45 ACP +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 lb 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. #html-body [data-pb-style="62DF82881DAA6"]{justify-content: flex-start; display: flex; flex-direction: column; background-position: left top; background-size: cover; background-repeat: no-repeat; background-attachment: scroll; border-style: none; border-width: 1px; border-radius: 0px; margin: 0px 0px 10px; padding: 10px;}#html-body [data-pb-style="62DF82881DAB3"]{border-style: none; border-width: 1px; border-radius: 0px; margin: 0px; padding: 0px;}
