We have tuned our X-OST porting to offer reduced muzzle flip and felt recoil while maintaining reliability using 9mm 115gr  FMJ.

***This package only includes slide and barrel porting. 

Coating will be required after machine has been performed to prevent the bare metal from rusting. Please see our Cerakote option in our store for pricing. If your order is placed and no Cerakote option has been added, we will send your slide back you with the bare metal exposed. 

X-OST can be added to any of our slide milling packages or an OEM slide.
