shortening the barrel does make the gun look aLOT better though.

On further research it looks as though the barrel must be pinned THEN have the hole where the pin is placed soldered over so it cannot be removed. It sounds simple enough on the surface however I am sure the blueing would be discolored from the heat of soldering over the pin hole which means the whole barrel would probably have to be reblued. I guess it depends now on how much effort and cost I am willing to pay to have this done. Unfortunatly things are never as simple as it sounds like they would be. Oh Well. I'll have to think about wether the cost justifies the cosmetic appearance. Also I would be concerned that the blueing salts would eat away the required silver "Plug" I guess it's not as easy as I thought it would be.
Thanks for the input though

Soldering takes place at temperatures below 800F. The term brazing is used for temperatures above 800F. The old term “silver soldering” is incorrect- it is silver brazing, and so called in commercial circles.
This may seem an anal point, but ATF requires a brazing process using temperatures of 1100F or more for the attachment to be considered permanent.
If the pin option is used, most folks weld the head of the pin, not braze it. Silver brazing is used as a primary circumferential joint that only shows a slight ring of gold colored alloy when finished.
Bluing salts have no practical effect on the silver alloy.
For various reasons, this is the method I prefer when doing these conversions.
