Frequently Asked Questions

How do the different spacers alter the pistol's recoil dynamics?

The spacers alter the buffer resistance when the slide is fully open. The short spacer provides 14.3 lbs of resistance for a lighter slide feel, the medium spacer provides 18.7 lbs, and the long spacer provides the strongest 21 lb buffering effect to absorb maximum impact.

What function do the three interchangeable external springs perform?

The external springs (Short, Medium, Long) control the rate at which the slide returns forward into battery from the idle/closed position, allowing you to fine-tune cycling speed according to your ammunition power factor.

Will this system fit a Stealth Arms Platypus with a Bushing Barrel?

No, this system (MPN: MS-STL/2) is engineered specifically for the 5" Bull Barrel configuration of the Stealth Arms Platypus.

Are installation tools included with this kit?

Yes, the package includes a spring plug, a red pressure-plate tool, and a metal cup-screw tool to make assembly and adjustments straightforward.
