The AAC Ti-RANT 45 is the world's first silencer for .45 ACP pistols that is truly stealthy when fired dry. The average dry sound signature of the Ti-RANT .45 is 133 dB when fired on a Heckler and Koch USP Tactical .45 with Remington 230 grain ammunition. This puts the dry performance of the Ti-RANT .45 squarely in the ballpark of most competitor's 9mm pistol silencers. With a wet charge of 5cc's of water, the sound signature drops to 125 dB. To put it another way, our .45 silencer is quieter than some company's .22 silencers. The Ti-RANT .45 does not stand out among a sea of posers just because of its jaw-dropping performance. Intelligent material selection gives the Ti-RANT .45 unequalled durability in a deceptively light-weight package. The Ti-RANT .45 incorporates AAC's new A.S.A.P. CLUTCH. This highly evolved Nielsen device enables flawless semi-automatic operation on all relevant host pistols, and can be fully disassembled for cleaning or piston replacement with no tools in seconds. The Ti-RANT .45 can be outfitted with pistons threaded M16 x 1 Right Hand, M16 x 1 Left Hand, and two pistons threaded .578-28; one extended for the Sig P-220 and 1911's with a full length guide rod, and a flush mount for 1911's with a standard G.I. guide rod. For multi-caliber use, pistons are available in the most common 9mm and .40 thread patterns to allow use of the Ti-RANT 45 on hosts in those calibers.
