Bastion Slide Back For Glk Cross

The Bastion Slide Back For Glock Cross is a precision-engineered aluminum slide back plate designed to enhance the aesthetics and functionality of compatible Glock pistols. Machined from T6 aluminum to exacting tolerances, this slide back plate delivers the fit and finish expected by users who demand reliability in their duty, training, and recreational firearms.

Each plate is manufactured using precision machining processes that ensure tight tolerances and consistent geometry across production runs. The hard coat anodized finish provides corrosion resistance and durability in field conditions, while the laser engraving adds legible marking and personalization options. T6 aluminum construction balances lightweight design with structural rigidity, resisting flexing or warping under normal use. This material choice is standard in high-end firearm accessories where weight savings and durability must coexist.

This slide back plate is compatible with Glock models 17–41 across generations 1 through 4, covering the full range of full-size and compact Glock duty and training platforms. Users upgrading their firearms with custom components, personalizing their carry or duty weapons, or building out a training setup will find this plate a straightforward installation that adds visual character without compromising function. The plate suits patrol officers, competitive shooters, range instructors, and civilian operators seeking quality aftermarket upgrades.

Bastion's reputation in the tactical accessory market rests on adherence to tight manufacturing tolerances and durable anodizing processes. Slide back plates are small components, but their fit directly impacts user confidence. The hard coat anodize specification indicates a thicker, harder anodic layer than standard type II finishes, extending service life in high-use environments and corrosive conditions.
