Yes, there is nothing inherently illegal with that pistol or possessing it for personal protection. The comments should reflect that, if you are a felon not legally allowed to own a firearm and you use it in even a self-defense situation, you could be in trouble. Also, if this pistol is listed as stolen, even from many years ago, it may be an issue. Just pointing out things to consider with your question. Look at every detail from all angles.
Also, learn the laws around concealed carry and definitely, without a doubt, shoot it enough to become proficient with it. You need to remember that every bullet you shoot in any incident has a lawyer attached to it. Great advice!
