SierraPapa now produces a Complete Extended Magazine (includes a modified Beretta 8045 mag) and a Magazine Extension Kit (you supply your own mag, which we can modify for you) to increase the capacity of 8045 (Cougar) series CX4 magazines to 15 or 16 rounds, as appropriate for your local restrictions.
This magazine extension is a high-quality product designed to supply absolute reliability. It requires the use of a modified original Beretta 8045 magazine and the original cartridge platform. The kit consists of 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.
