SIG P211-GTO Review: 500 Rounds and Which Variant to Buy

article · review · Aug 12, 2026

Overview

The Holosun 507COMP features an oversized window designed for competition and fast target transitions. Holosun's Performance Reticle System offers a 2 MOA dot plus 8, 20, and 32 MOA circles, selectable on their own or as circle-dot combinations for different engagement styles. The large viewing window maintains peripheral awareness during recoil and rapid transitions while still allowing precise aiming at distance.

Built with a 7075-T6 aluminum housing, the 507COMP handles recoil from platforms ranging from PCCs to 12-gauge shotguns. The side-loading battery tray allows CR1632 changes without removing the optic or losing zero. Lock mode prevents accidental brightness or reticle changes during use.

The 507COMP has found a following across competition, home defense, and tactical applications where a wide field of view and fast target acquisition matter more than compact form factor.
