Western Arms Colt Mk IV Series 70 GBB Pistol (Premium Edition)
 
This is a valuable piece that adorns the Colt Government Series 70, which boasts unparalleled perfection in the history of the Colt Government, with wooden grips and a premium bluing (blackening) finish.
Considered the golden standard of civilian 1911s, the Colt Mk IV Series 70 (produced from 1970–1983) is faithfully recreated by Western Arms (WA) with unmatched Japanese craftsmanship. Crafted from high-density Carbon Black Heavy-Weight resin with an authentic hand-blued finish and genuine rosewood grips, this classic Government Model captures the timeless elegance, deep 1970s roll markings, and substantial weight of the original .45 Auto.
Authentic 1970s Roll Markings: Reproduces the clean, well-balanced factory engravings of the golden-era Series 70, featuring classic Colt markings on the left side and crisp "GOVERNMENT MODEL" roll marks on the right.
Hand-Blued Carbon Black HW Finish: The Carbon Black Heavy-Weight slide and frame undergo matte blast-shot processing followed by side-flat polishing and WA's signature chemical bluing treatment, creating a deep, lustrous black-steel sheen impossible to achieve with standard paint.
Heavyweight Metal Barrel & Internals: Outfitted with a chrome-plated CNC brass outer barrel, a polished metal chamber cover, and a steel recoil spring plug and guide rod for realistic weight balance and crisp metallic operation.
Genuine Rosewood Full-Checkered Grips: Fitted with richly grained natural rosewood grip panels featuring traditional full checkering for a secure hold, warm tactile feel, and inlaid Rampant Colt medallions.
Proven WA Magna Blowback System: Built on Western Arms' renowned Magna gas blowback architecture, delivering snappy recoil and reliable cycling in a timeless, no-frills classic silhouette.
