15/16-rd 45 ACP Magazine Extensions
SierraPapa offers two options in high-capacity 45 ACP magazines. The Complete Extended Magazine includes our extension body and a modified Beretta 8045 mag from our own stock, and the Magazine Extension Kit adds our extension body to the 8045 magazine you supply for modification in our shop. Either option provides you a high-quality magazine extension proven to supply absolute reliability.
The supplied parts (photograph at right) include a new black-anodized aluminum magazine extension body to extend the original steel mag, two new custom-designed springs and a plastic spring alignment spacer. The unit is designed to allow reversion to the original 8 round magazine if required. Both options require a very minor modification to your magwell insert. Please read more here about magazine modification (we do this) and magwell insert modification (you do this).
