$1,500.00 USD
$1,500.00 USD
Sale Sold out

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)

Eligible Platforms

  • Barrel lengths: 3.9", 4", 4.1", 4.25", 4.4" (all variations)

  • Full-dustcover and full-size platforms such as STI full size 5", Rock Island, Prodigy Gen 1 5", and similar 1911/2011 slides in 9mm / .38 Super / .40 S&W / .45 ACP / 10mm

  • If you’re unsure about compatibility, contact us first and include clear photos

Not Eligible

  • Slides with existing internal lightening cuts

  • Comp-block guns or sight-block style slides

  • Any non-1911/2011 platforms

Turnaround & Lead Time

  • Minimum 12 weeks from date received — this is a high-complexity, custom conversion; lead times may vary with demand.

Important Notes

  • This is a permanent, structural modification and is not reversible.

  • If other parts are finished in PVD/DLC/TiN and you want them retained or re-finished, add the appropriate surface treatment at checkout.

  • All machined and coated areas are subject to normal wear over time, especially in high-contact zones.

  • We perform final function testing and inspection before return.

Shipping & Returns

If you order a product from DSC, we will stand by our product and correct/fix an issue if it may arise. Please note, no returns are accepted on custom barrel services/products or used drop-in barrels.

Return shipping may be asked for or necessary for projects that require sending in completes rather than parts - this is to insure proper insurance in the return shipping process.

DSC Drop In Barrels

DSC barrels are designed for drop-in installation, in conjunction with factory counterparts such as factory slide stop and recoil - we continuously strive to improve the quality of our drop-in barrels as each style and variant is custom-made, hand fitted to shop models, and coated per order. 
Turnaround times are estimated to be approximately 5-7 weeks after the initial purchase, though they are subject to change depending on the situation. *Stainless variants may ship sooner, depending on the order. 
**In the unlikely event that you experience any issues with installing your barrel, we offer free custom fitting.
