Piston vs Pistonless 9mm Suppressors: Reliability Test
Piston vs Pistonless 9mm Suppressors: Reliability Test. Piston or pistonless silencer for your P320 or Glock? We test both designs side-by-side with subsonic ammo to find which actually cycles reliably on centerfire { "@context": "https://schema.org", "@graph": [ { "@type": "Organization", "@id": "https://greyhive.com#organization", "name": "Greyhive", "url": "https://greyhive.com", "description": "Greyhive is a censorship-resistant video platform for the firearms, 2A, hunting, and outdoor industries — where creators build, review, and monetize unfiltered content.", "logo": { "@type": "ImageObject", "url": "https://greyhive.com/static/uploads/images/ae198483-01c9-44b4-a16a-03f516ceaf66.svg", "width": 512, "height": 512 }, "sameAs": [ "https://x.com/greyhive", "https://www.instagram.com/greyhive/", "https://www.youtube.com/@Greyhive", "https://www.linkedin.com/company/greyhive/" ] }, { "@type": "WebSite", "@id": "https://greyhive.com#website", "url": "https://greyhive.com", "name": "Greyhive", "description": "Greyhive is a censorship-resistant video platform for the firearms, 2A, hunting, and outdoor industries — where creators build, review, and monetize unfiltered content.", "publisher": { "@id": "https://greyhive.com#organization" } }, { "@type": "Person", "@id": "https://greyhive.com/c/black_rifle_medic#person", "name": "Black Rifle Medic", "url": "https://greyhive.com/c/black_rifle_medic", "description": "Black Rifle Medic is a Greyhive creator producing original 2A, firearms, hunting, and outdoor content.", "image": "https://greyhive.com/lazy-static/avatars/5dbcacb3-ffa8-456c-b56d-7a803d8dfd54.jpg" }, { "@type": "Article", "@id": "https://greyhive.com/blog/piston-vs-pistonless-9mm-suppressors-test#article", "isPartOf": { "@id": "https://greyhive.com#website" }, "mainEntityOfPage": { "@id": "https://greyhive.com/blog/piston-vs-pistonless-9mm-suppressors-test" }, "url": "https://greyhive.com/blog/piston-vs-pistonless-9mm-suppressors-test", "headline": "Piston vs Pistonless 9mm Suppressors: Reliability Test", "name": "Piston vs Pistonless 9mm Suppressors: Reliability Test", "description": "Piston or pistonless silencer for your P320 or Glock?

The short answer from Black Rifle Medic's side-by-side test on Greyhive: a piston-equipped can is the reliable default on a tilting-barrel pistol, and a pistonless suppressor will run only if you're willing to tune the host gun to make it run. In a 4-minute live-fire comparison, Black Rifle Medic ran the same ammunition — Federal Syntech 150-grain 9mm — through two very different cans on two very different hosts: a pistonless compact suppressor (referred to in the video as the Pluto 9) and a Resilient RSP running a piston. Host guns were a SIG P320 with a completely factory recoil spring and a Glock 17 with a reduced-power recoil spring installed. The results split cleanly along the spring line, not the brand line. That distinction matters more than any marketing copy on either can, and it's the thing most suppressor buyers don't learn until after the tax stamp clears. Key Takeaways The pistonless Pluto 9 would not cycle reliably on a SIG P320 running its factory recoil spring with Federal Syntech 150-grain 9mm. Swapping to the Resilient RSP with a piston on the same P320, same ammo, produced what Black Rifle Medic called \"much more reliable\" function. On a Glock 17 with a reduced-power recoil spring, the pistonless…
