The Island Barrel Conversion is a full structural conversion that reworks the slide and installs a purpose-built island barrel assembly for race-ready performance, improved ejection, and a refined sighting platform. This is extensive machining and precision fitting — not a simple swap.

Important: This service requires the complete build and includes Overhaul & Fit (disassembly/reassembly, function check, and insured return shipping).

What’s Included

• Welding closed original sight dovetail on the slide

• Flattop widening to 0.400" where required

• Machining the slide to accept the island barrel assembly

• Custom-fit barrel to frame and slide for correct lockup

• Matched barrel (included)

• Barrel link & pin (included)

• Flush-cut reverse crown muzzle

• Sight dovetail milled in the barrel with solid front sight installed

• Barrel porting (optional — specify if you DO NOT want porting)

• Recoil spring selection & fitment for optimal function

• Cerakote on the complete slide (single color) included

• Overhaul & Fit included (safe disassembly/reassembly, function test, and insured return)
