The Silencerco Osprey is by far our best selling pistol suppressor. The lightweight suppressor is set apart by its oblong shape. The majority of the mass hangs below the barrel. While not the absolute quietest suppressor available for some calibers, the advantage of the Osprey’s unique shape is that you don’t need to replace standard sights on guns you want to suppress. Most firearms, including many with factory threaded barrels, come with standard height sights. A traditional cylindrical suppressor blocks the view of the target. Suppressor ready sights for many guns run up to (if not over) $200! Replacing sights on a couple of guns adds up quickly. The Osprey solves this problem with the oblong shape. We sell mostly .45 caliber Ospreys, because there are pistons available for other calibers, such as 9mm, .40SW, .380ACP, and so on. By purchasing the larger caliber suppressor, you are able to switch between more guns. However, the Osprey is also available in 9mm, .40SW, and the .45K, which is a shorter version of the .45. We carry many suppressor ready guns, including the Sig Sauer 1911R, Smith & Wesson M&P45, the FHN FNX-45 Tactical, and the Glock 19.
