I cannot agree with that statement. I think that there are too many firearms out there, even new models, that cannot handle +p ammo of any type. I also believe that bullet velocity and bullet selection must be mutually evaluated because some bullets do not perform well at higher than standard cartridge velocities, while others only perform at or near maximum.

As previously mentioned, hot loads are not synonymous with +p loads. A hot load is a load that is at or near the maximum limits of both the cartridge and the firearm it is loaded in. A +P load can be an overload in some firearms.

Most semi-automatic pistols are designed with a recoil spring(s) with a tension set to a certain recoil level based on a standard load range (somewhere between a squib load and a hot load). Since the reloading mechanism operation is based on the dynamics of spring tension vs blowback force, using ammunition that is not calibrated to the spring tension will likely cause the firearm to malfunction, and could result in catastrophic failure leading to injury or death. Spring tension can be adjusted by using heavier springs, such as was the case with the Canadian made Brigadier; a Colt 45 knockoff with heavier recoil springs capable of firing a 230 grain bullet at 1,100 to 1,200 fps ( much like the LAR Grizzly in 45 win mag) without risk of damage or injury.

I would advise against using +P or hot loaded ammunition in any firearm unless you are sure the design and condition of the gun warrant it's use.
