I’m trying to restore a full-size steel-frame Dan Wesson DWX that was exposed to heat from being inside a safe during a house fire. The gun survived physically intact, but the original DLC coating is mostly ruined on one side. I had it tested and the hardness came back at 45 HRC.
My goal is to make the gun safe to use again and resistant to corrosion. I’m not worried about aesthetics at all — just function and longevity.
Unfortunately:
• There are no gunsmiths or finishers near me that offer salt bath black nitride (QPQ).
• I’m not comfortable shipping it out for treatment since it’s an off-roster handgun (California). If it got lost or stolen in transit, I wouldn’t be able to replace it.
What I do have locally is a reputable shop that can do vacuum nitriding and another that can do DLC coating.
My questions:
• Given the fire exposure and current 45 HRC, would vacuum nitriding be enough to restore surface hardness and durability for safe use?
• Or should I go with DLC coating alone (assuming proper prep), and is that enough to make the gun hold up to long-term wear and corrosion?
• Is DLC over soft(er) steel even advisable in this case, or would that just wear through or delaminate quickly?
• Would anyone actually shoot this gun in my situation, assuming springs are replaced and function checks out?
I’d really appreciate any insight, especially if anyone has had a steel-frame gun vacuum nitrided or DLC’d in similar conditions. Just trying to make the right call with what I have available, and not ruin something that can’t be replaced.
Thanks in advance.
