40/357 P320 Compact Models

The 40 caliber model offers more challenges as far balancing the weight of the slide. 
This slide has been carefully designed to meet the weight required for the more powerful 40 and 357 rounds.

Norsso standard slide features:

  • Made with 17-4 Precipitation Hardened Stainless Steel
  • Special optic mount screws included
  • Stripped slide only; sights, optics, or other accessories shown are not included with purchase

Order a set of internals with your slide and our expert staff will install them for free!

    I am impressed! The craftmanship on this slide is superior! I mounted a Sig Sauer Romeo 2 on this slide and ran several hundred rounds thru it. This slide performed flawlessly. I give this slide *****5 STARS***** across the boards!

    The perfect slide

    Posted by Evan on Sep 19th 2022

    Makes my new p320 build totally pop. Love the DLC coating. Norsso has the only options other than the stock Sig slide for a .357/.40 compact build.

    Norsso Team, Thank you all so much for this awesome slide & suppressor height sights! I knew I’d love it based on the way it looked on videos but I am completely blown away by the craftsmanship and aesthetic of the slide! I looked carefully for the slightest scratch or blemish and found not one. I couldn’t recommend this product enough for those who take the time to read this review. You will surely love this item! Bonus points for getting it shipped a whole day ahead of schedule! Love you guys!

    Truly fantastic craftsmanship. Beautiful finish. I’ve used it with my FCU and a couple different grips. The fit is flawless with both original sig internals and Grey Ghost Precision. Very high quality. Impressive
