Depends. If it matters the k frame snubs aren’t all that concealable like j frames. I’d be inclined to take the trade myself. 60s are everywhere 19 snubbies that are pre-mim and pre-lock aren’t.
Assuming the 19 is in good shape I'd definitely do the trade. If nothing else you're getting a revolver that'll take .38 or .357 ammo. I'd say a 19 is definitely the more desirable gun.
