Can Your Sig P365 Feel Like A 2011?! | ECM R11 Grip Module

Pistol modularity and the SIG P365 platform

The video opens with an overview of modular pistol design using the SIG P365 as the main example. The host explains that the P365 and P320 families use a removable fire control unit (FCU), which is the serialized component. By pushing out a pin, the FCU and trigger can be lifted out and dropped into different grip modules. A Glock frame is shown as a contrast, where the fire control components are embedded and the frame itself is serialized, so changing grip size effectively requires a new gun. This modularity allows the P365 user to swap between various grip modules, including the new ECM Precision R11, without replacing the entire firearm.

Design, features, and ergonomics of the ECM R11

The ECM Precision R11 is introduced as an all-metal grip module for SIG P365 variants, designed to give a feel similar to a 2011-style pistol. It is shown with an XMacro slide and can also accept a P365 XL slide; standard shorter P365 slides will not work. The R11 includes built-in gas pedals or thumb rests on both sides for left- or right-handed shooters, a built-in flared magwell with optional more aggressive versions, and side panels that slide in on tracks and can be swapped. The grip module is machined from aluminum and feels sturdy. The mag release is a metal, one-piece aluminum design, contrasted with the factory two-piece polymer release that can break under aggressive magazine insertion, illustrated by a broken OEM release on hand.

Comparisons to CZ Shadow and 2011-style pistols

The back of the ECM R11 grip is compared to the CZ Shadow series, particularly the CZ Shadow 2. The beavertail and tang area are angled in a way that encourages the hand to ride high, similar to the CZ, which is known for excellent ergonomics. This higher grip position is said to improve recoil management. The R11 also features a double undercut on the trigger guard and a subtle finger groove with a bottleneck shape to enhance purchase, though the host notes that feel is subjective. The front of the trigger guard is flat to avoid limiting weapon light or laser options, and a Picatinny rail is included. The company’s background in building 2011 pistols is emphasized, and the R11 is shown next to a MAC 9 from Military Arms Corporation to illustrate the intended 2011-like grip feel, even though the platforms differ.

Range test with P365 Fuse slide

At the range, the ECM Precision R11 is first tested with a P365 Fuse slide. The host focuses on how the integrated gas pedals index the support-hand thumb. With the finger off the trigger, the thumb naturally rests on the pedal, and during firing the shooter can actively press down to counteract muzzle rise. The metal construction of the grip module is noted for having no flex. During live fire, the pistol is described as staying very flat, with the gas pedal applying noticeable downward pressure on the muzzle. The host contrasts this with earlier impressions of the P365 Fuse, which felt snappy with its original frame. With the R11 installed, that snappiness is described as essentially gone, and the gun tracks flatter through strings of fire.

Range test with XMacro comp slide

The slide is swapped to an XMacro comp slide, which is shorter, lighter, and comped, and fits the R11 grip module more flush. The expectation is that it will shoot similarly to the Fuse setup. On the range, the gas pedal again stands out as the key feature, described as a “home run” for keeping the gun flat. After reviewing slow-motion or playback footage, the team notes that the muzzle appears very flat in recoil. Despite the XMacro slide being smaller and lighter, the perceived recoil and muzzle rise remain minimal. The host runs a fast magazine dump and reports rarely losing the dot in the optic window, only occasionally slowing down when it moves. The combination of the high grip encouraged by the beavertail and the aggressive gas pedal is credited for the stable sight picture.

Final impressions on recoil control and use cases

In closing, the host admits initial skepticism about the R11 frame, especially the sharp-feeling gas pedal when handled dry. After shooting, the perception changes, with the gas pedal described as extremely effective compared to low-profile or flimsy designs that do not offer a solid purchase. The designers’ experience with 2011s and competition shooting is highlighted as influencing the focus on keeping the gun flat and the dot visible in the glass. Potential downsides such as holster compatibility are briefly mentioned, as users may need to find holsters that accommodate the gas pedal and grip profile. The R11 is recommended for SIG P365 XL, XMacro comp, and Fuse configurations, but not for shorter P365 slides. The host suggests it can help shooters keep the pistol flatter and achieve more accurate hits, particularly in competitive contexts, and invites viewers to share experiences with similar frames or gas-pedal-equipped designs.
