I was wondering if someone can chime in .... Is it possible to reconstruct the breachface of a deactivated pistol that had a weld put in and had it cut at a 45 degree angle? I bought a pistol that I want to reactivate (and register) and I want to keep the numbers matching slide as its a collector. I know this is probably not recommended but is it possible? Its a small .380 caliber blowback gun and not a locked breach.
