Hot reloads and self defense
It is well known by many gun writters, that a lawyer will " eat your lunch " if you use handloads for self defense. So I'd be very careful. The 9mm + P loads are all factory generated on equipment that none of us have. They have many resources from engineering to testing to produce their hot loads. If you want to blow up a $500 poly gun drop in some suped up handloads. I've been at a competition or ten where that happened. Sometimes the result of a progressive loader, sometimes not. Either way, the results were the same. Ambulance arrived! Plus P loads are only safe in guns that are rated for them, and for semi auto pistols, I can't recall any manufacturer saying their firearm was rated for them. Maybe some are, I haven't seen one. However, it is generally known that Ruger steel guns are very robust and Barretta has one model that some say can handle +P. Would you take the word of a stranger about a used car? Folks there is a reason why reloading manuals don't list plus P loads for semi's. My CCW guns have factory ammo in them like the previous writer stated, use what LE uses and your safe.
