FAQ

Why is this model called the MA-9 Classic?

The MA-9 Classic focuses on the core features of Moriarti’s compact 9MM platform in a straightforward black configuration. It provides the Micro ARP format, Glock-pattern magazine compatibility and slick-side Non-LRBHO upper without the custom finishes or specialty configurations found on other MA-9 models.

Product Image Notice

Images may not be the exact representation of the product. Handguard design, muzzle device, grip, receiver details and other non-material component appearances may vary based on production and availability. Please refer to the product description and specifications for the configuration included.

FFL Transfer

This firearm must be shipped to a licensed FFL dealer for transfer. Please have your receiving FFL email a signed copy of its license to [email protected] and reference your invoice number.

FAQ

Does it ship to an FFL?

Yes. This is a complete firearm, so it ships to your local FFL dealer for transfer. The buyer must meet all federal, state and local requirements.

What magazines does it use?

Glock-pattern 9mm magazines.

How does it operate?

It is a direct blowback system, so it has no gas tube. A heavy PCC buffer is used for reliable cycling.

Does it have last round bolt hold open?

No. It is a Non-LRBHO design, so the bolt does not lock back on an empty magazine.

What does "SBR ready" mean?

The rear setup accepts a stock, but adding a shoulder stock to a pistol with this barrel length changes its federal classification. Do it only in compliance with NFA and state rules.
