Oh yeah I didn't think about that. I just didn't want to separate the number completely from the frame. But that probably isn't a issue as in not defacing the number or replacing it. Plus it still matches the barrel and my paper work from when I registered it.

This will actually make it easier because I could work with the back strap and probably even roll it to match a round butt profile and have minimal grinding on the rear.

I think I'm definitely going to go this route and go ahead and do the conversion.

Is standard E70S-6 filler good enough to use for welding? Or do I need a exotic filler rod?
