OT * Are gun silencers on pistols really as effective as they show in

I would appear not. *Look at these tests:

....and here is a chart listing real world sound levels.

I can do a very loud fingers-under-tongue whistle that hurts most
people's ears, they typically reacting by covering their ears with
their hands, abeit too late. *I've measured my whistle at 113 db. *The
above chart tends to indicate that most suppressors reduce a gun's
report only to close-to-painful.

So, it would appear those movies where the silencer (suppressor is the
PC term) merely goes "pffft" are nonsense. *OTOH, these are jes
commercial silencers, not very expensive ultra hi-tech military
suppressors. *Also, there is sub-sonic ammunition, which will go a
long way toward reducing heard noise. *I once watched a marine in full
range competition regalia shoot a precision .22 target rifle
(un-suppressed) using sub-sonic target ammo. *It didn't make much more
noise than those silenced firearms one sees in the movies.

BTW, if you see a suppressor on the end of a revolver, you know it's
total bull****. *

Harbor Freight often carries an inexpensive Sound Meter for $14.95 and
it works as well as the 'scientific' versions costing $100's

A bit educational to use.
