with a VR barrel until the 60's.
So on your serial number does it end in V or M .I think you have a barrel off another gun also
If V it is not a 3" gun and you have to change the ejector set up inside the receiver to the shorter 3" one. Also the early ejection ports where shorter so you have to measure yours agaist a known 3" gun and may have to open it 1/8 to 1/4 to match what a 3" should be.
If the receiver is a M replace the ejector spring set up and be careful not so screw up the ends of the two rivets so you can reuse them.
If you take your time that is no problem and the entire job can be done in 25-30 minutes.
So what letter is on the end of the serial number

Cool. Then for me the next move would be changing the ejector and spring which you have on order. If you take your time you can resuse the original rivits. Let us know if that makes the difference.

I assume you already checked the existing one to see if it was slightly bent and could not be straightened on the end a little bit. It takes very little to make them screw up.

I have recut the ejectors before, saves replacing and riveting.. The spring needs to come off though during the process.
 
The front rivet is the one that might be reused. You can buy(Brownells) or make a cutter. The cutter is flat faced, is the diameter of the inside width of the ejector, and has a hole in the middle for the post on the rivet. The flange is cut off, the spring removed/replaced, then what is left of the rivet can be used to secure the spring.

The rivets do show on the outside of the receiver and will be obvious when altered. I recommend learning as much as you can about them before attempting alterations or replacement.
