Big bore pistol cans have a reputation for turning your handgun into a boat anchor, and the JK 155 RPX 46K exists to put that reputation to rest. This is the shortened K variant of JK Armament's RPX 46 platform, keeping the same advanced Rifle Pistol System baffle geometry from the full-size can but packaging it into a compact 1.55 inch diameter tube that feels balanced on a .45 ACP handgun instead of hanging off the end of it. You still get JK's Tone Technology, which shapes the sound signature into that deep, solid report the RPX line is known for, rather than the sharp crack cheaper cans produce.
JK builds these around a Mission Configurable baffle stack, meaning you can add or pull baffles to change the length and weight of the can without any specialized tools. Run it short for a compact carry-friendly setup, or stack it longer when you want every bit of suppression on the range. The RPX 46K also uses the industry-standard HUB 1.375×24 mount, so pistons, boosters, fixed mounts, and tri-lug adapters from across the market will thread right on.
The blast baffle is Grade 5 titanium, the part of the can that takes the most abuse, while the modular baffles are machined from 7075 billet aluminum to keep overall weight down. That combination is why the RPX platform carries full-auto ratings on handgun calibers while staying light enough for everyday use.
With its .46 caliber bore, this can is at home on .45 ACP pistols first and foremost, but the oversized bore means your 10mm, 9mm, and other smaller pistol calibers can run through it too. It is American made and backed by JK Armament's unlimited, unconditional lifetime warranty, which is about as straightforward as suppressor coverage gets. If you want one can that covers your big bore pistols without the usual bulk, this is a smart place to land.
If your host is a typical tilting-barrel semi-auto like a 1911 or Glock 21, yes, you will want a piston booster assembly so the pistol cycles reliably. The RPX 46K uses the industry-standard HUB 1.375×24 mount, so JK's own HUB Piston Mount with a .578×28 piston is a natural pairing. Fixed-barrel hosts like pistol caliber carbines can run a direct thread mount instead.
Yes. The .46 caliber bore gives it room for smaller pistol cartridges too, so 10mm, .40 S&W, 9mm, and similar rounds can all run through it with the right mount. Keep in mind that a larger bore over a smaller bullet gives up a little suppression compared to a dedicated can, but the flexibility is the whole point of the RPX design.
The baffle stack is user configurable, so you can add or remove baffles to change the overall length and weight without specialized tools. Run it short when you want a compact, maneuverable setup, or build it out longer when maximum sound reduction matters more than size. It is the same Mission Configurable approach JK uses across its 155 series.
JK Armament backs the RPX 46K with an unlimited, unconditional lifetime warranty. There are no hoops to jump through or fine print about approved ammo lists, which is a big part of why the brand has built such a loyal following. These cans are also machined in the USA.
