DFW shotgun barrel threaded for chokes

[robert13t]

I bit the bullet and purchased a shockwave 12ga. I think it would make a great home defense and win a brace a brush deer or turkey gun. Problem is it’s. Or threaded for chokes. Anyone know of a gunsmith in DFW area that will thread a shotgun barrel for chokes? Class 3 and grumpyguns won’t do shotguns. TIA

It may be cheaper to just buy a different barrel.
