I recently purchased a Sig Pro 2022 with tac light for $250. The previous owner had trouble with removing the light from the rail so he took a grinder to the rail. Really messed it up. I was wondering if a gunsmith would be able to smooth it out and replace it with a metal one? If not any other ideas would be appreciated.

Depending on how trashed it is, and if you actually want to use a rail, you may be able to blend the polymer back into some tolerable shape.
If it's bad, you'll probably loase the ability to use the rail.

As for having a gunsmith "fit" a steel rail - Its going to cost you a decent chunk and it'll never be as good as the original rail.
Better to contact Sig and see if they'll do something like Glock does and just sell you a new frame with the same SN for a nominal fee.

The rail is still usable but the light is a little loose on it. Should I even consider getting it fixed?

This is one of those "How loose"? things.

It's at least possible one of the custom shops that has plastic welding technology could build the rail back up and restore it to shape.
Glues won't work since most won't adhere to the plastics used in guns, and it wouldn't be strong enough if it did.

It's probably possible the rail could be totally removed and a plastic or metal rail attached in it's place with screws.

It's at least possible Sig may have a repair method or could replace the frame.
I'd think that given the comparative ease at which plastic guns can be damaged, that Sig would have some process or technology for dealing with with this.
I'd probably talk to them first.

Given the cost of custom shop work, you might be better off to sell the gun and buy new, or just learn to live with it.
It's even possible to look at modifying the LIGHT to tighten the fit.

I would probably try and fix it with JB weld... maybe drill some holes for the JB weld to adhere to...
