I ordered the wrong one. Called H and K parts as to my mistake and within 6 days of my call I had the correct parts on my Mark 23. Great job.

I bought this for my sbr USC to use when I do not have a suppressor on the gun. Looks cool and keeps my threads safe. Excellent fit & finish

"Makes my HK45CT even more badass"

Tony Agustin on 12/22/2012 6:45:23 PM

Overall Product Rating:


When I first bought this I hated it. Sure it made my gun look somewhat 'tacticool', but I kept getting FTEs because of it.....or so I thought. Now thru trial and error (mostly error) and also from great advice from fellow veteran shooter, I realized it was ME. My technique was lousy as I was prone to limp wristing. Since I was a new shooter (the HK45CT was my first gun) I never was aware of it. Today at the range changed my perceptions of this flash hider and now I would recommend it whole heart... More details


"45 Pistol Flash Hider"

Richard Thedens on 10/12/2011 6:35:49 AMVerified

Overall Product Rating:


I got one of these for my USP 45 Tactical some years ago. Forget about the term flash hider. Instead think "accuracy enhancer". This four prong design vents the turbulent gasses and allows the bullet to fly through clean. undisturbed air. 3 inch groups turn into 2 inch groups at 25 yards. I think there is a 30% improvement. Partly due to an extra ounce on the end of the barrel...this thing WORKS


"no more muzzle flash"

david georgalas on 2/23/2013 9:32:54 AMVerified

Overall Product Rating:


Flash hider works excellent. no loss of sights due to flash. Faster follow up shots. Weight also helps calm recoil.


"hk usp45 full size flash hider"

michael felker on 3/31/2012 3:39:28 PMVerified

Overall Product Rating:


Hides the flash well and makes the pistol feel like a 100 times better weapon. The gun is better balanced and has much less recoil making it way more fun to aim and shoot.


"45 flash suppressor"

Shipping was fast, function and looks are great price is a little high but not to bad . Best part is it doubles as a close quarter weapon.
