A while ago I picked up a steyr hahn pistol that I believe is chambered in 9 x 19mm and upon inspection I noticed that the chamber has some gouges in it just forward of the feed ramp and I was wondering if the barrel could be saved by tig welding the gouges then re-reaming the chamber or is it scrap.

How does it shoot?
pretty sure its 9 x 19mm, I'll need to do a chamber cast and see for sure.
Haven't shot it yet, its had other issues that I've been working on getting sorted out.
Those gouges would have to be pretty deep to cause any feed/ejection issues.
I don't believe any of those pistols were every chambered in 9x19 but that doesn't mean it won't chamber and fire the round.
I think mbogo is dead on with it being chambered for the 9mmSteyr round.
Still, it's possible someone had it customized and that's where the gouges are coming from

According to Wikipedia: “After Germany annexed Austria in 1938, the Wehrmacht ordered 60,000 M1912 pistols rechambered to 9mm Parabellum which remained in service until the end of World War II.”
Thanx for that. It's a new one for me.
I've never seen one but that most certainly doesn't mean they aren't out there.
Considering the firearm, those chambered in 9x19 would be relatively rare birds. Does Wiki say if the pistols were delivered?? Likely they were.
I decided to remeasure the chamber and I'm starting to think it is in 9x23 steyr, I looked up the CIP spec for the 9x23 steyr chamber and it's closer to that than 9x19. Also as was said before a number were chambered in 9x19 during WW2, I've also included a picture of the gouges in question, the worst one has a bit of a burr that might cause issues.
9mm para pistol will have a “08” stamp on the left side of the slide about in front of the ejection port and usually german proofmark. Otherwise it will be in 9x23mm Steyr. It will fire 9mm para but in the process you are causing throat erosion since the case is too short.
Edit: a good video to help you find what you have.

They don't show the Steyr Hahn configuration, only the newer model pistols.
OP, I have seen Steyr Hahn pistols with chambers cleaned up and sleeves silver soldered into place. They can work very well when the smith does it properly.
The 9x23 round used to be made by Winchester. I don't know if they're still making it. European ammo is also available.
If that were my pistol, I would leave it as is. What your pics show isn't anything to be worried about IMHO.
Actually I'd bet a round Timmies coffee that a 9 x 23 Steyr won't chamber or fire 9 x 19 Para; you would be forcing a 9.93 base into a 9.7 chamber. It'll start to chamber, then choke up about 2/3's of chambering completely.
The 'Old school' way of converting these involves machining out the chamber and pressing in a 'sub chamber' so speak.
They handle it OK, but the bbl & slide need to be fitted IMO.
After you do the chamber cast, Rusty Wood (and others I imagine) carries Starline 9mm. Steyr brass if that's the correct chambering you need.
For stripper clips I used to use the ones that came with packs of 7.62 X 25 Tokarev surplus ammunition. They fit and worked like they were made for the Steyr.

It's a hundred+ year old pistol.
I think you are looking too close, if you are thinking those marks are something that would get the barrel scrapped.
Knock the tops off any burrs that are sticking up enough to cause you feed or extraction issues, shoot it, and have fun!

Tokguy, I've seen it done differently but what you describe would work. I would think "shrink fit" rather than "press fit"
The method I described involved silver soldering a piece of barrel metal into the chamber and reaming a 9x19 chamber after. The two pistols I saw done this way worked well. However, I believe the recoil springs were changed out for heavier springs.
