What is 38 plus p caliber?

Answer 1

.38+p is a type of .38 ammunition. The "+p" designates it as a hot load - one that will travel at a higher velocity and potentially dump more energy into a target than a standard load - and these more potent loads should only be used in firearms that are rated for such ammunition. If you use this in a gun that is not capable of handling the power a catastrophic failure could occur; this includes, but is not limited to, barrel damage, hammer/firing pin damage, and even the gun basically blowing up in your hand.
