Sounds bogus, to me. I had an early superblackhawk 44 mag. The
cyl-to-barrel gap was a tight 0.003". I can't see any production
process permiting a tighter tolerance. Anyway, that 3 mils didn't
prevent a wall of flame and a deafening boom from escaping the gap.

And now, even an AK 47 said to be no-achievable because of the "gas
block"....

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****.


Mostly right. Much of the noise in a shot is the crack from the bullet's
sonic boom. Using sub-sonic ammunition eliminates that sound.

Suppression of the sound of the explosion that propels the bullet is the
domain of the silencer. A suppressor is worthless on a revolver and the bolt
will begin opening - allowing sound out - on an automatic before the rest of
the sound can reach the suppressor. Where a suppressor is most effective is
on a closed-bolt rifle.

My state, Texas, just allowed hunting with a suppressor, effective September
1st.

Whether you build your own suppressor (usually pretty easy) or buy a
commercial one, the BATF requires a $200 tax for each one.



The BATF agents will show up with machine guns and kill you if you don't
pay the $200.00 tax. Ask the Branch Davidians who survived. ^_^
