02/16: I don't know if this is good or bad.

Is it better to have dumb criminals with access to firearms, or a smart criminal. This is definitely the product of a dumb criminal. From the makers of bad idea jeans!

What we have here is a home made silencer on a little revolver. I suspect it's a 32, but I don't know as I'm not able to identify pistols on sight, it both modified and damaged and I was not allowed to handle it.

The issues, in order of importance to me starting from safety and leading on to effectiveness:
A) modifying a weapons barrel is a great way to induce weakness or blockages unless you know exactly what you are doing ala a gunsmith. These in turn can result in a variety of catastrophic failures starting with barrel rupture and continuing up to the possibility of a round getting stuck in the barrel which means the next round fired will likely cause the firearm to misfire and explode. As this modification was not straight in line with the I don't believe there is in indicator of gunsmith level of workmanship.

B) Silencers or suppressors are specially designed with a series of baffles that the bullet travels through. As it passes through the hole that is precisely milled to match the diameter of the round, each baffle effectively peals of some of the sound, flash and gasses created by the burning gun powder. As this is a home made silencer it is unlikely the baffles it contains (if any) fit the ammunition size closely to be effective. Now if we consider that the silencer is not on perfectly parallel to the barrel... Yeah, no baffle at all I suspect.

C) This is a big one. SILENCERS DO NO WORK ON REVOLVERS. Sorry for shouting, but really dumb criminal, read a book. As mentioned in B) silencers work by containing the sound and gasses the burning gun power creates. The problem with revolvers is that they are not sealed in the firing area nor along the bullet path. Gases and sound can escape around the rear of the drum that holds the bullet in place so the hammer or pin can fire the round. Likewise the front of the drum is another point where gases can escape. So at best in a perfectly filled and mounted suppressor you could only get partial effectiveness. This might be enough to mask the noise from a couple of blocks out of doors or perhaps enough that one could shoot inside a structure with out people outside the structure hearing it. But not on a home brew off angle concoction.


You know what, I'm going to vote in favor of dumb criminals.



BTW if you want to see this little gem for yourself it is in the policeman's memorial room at the Firefighters Hall and Museum in Minneapolis. This is a great little museum run mostly by retired or current firemen in a volunteer basis. There are some fantastic preserved firetrucks, tons of firefighter equipment and great displays. There are mock ups and a fire truck kids can climb on and in the summer there are fire truck rides. Kids seem to love it.
