    Default Do silencers cause negative effects?

    I have heard from multiple sources that using a silencer on a gun, lowers the speed of the bullet or the range by a few meters.

    I would like to someone more experienced with guns confirm/disconfirm this.

    Suppressors trap, redirect or alter gas expended from a discharged cartridge, both in front of and behind the expended bullet. This will effect your weapon’s operation, and to which extent depends on the weapon and ammunition used, as well as the suppressor’s design. Suppressors cause back pressure, although newer designs cause much less than what they once did. How and when it occurs is critical.

    Pistols suffer the opposite effect. Suppressors lessen the recoil impulse required to make your pistol cycle. Some require recoil boosters to ensure proper operation. Low-powered ammunition can turn your semi-auto into a single shot. Suppressors can be attached to revolvers, but much of the trapped gas just goes out the cylinder gap, lessening efficiency.

    An internal combustion engine can be tuned to run with or without a muffler, so can a firearm. The overall performance differences between a suppressed vs non suppressed firearm is negligible.

    There is a difference in performance, usually not significant, even if more than negligible. That said, if you are tuning a hunting rifle for a

    suppressor, you probably want to run it down at the range, and get used to the performance difference.

    Can't try them on real guns here but I did try one once on my pellet gun and it does slow the pellet down just different propellant

    If you want to run an AR-platform rifle with a suppressor, you should also get an adjustable gas block.

    Yes they make your wallet lighter.

    I saw a video of this on the VSO gun channel on YouTube. An AR with or without a suppressor only had about a 25fps lower velocity on average. Shot to shot could easily vary by twice that much using factory ammo so that 25fps doesn't make much difference.

    Shooting the same ammunition in the same rifle when silenced and when un-silenced will result in changes in the point of impact and size of groups, unless you're extremely lucky

    There's a large number of firearms/calibers/cartridges which can't be very effectively suppressed for the simple reason that the bullets break the sound barrier. Muffling the big poof at the muzzle of the firearm simply will not stop the crack of a supersonic/hypersonic projectile. That unmistakable noise follows the bullet for as far as it is flying while breaking the sound barrier, which is +/- 1,000 feet per second. Depending on altitude.

    The only way to get around this problem is to use lower-power cartridges, which don't propel a bullet that quickly. The bullet doesn't break the sound barrier and create a shock wave, so managing muzzle blast is the suppressor's only job. With low-power cartridges, it's possible to make the sound of shooting a semiauto pistol so quiet that you can actually hear the click-clack of the hammer.

    Using rounds that weak will not appeal to any mass-shooter, and won't be as deadly as a mass-shooter would want.

    So basically, reduction of muzzle blast with a suppressor is a good thing for a law-abiding citizen who wants to preserve their hearing. The notion of mass-killing with a suppressed firearm is utterly bogus. As far as robbing convenience stores, all that's needed is a gun and a threat. The robbery will happen regardless of how loud the gun is.
