It has a 7075 aluminum frame paired with a polymer grip module, and its double-column magazine design gives it a 17+1 capacity.

## What Customers Say

*AI-generated insights from customer reviews*

The 2011-style double-stack format behind the OA-2311 tends to draw praise for a slim, ergonomic grip that still holds more rounds than a single-stack 1911, and owners moving from a standard 1911 usually adapt to the OA Defense controls quickly. The aluminum frame with a polymer grip module keeps the gun light for its size without giving up the crisp single-action trigger feel the platform is known for.

On the range, the optics-ready slide is a common draw since it saves a separate milling job, and the ambidextrous safety gets good marks from left-handed shooters. A few owners mention that magazine compatibility and spare-parts availability are worth checking before buying into a smaller-volume 2011 brand.

Opinions on value tend to hinge on the comparison point: against a major-brand 2011, the OA-2311 is seen as reasonably priced for what it includes, though buyers coming from a basic polymer striker-fired gun may find the price still a step up.
