Pistol caliber suppressors get dirty. Fast. That is just the reality of shooting .45 ACP suppressed, and it is exactly why the Maxim Defense MS-45 was built around easy serviceability. The whole can comes apart with basic tools you already have in the garage, and the 17-4 stainless steel baffles shrug off repeated cleanings without complaint. No sending it back to the factory, no special proprietary wrenches, just take it apart, scrub it, and put it back together.
The modular design is the other half of the story here. Run the MS-45 in its short configuration at 6.53 inches and 10 ounces when you want a compact package on a carry-sized pistol, or stretch it to 8.64 inches and 12 ounces when you want maximum sound reduction. Either way you are working with a slim 1.375 inch outer diameter that stays out of the way of most sight setups. The 7075 aluminum tube keeps overall weight down while the stainless core handles the heat and blast where it matters.
Out of the box you get a .578×28 piston, which covers the most common thread pitch on .45 ACP threaded barrels. The booster assembly is built on the well-proven Dead Air P Series pattern, so it cycles reliably on tilting-barrel pistols and swapping pistons down the road is simple. The black DLC and hard coat anodized finish holds up to solvents, carbon, and general range abuse.
Maxim Defense made its name building gear for hard use, and the MS-45 follows suit with a full-auto rating and no fussy round-count babying required. For anyone running a threaded .45 pistol who wants one can that adapts between compact handling and full-length quiet, this is a smart way to do it. Suppressed .45 ACP is naturally subsonic with standard loads, which makes this pairing one of the most pleasant shooting experiences you can have.
The MS-45 ships with a .578×28 piston, which is the standard thread pitch for most .45 ACP threaded barrels, so it will mount right up to the majority of threaded .45 pistols. The booster assembly handles the cycling on tilting-barrel designs like 1911s and striker-fired pistols. Just double check your barrel's thread pitch before ordering.
In the short setup the MS-45 measures 6.53 inches and weighs 10 ounces, giving you a more compact, handier package. The long configuration runs 8.64 inches at 12 ounces and delivers more sound reduction. Swapping between the two is straightforward since the whole can disassembles with common tools.
This is one of the MS-45's strong suits. It comes apart with basic hand tools, and the 17-4 stainless steel baffles can handle aggressive cleaning methods that would eat up aluminum internals. Since .45 ACP is a dirty, low-pressure cartridge, regular cleaning keeps the can performing at its best, and Maxim made that job about as painless as it gets.
Yes, the MS-45 carries a full-auto rating and multiple sources list no barrel length restrictions, so it handles high round counts without issue. It ships configured for handguns with the .578×28 piston, and it does not include a fixed-barrel PCC mount in the box, so plan on picking up the appropriate mount separately if you want to run it on a carbine.
