Fit and finish on both production units is fantastic, while cosmetic features like the spoke pattern on the muzzle end cap and grasping grooves on the booster assembly reinforce the impression that this is a finely crafted instrument.

AAC (Advanced Armament Corp.) is well known for pushing the edge of suppressor design. They make extensive use of titanium alloys in their rifle suppressors, but this is the first pistol suppressor I know of that uses the exotic metal.

AAC sent me both the .45 ACP and 9mm Ti-Rant. When I asked about the use of titanium in a pistol suppressor, they said, “Titanium is stronger than aluminum, so we were able to run a thinner tube — so much thinner that we saved weight over an aluminum tube of the same strength. This thinner tube allowed us to maintain the same 1.38 inches outer diameter of the Evo 45 and still netted us a larger inside diameter. That means larger baffles and more internal volume (both improve sound performance). Corrosion resistance played into this as well. When you know a silencer is going to be shot wet a good bit (like a handgun silencer) using corrosion resistant material is also smart.” In conclusion, they added, “And it’s cool!”


.45 Ti-Rant
The .45 Ti-Rant weighs 11.5 ounces and measures 8.74 inches in length. That does not make it the lightest or shortest, but it is one of the quietest — providing an incredible 41-decibel (dB) reduction in the wet mode—even dry it’s still as quiet as many 9mm cans are wet. I found the performance nothing short of amazing. The recoil booster system provided flawless performance on three different 1911’s. Interchangeable pistons allow for threads of M16 x 1 both RH and LH, plus the standard of .578 x 28 for 1911 pistols. Further, a short 1911 piston reduces overall length when the standard recoil spring system is installed. an extended piston is available to deal with full-length guide rods.

The .45 Ti-Rant weighs 11.5 oz and measures 8.74″ in length — incredibly quiet, providing an incredible 41db reduction is the wet mode.

The booster system comes apart for cleaning or maintenance with no tools required. It is also capable of indexing to 10 different positions, a feature that can be used to adjust point of impact shifts when employing the suppressor. The diameter is large enough to obscure standard height sights, but I’ve never found that to be much of an issue. Using a front night sight with white ring on the insert, such as the Novak type, permits a fine sight picture. While you can’t actually see the target behind the sights, at normal handgun ranges you still see the target around the slide/suppressor. If you find that to be distracting, you’ll need to get a high set of sights installed, perhaps .250 at the front blade as opposed to the standard .175, then a corresponding rear sight.
