Caliber Ratings Based on Configuration:

Current Generation Resistance Suppressors feature 7075 billet aluminum tube housings which are extremely strong. As such we are able to rate our pistol suppressors for many high pressure rifle calibers for sporting use. (sporting use by our definition is 5-7 rounds of fire followed by allowing the suppressor to cool back to ambient temp). This sporting use allows much more flexibility with Griffin pistol suppressors than almost any other market options. Whether target shooting or hunting, Griffin pistol suppressor durability adds a dynamic to the pistol suppressor class of products not commonly found on the market. 

With Mini Blast Shield or A2 mount adapter :

  • *300 BLK Super 9"
  • *5.56mm 12.5"
  • *7.62x39 14.5"
  • *.308 WIN 18"

With 3 Lug mounts or Plan A:

  • 300 BLK Sub 8"
  • *300 BLK 16" Super
  • *5.56mm 16"

* Denotes sporting use only ( 5-7 rounds of fire followed by allowing the suppressor to cool back to ambient temp). Exceeding temperatures can compromise the strength of the tube material over time and is not recommended or warranted.  

Resistance Suppressors require no minimum barrel length restrictions or constraints for pistol calibers.

    Resistance Versatility!!!

    Published by Neal Chianese on 9th Oct 2018

    The Resistance 45 is the most versatile can I have ever purchased. I run it on an FNX 45 Tactical, Glock 23 40, Glock 26 9mm and with the addition of the Griffin Armament Taper Mount Minimalist Brake replacing the A2 flash hiders on my SBR's run it on an 8.5" 300 BLK both super and sub and a 14" 556. I change out the booster assembly with the Minimalist Blast Shield on the back of the can. The 300 BLK with subsonics is Hollywood quiet and I haven't even changed out the 45 end cap! I don't push the suppressor with supers; keep it to sporting/hunting use and make sure you let it cool. Great products and BIG Thumbs Up to Griffin Armament!!!

    Can't wait for my Stamp!

    Published by Ross Dillon on 6th Aug 2018

    I researched a lot of silencers, but this one jumped out as a great value, a perfect blend of functionality and cost. All parts and tools are included for a right-out-of-the-box solution. Adding a 9mm piston and Taper Mount Rifle conversion kit and I'll be good to go for a while!
