About a year ago my grandmother's house flooded and she decided to give my deceased grandfather's guns to her children and then to my brothers and myself. The pistol I got is a Charco .38 SPL Off Duty. I know this generation is regarded as lesser in quality, however, I want to keep it as a back up to my XDM. I can't find much information about running +P loads in it so I've come to ask people with revolver experience-of which I have little of. I only intend to keep this gun as a back up temporarily.
