Rail-Mounted Suppressor Doesn’t Need Threaded Barrel

This unique can from Germany uses an accessory rail instead of a threaded barrel to attach to a handgun.

Have you ever seen the unique rail-mounted suppressors from Fischer Development for Glock and H&K pistols?

It’s a pretty wild concept that was showcased a couple years ago at various gun industry shows. The rectangular suppressor attaches to the accessory rail of a handgun with a simple click, and doesn’t actually attach to the barrel at all.

Some wonder how something like this could be effective, and you'll find plenty of arguments on social media and Reddit about whether or not rail-mounted compensators or bushing compensators really do anything because they don't create a strong seal around the muzzle. (I'll go on record as saying they do make a difference.)

Well, if the video of the FD919 suppressor above is to be believed, it certainly does make a difference. Plus, the ability to attach and detach it so quickly, without having to buy a new threaded barrel for your existing handgun, is certainly attractive.

Also, it’s low-slung design means you can use the regular sights on the handgun without replacing them for taller sights that would be required to clear the top of most suppressors.

Would you ever use a suppressor that doesn’t attach to a gun’s barrel?
