Frequently Asked Questions

What ammunition performed best with the ECM R11 & Norsso Ported Fuse 365 build?

During accuracy testing at 25 yards, Speer Gold Dot 124gr hollow points yielded the best results, producing groups as tight as 3/4 of an inch. Winchester Ranger 147gr also performed well, with groups just over 1 inch.

How does the Norsso ported barrel affect recoil on the P365 build?

The Norsso ported barrel significantly reduces felt recoil, making the firearm feel 'flat' and easy to control. This allows the red dot sight to return to zero quickly after each shot, improving follow-up shot speed.

What are the key features of the ECM R11 Fuse grip module?

The ECM R11 Fuse grip module offers excellent ergonomics, feeling like a full-size handgun. It includes an integrated and funneled magwell for faster reloads and is designed to work with or without a thumb safety.

What are the pros and cons of the ECM R11 grip module's texture?

The ECM R11 grip module provides a secure hold, even in hot conditions, but some users might prefer a more aggressive texture. The grip panels appear to be swappable, suggesting potential for aftermarket options with different textures.
