Icarus Precision
Icarus Precision builds the A.C.E. line of aftermarket grip modules for modern chassis-based pistols — the Sig Sauer P320 and P365, Springfield Echelon, Zev OZ9, and Ruger RXM. Because these pistols separate the serialized fire control unit from the grip frame, a shooter can drop the factory FCU into an Icarus grip module and change the entire feel of the gun without any gunsmithing. The 7075 aluminum A.C.E. modules add texture, a Picatinny rail, and a re-contoured beavertail, while the polymer A.C.E. Air trims weight and cost for the same ergonomic upgrade.

How Icarus Precision Grip Modules Work
Pistols like the Sig P320, Sig P365, Springfield Echelon, and Zev OZ9 are built around a removable, serialized fire control unit (FCU) rather than a fixed frame — the FCU is the actual "gun" under the law, and the grip module around it is just a chassis. Icarus Precision makes replacement chassis for these platforms, so a shooter can drop their existing FCU into an Icarus grip module and get a completely different grip angle, texture, and rail setup without any gunsmithing or paperwork.
A.C.E. Aluminum Grip Modules
The standard A.C.E. modules are machined from 7075 aluminum with an anodized finish, a Mil-Std 1913 Picatinny accessory rail, and horizontal texture at the front strap, back strap, and sides for a more secure grip under recoil. A deep undercut trigger guard lets the shooter get a higher grip, and a modified beavertail helps control muzzle flip — all while staying compatible with OEM Sig magazines and baseplates.
A.C.E. X and A.C.E. SOCOM: Platform-Specific Options
The A.C.E. X is built for the Zev OZ9 X and Springfield Echelon Compact, and the A.C.E. SOCOM is sized specifically for the Sig P320 Full Size and Carry frames, both with the same aluminum construction and texture pattern as the standard A.C.E. line. Choosing the right variant comes down to matching the module to the exact frame size and FCU you're running — not every A.C.E. module fits every P320 or P365 configuration.
A.C.E. Air: The Polymer Option
The A.C.E. Air brings the same ergonomic improvements to a polymer construction at a lower price and lighter weight than the aluminum modules, available with or without a thumb ledge depending on shooting style. It's the practical choice for a shooter who wants the Icarus grip angle and texture without the cost of a billet aluminum chassis.
Other Icarus Precision Upgrades
Beyond grip modules, Icarus Precision sells a double-stack 1911 grip, an A.C.E. magwell for the Ruger RXM and Zev OZ9, and an extended magazine release for the Sig P365 — smaller upgrades for shooters who want to fine-tune an existing grip rather than replace it entirely.
Frequently Asked Questions
Do I need a gunsmith to install an Icarus Precision grip module?
No — on FCU-based pistols like the P320, P365, and Echelon, the fire control unit drops into the new grip module without any fitting, since the module isn't the serialized part of the gun.
What's the difference between the A.C.E. and A.C.E. Air?
The A.C.E. is machined from 7075 aluminum; the A.C.E. Air is polymer, offering the same ergonomic upgrades at a lower weight and price.
Will an Icarus grip module fit my Sig P320 magazines?
Yes — Icarus grip modules are built to stay compatible with OEM Sig magazines and baseplates.
Does Icarus Precision make anything besides grip modules?
Yes — extended magazine releases, magwells, and a double-stack 1911 grip for shooters who want smaller, targeted upgrades.
