.960 Rowland® 9mm Conversion — Magnum Power for Your Pistol

Convert your full-size 9mm (4″ barrel or longer) to cycle .960 Rowland for true .357 Magnum performance — all for just $223.
Your barrel will still cycle standard 9mm reliably, with no loss of accuracy or function.

⚠️ Note: We strongly recommend sending a bare stainless steel barrel for conversion. While some coatings are purely cosmetic, many factory barrels are case-hardened or nitrided, which causes excessive wear on our tooling and can affect the final result. Stainless barrels without surface hardening produce the best outcome.

Barrels under 4″ (subcompacts) aren’t usually suitable — their recoil assemblies and slide weights aren’t always up to the task of cycling .960 Rowland.

How it works:
Place your order, ship us your barrel with your name and order number, and we’ll handle the conversion.
