The Impuls-45-M is B&T's modular titanium pistol suppressor for .45 ACP and 10mm. The M is for modular: a detachable extension module lets you run it short at 6.7 inches and 8.4 ounces, or long at 8.8 inches and 10.4 ounces, depending on whether you're prioritizing suppression or handling on any given day. It ships with the .578x28 Impuls device and a booster. B&T part number SD-Impuls-OLS-45-M.

Two Suppressors in One Stamp

Modularity on a pistol can is more useful than it is on a rifle can. Run the full-length configuration on the range or for maximum suppression; pull the extension module and run the short configuration when you want the pistol to still holster, balance, and point like a pistol. One tax stamp, two guns' worth of capability. B&T also notes the design is adjustable for point of impact.

Booster Included

A tilting-barrel pistol needs a booster — a spring-loaded piston that lets the barrel unlock and cycle normally with the added mass of a suppressor hanging off the muzzle. Without one, most semi-auto pistols will short-stroke or fail to cycle entirely. The Impuls-45-M ships with the booster included, which is not universal in this category and saves you a separate purchase.

Printed Titanium

The Impuls-45-M is built from titanium via laser bed fusion as a weldless structure. Printing the suppressor as one continuous piece eliminates the weld seams that are the traditional failure point, and titanium keeps a .45-caliber can light enough to live on a pistol. Finish is Type 2 anodized gray.

Who This Suppressor Is For

.45 ACP and 10mm shooters — a smaller crowd than the 9mm market, and therefore a group that is chronically underserved by suppressor makers. .45 ACP is subsonic straight out of the box in most loadings, which makes it one of the genuinely quiet suppressor host cartridges. Pair this with a 1911, a Glock 21, or a 10mm hunting pistol.

B&T Suppressor Warranty

B&T states: "If your suppressor becomes non-functional or damaged during non-negligent use, we will be replacing your suppressor free of charge." Discontinued models are eligible for an upgrade to the appropriate generation equivalent. Handloads, incorrect-caliber ammunition, bore obstructions, and unauthorized repair attempts are excluded.
