The 17-4 stainless steel construction provides a superior strength-to-weight ratio and consistent heat treatment, reducing wear on critical locking surfaces. The Nitride finish, a salt-bath ferritic nitrocarburizing process, creates a surface harder than chrome while being lubricious. This combination directly supports reliable cycling and extended service life, especially under high-volume 9mm training or competition use.
