Actually I would suggest a .357 revolver. You will pay a bit more for one over a .38 special but it will be more sturdy (since it has to handle the more powerful round) and of course gives you the option of moving up to .357 if you think you should need it. .357 revolvers will handle .38 special rounds as well just fine.
Taurus usually makes a good enough revolver, but do make sure of the particular one since their quality control is known to be spotty. It could just be safer to go for a Ruger though it will likely be a bit more expensive (a Smith and Wesson would be the nicest option, but much more expensive). I’d suggest a 3 or 4 inch barrel (since it is not for carry).
Sounds like a gun safety class might not be a bad idea since you express some concern on the subject.
TY. Yes, I would take a class.
