SAI Tier One Package on Glock 19X

The SAI Tier One Package is now available on the Glock 19X - the ultimate package for performance and reliability on your Glock.  The Tier One Package on a Glock 19X features a trued mating of the frame and slide for optimal smooth tracking.  This smooth and fast tracking is further enhanced through the reliable SAI weight reduction on the slide which is taken to the edge with the addition of window cuts on the slide - only available on Tier Ones.  The slide features enhanced rear cocking serrations for positive manipulations and the additional positive cocking serrations for press checks.  The frame features a full hand stipple and double trigger guard undercut providing the user with a higher grip and added enhanced stippled surface for control.  Customers have their choice of flat or traditional trigger shoes, and have their choice of TiN or Black Nitride SAI Box Fluted Match and threaded barrels - all standard on Tier One Package.
