depends on tools to hand .braze or silver solder would work

i would be surprised if you could get it hot enough with butane to silver solder. it might MIG but would need lots of filing to fit. and that would remove most of the weld strength

if you are having trouble with retaining heat with butane, mix some plaster of paris and some sand. 1:1 ratio of plaster powder and sand and then add water to suit. when it hardens it is pretty much the same as fire brick and you can mould it to make a pot or bowl to hold the parts in easily.
if you can get hold of a few handfuls of sand it only cost a few quid for the plaster powder

Almost certainly the original weld was a resistance weld, I don't know if gun components are made from mild steel but I would TIG it, If you go down the brazing route find someone with an oxy acetylene set up to do it, either way its a two minute job.
Might be a good idea to get a piece of scrap the same size and make sure you can get it bright red quickly with the butane, it's a pain in the @rse having to start again with a bigger torch when you find the joint didn't hold as the flux went off before you could get it soldered
I don't know what type of steel is used, in common with a lot of American firearm parts I've come across it is fairly roughly finished but hard as hell.
I'm not convinced I'd get much of a plug weld on this given its size and the limitations of the MIG.
Is anyone local (I'm in East Devon) who could do this?

the equivalent part in my browning is case hardened mild steel, may be the same with yours? although mine is not a pump so not sure

run a file across it and u will soon see if it has been hardened

A genuine question - are pump actions legal in the UK?

if u can file it it is soft. if it just runs over the top and doesnt cut its hard .oxy acet and braze would be the quickest and easyest and a quck rub up

The americans like 4140, which is en19 this side of the atlantic, for firearms action parts, they also like 8620 which is a case hardening steel. I wouldn't be surprised though if smaller parts that aren't pressure bearing are made out of something similar to silver steel and through hardened. There are a few qualified gunsmiths on here, they should be able to help you.
One thing i do know from welding firearms bits over the years, if they are hard, when you weld them they will crack like billy-o.

Yes, they can be had on a section 2 (shotgun) certificate with a magazine capacity of 2 + one up the spout, just the same as semi-autos. If the magazine capacity is over 2 they go on section 1 (Firearm) as a high capacity shotgun.
This one is a section 2 though I do still have an unfilled slot for a section 1.
