semi-auto rail repair, possible?

I recently bought a Star "Modelo Super" in 9mm largo, unfortunately without inspecting it well.
After getting it home and getting ready to clean it I noticed a crack along the frame rail. I'm wondering, what are the chances I can get a smith to repair the cracks? Yeah, while taking pictures, I found more.

Thanks for reading/ looking!

In cases like this the first question a pistolsmith who's qualified to repair it will ask is....
"Say buddy, just how much money DO you have?"

I you have enough money anything is possible.
This type of repair will call for a Master pistolsmith/master welder. They're not all that common but they are around.
With a pistol of this quality, and not being a valuable historical gun, even most experts would probably ultimately turn the job down.

I would guess that the cracks would have to be machined or ground open so the welds would have enough room to fuse the steel.
Just welding over the cracks wouldn't work, they'd just crack again.
Note that silver brazing (silver soldering) will NOT be appropriate for this.

After welding the rails and frame area would have to be re-machined and fitted to the slide.
"Probably"?? the frame would need to be professionally re-heat treated to fully restore it to shooting condition.
The frame would require a refinish, and these days that's a $200 job most places.
See where this is going?

All this is well within the range of "Not at all worth the cost".
You'd be far, far better off stripping it and selling it for parts and using the proceeds to buy a better pistol.

Fair warning.... This is NOT a job for the local general gunsmith OR the local expert welder.
This type of work requires a real expert. While someone else may attempt a repair, I'd bet money that it would fail very quickly.

So, due to the very high cost of a real professional job you're best to either part it out or turn it into a wall hanger.
Even if you spent the money you'd still just have a cheap quality gun made worth even less because of the damage that can't be hidden.

Sorry, this is a matter of the hard truth.

DFW I truly have respected and appreciated you for quite a few years now. Maybe this one time you need to take another look. Upon looking at the my own Star, those "cracks" are merely separations where the ejector piece is mounted in the frame. If this is not loose and nothing is significantly rubbing any part of the slide or hammer, this should be good to go.

So mac, is anything loose or excessively rubbing?

Nope, it's tight, it's only loose/rattles when the slide is locked back. The only other things wrong with it is a broken spring guide and I need a 9mm luger barrel for it instead of the 9mm largo it came with (the OE barrel looks close to shot out). I want to try it with 919 but the extractor probably won't hold it well enough for it to fire.

Thanks for reading this, I hope my $200 won't completely go to waste.

Hummm, it pays to take more time to look.
The OP said it was cracked so I took it at that.

I stand corrected.

If the 9mmP barrel fits properly (or gets fitted), I'd try a shot and check the brass.
