Home Forums Hunting & Shooting Gunsmithing Which Solder ?

I am going to limit the sear engagement on a Pietta 1858 Remington New Army to get rid of the trigger creep .

I have never soldered and will be soldering a small ,thin piece of Mild steel below the full cock notch on the Hammer.

Which solder do I need to use to do this?

I already have some Bernzomatic Metal Work Solder
Silver Bearing Acid Core Solder,Lead Free with a 430 Degree F melt temperature., .062
Will this be ok to use ?

Like I said I have never done any soldering

I do have a Bernzomatic Basic torch that I bought at Walmart several years ago
I also have a Wood burning pen that also has a soldering tip provided with it,It burns at about a thousand degrees F
Should I use the Torch or the woodburning pen ?

I would also appreciate advice on soldering for this project ,

Thanks
