Duration: 26:21

This guide details the modification process for converting an FNX-45 pistol to fire the .460 Rowland cartridge, as demonstrated by an expert firearms instructor. Key steps involve reaming the barrel, upgrading recoil and magazine springs, and installing a compensator to handle the significantly increased pressure and slide velocity. The instructor emphasizes that polymer frames are better suited for this high-pressure round due to their flex.

Quick Summary

The .460 Rowland is a high-performance semi-automatic handgun cartridge operating at approximately 40,000 PSI, delivering over 800 ft/lbs of muzzle energy. Conversions, like on the FNX-45, require a heavier recoil spring, upgraded magazine springs, and a compensator. Polymer frames are ideal due to their ability to flex under extreme pressure.

Frequently Asked Questions

What makes the .460 Rowland a powerful handgun cartridge?

The .460 Rowland is a powerhouse due to its extremely high operating pressure, reaching around 40,000 PSI. This allows it to propel heavier bullets at significantly higher velocities, generating impressive muzzle energy exceeding 800 ft/lbs with a 185gr bullet.

What modifications are needed to convert an FNX-45 to .460 Rowland?

Converting an FNX-45 to .460 Rowland requires reaming the barrel for the longer case, installing a heavier recoil spring (around 24 lbs), upgrading magazine springs, and fitting a compensator to manage the increased slide velocity and pressure.

Why are polymer frames preferred for .460 Rowland conversions?

Polymer frames are preferred because they flex under the extreme pressures of the .460 Rowland (40,000 PSI). This flexibility helps absorb some of the stress, making them more durable and less prone to cracking than rigid steel frames over time.

What kind of ammunition is recommended for .460 Rowland in self-defense or hunting scenarios?

Due to the high velocity of the .460 Rowland, standard hollow-point bullets can fragment. For dangerous game or deep penetration needs, solid copper 'Extreme Penetrator' style rounds are recommended to ensure effectiveness without breaking apart.
