The Springfield XD and XDm: series pistols are rugged, reliable, and deliver match-grade components and match-grade accuracy for a price we can live with. They are true “tack-drivers right out of the box”! And our quality .460 Rowland® upgrades almost double their muzzle velocity, more than triple their power level and dramatically increase their range and accuracy! The Springfield XD 4" Service Pistol: Just like the larger Springfield XD 5" Tactical, the XD 4" Service Pistol is also our standard; and when fitted with your Authentic .460 Rowland® conversion, this accurate, rugged, reliable, lightweight, high capacity .45 caliber handgun will give you true .44 Magnum ballistics with less recoil, muzzle flip, noise, or muzzle flash than the legendary .44 Magnum alternative.
If you love your XD 4” Service Pistol now... you'll really love it in .460 Rowland®! Ported .460 Rowland® Conversions: Our unique .460 Rowland® porting system was developed to conform to California’s strict prohibition against “assault weapons”. Our fully compensated conversions do a better job of reducing recoil, muzzle flip, and flash; however, the ported conversion has the incidental advantage of being completely removable, without having to detach the screw-on compensator. Our Unique and Proprietary products are Often Copied but Never Duplicated, so don’t be fooled by fraud. Look for our Federal Trademark Insignia, (®), to be sure. The conversion includes a .460 Rowland® Increased Power Magazine Spring. We stand behind our products "®"; so, try them and love them ... or return them for repair, replacement, or refund.
