45ACP+P ammo is externally/dimensionally identical to 45 ACP ammo and can be fired in any 45 acp firearm that is in normal operating condition. However, the greater pressures and power of the +P ammo will give you greater slide velocity and if you are going to shoot more than a box or two of +P ammo, you should consider replacing your recoil spring with a Wolf Spring that gives roughly 4 to 6 lbs more spring weight than factory stock springs. A shock buffer might also be a good addition although it is not too necessary if you use the stronger spring.

As always, with Buffalo Bore Ammunition, we use real world firearms to give real world data and results. Laboratory test barrels tell you little about what kind of speed you can expect from your stock firearm.
All our 45 ACP+P loads utilize flash suppressed powders so that you will not be blinded by your own gunfire should you need to fire in the dark when the criminal element is at work.
The three JHP loads are design for defense against humans, while the two non-expanding loads are designed to shoot through large shoulder bones or the skull on a black bear. These non-expanding bullets also work well if you need to shoot through cover like car doors or stick frame walls.
