Frequently Asked Questions
What is the difference between the Standard and Open Division 2011 brass base pad?
This Standard Division base pad fits within IPSC box dimensions. The Open Division base pad is longer, adds more capacity, and is designed for divisions without box restrictions.
Will this brass base pad fit STI & BUL magazines?
Yes — it fits all STI 2011 & BUL double-stack magazine tubes in 9mm and .38 Super and clone models.
Which finish should I choose for my 2011 brass base pad?
All finishes deliver identical performance. Black mirror polish is most popular for durability. Chrome and gold plating provide high visibility for easier magazine identification during stage setup.
Should I choose brass or aluminium base pads for my 2011?
Brass base pads (63g) are significantly heavier than aluminium (15g), providing faster gravity-assisted magazine drops and improved recoil characteristics. Choose brass if you want the weight advantage, or aluminium if you prioritise a lightweight setup.
Will this fit SVI or MBX 2011 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.
