Brass vs Aluminium — Which Should You Choose?
Aluminium base pads suit shooters who want an extended grip surface without adding significant weight. If you prefer heavier magazines for faster drops and improved recoil characteristics, consider the 2011 Brass Standard Base Pad (63g) instead.

Frequently Asked Questions
What is the difference between the Standard and Open Division 2011 base pad?
This Standard Division base pad fits within the IPSC box dimensions at 15g. The Open Division base pad is longer, adds capacity, and is designed for divisions without box restrictions.
Will these fit the 2011 STI & BUL magazines?
Yes — it fits all STI & BUL 2011 double-stack magazine tubes in 9mm and .38 Super, including clones.
Can I use different colours on my magazines for identification?
Absolutely. Many competitors use different colours for magazine identification — for example, distinguishing between 9mm and .38 Super loads, or marking primary magazines versus backups. Six anodised colours are available.
Should I choose aluminium or brass base pads for my 2011?
Aluminium base pads (15g) suit shooters who want an extended grip surface without adding significant weight. Brass base pads (63g) are better if you prefer heavier magazines for faster gravity-assisted drops and improved recoil characteristics.
Will this fit SVI or MBX magazine tubes?
No. This base pad is designed for STI and Bul Armory double-stack magazine tubes only. SVI and MBX magazines use different base pad dimensions.
