Description
Running a Ghost 45 or Wolfman on a fixed-barrel gun with the booster still installed is leaving performance on the table. Boosters exist to help browning-action pistols cycle, and on a fixed barrel they just add length and moving parts you don't need. This Dead Air fixed mount swaps in for the whole booster assembly, piston and spring included, giving you a shorter, simpler setup that threads straight onto a .578-28 muzzle.
Why Swap Your Ghost 45 to a Fixed Mount
The math is simple: one solid steel mount replaces three components. That means less overall length hanging off your muzzle, better balance, and nothing extra to keep track of when you break the can down for cleaning. You could get similar results by pairing a piston with a fixed barrel spacer, but the dedicated fixed mount keeps the package tighter and the install cleaner. It threads into the P-Series interface on the back of the can, so swapping between your pistol booster and this mount takes a minute, not an afternoon.
Where the .578-28 Version Fits
The .578-28 thread pitch is the standard for .45 ACP barrels, which makes this the go-to option for fixed-barrel hosts like a .45 Kriss Vector or a large-format pistol build running that thread. It also plays well beyond the Ghost 45 and Wolfman. Dead Air lists compatibility with the Mojave 9, Mojave 45, and RXD910Ti, plus the Primal when you add a P-Series adapter, so one mount can cover several cans in the safe.
A Small Part That Earns Its Keep
Finished in black with a low-profile footprint, this mount does its job without drawing attention to itself. It weighs next to nothing, holds zero on the host, and stays put shot after shot. If your suppressor spends most of its life on a fixed-barrel gun, this is one of those quiet upgrades you'll wonder why you waited on.

Frequently Asked Questions
Does the Ghost 45 fixed mount replace the booster assembly?
Yes, that's the whole point of it. The fixed mount takes the place of the complete booster assembly, both piston and spring, on your Ghost 45 or Wolfman. That shortens the overall length of the suppressor and cuts down on the number of parts you have to manage.
What suppressors work with this .578-28 fixed mount?
It uses Dead Air's P-Series mounting interface, so it fits the Ghost 45, Wolfman, Mojave 9, Mojave 45, and RXD910Ti. The Primal will also accept it if you add a P-Series adapter. Any Dead Air pistol can built on the P-Series interface is fair game.
When should I use a fixed mount instead of a piston?
Use the fixed mount on fixed-barrel hosts, meaning guns where the barrel doesn't recoil, like pistol-caliber carbines, AR-9s, the Kriss Vector, and similar platforms. A booster is only needed on tilting-barrel handguns to help them cycle. On a fixed barrel, the fixed mount gives you a shorter, more solid connection.
Why choose this over a piston with a fixed barrel spacer?
Both approaches work on a fixed barrel, but the dedicated mount is the cleaner solution. It's a single piece instead of a piston, spring, and spacer combination, and it keeps the suppressor's overall length shorter. Fewer parts means less to lose and less to fiddle with during cleaning.
