One thing of note also is the High Force 44 solder Robert recommended is a lead free solder. now I realize we are not really concerned with the enviromental impact on a job like this, but it has a much higher tensile strength than ordinary tin/lead solder, thus is a particularly good candidate for this purpose. After getting it fixed you may want to take note if this gun has a bbl check mechanism or not. Many hammer guns did not & the older thay are the less likely they will have one. In such cases the bbls are stopped by the forend iron contacting the frame bottom. Hard opening can put tremendous stress upon the forend lug. Another reason I do not recommend "Carte Blanche" the carrying of hammerguns afield with the actions open.
Also note most solders have a slightly higher "Re-Melt" temp than the original melt temp. Another reason for following the method Robert recommended of heating "Just Enough" to flow the solder. Excellent advise all the way through Robert.
