FOR Systems Pluto 9

FOR Systems Pluto 9 Details

The FOR Systems Pluto 9 is the 9mm can for shooters who are done with boosters. It threads directly onto any 1/2×28 barrel, so there is no Nielsen device, no piston, and nothing extra to buy, index, or troubleshoot. At 4.5 inches long, 1.25 inches around, and roughly 2.5 ounces of Grade 5 titanium, it barely changes how your pistol carries, points, or holsters.

Features & Benefits

• Boosterless direct-thread design for 1/2×28 threaded 9mm barrels
• Grade 5 titanium construction at roughly 2.5 ounces
• Slim 1.25 inch tube stays out of your sight picture and fits many open-bottom holsters
• Compact 4.5 inch length keeps pistols and PCCs maneuverable
• Full-auto rated for 9mm with no barrel restrictions
• Graphite black C-Series Cerakote finish

It gives up a little hush to full-size cans, but for the size and weight, nothing about it feels like a compromise. Browse more 9mm suppressors, see the rest of the FOR Systems lineup, or check out the rimfire Pluto 22 that started it all.

Frequently Asked Questions

Does the Pluto 9 need a booster?
No. The Pluto 9 is a boosterless, direct-thread 9mm suppressor that mounts straight to a 1/2×28 threaded barrel with no Nielsen device, piston, or separate mounting system required. Thread it on, and it’s ready to shoot.

Will it run on a tilting-barrel pistol like a Glock?
Maybe, but it isn’t guaranteed. Tilting-barrel pistols like Glocks rely on the barrel unlocking and tipping during recoil, and adding suppressor weight to the muzzle without a booster (Nielsen device) can interfere with that unlocking motion and cause cycling issues. The Pluto 9’s light weight, about 2.5 oz, puts it in the category of boosterless cans that sometimes run reliably on tilting-barrel hosts, but reliability depends on the specific pistol’s recoil spring weight and the ammunition used. FOR Systems’ own product listing doesn’t publish a host-by-host compatibility list, so confirm with FOR Systems or your dealer for your exact Glock model and load before counting on boosterless operation.

What holsters work with it installed?
The Pluto 9 is built to work with open-bottom, suppressor-height holsters. Its slim 1.25″ diameter and compact 4.5″ length keep it compatible with more holster designs than a typical pistol can. Exact fit still depends on your specific host and holster combination, since overall length with the suppressor installed varies by pistol. Check with your holster manufacturer for suppressor-height clearance on your exact host before assuming a drop-in fit.

Is it full-auto rated?
Yes. The Pluto 9 is full-auto rated for 9mm.

Pluto 9 vs. Pluto .22 what is the difference?
Caliber is the main difference: the Pluto 9 is built for 9mm, and the Pluto .22 (sometimes searched as “Pluto 22″) is a rimfire can for .22 LR. Beyond that, the Pluto 9 is 4.5″ long, 1.25″ in diameter, and weighs about 2.5 oz, while the Pluto .22 is 5″ long, 1” in diameter, and weighs about 2 oz. Both use Grade 5 titanium construction and the same 1/2×28 direct-thread mount, so the choice comes down to which caliber you’re suppressing.
