I don't have any, but I have studied them a bit. Different baffle designs are not the only consideration in effectiveness. Comparing suppressors by saying "X Brand" has K baffles so it must be louder than "Y Brand" that uses the new Z baffles is not always correct.

Size is the major factor, a longer suppressor with one baffle design may be quieter than a shorter one with a different baffle. Is the difference the baffle design or the 3 more baffles in the longer suppressor? Also, pressure and gas volume make a difference. Some modern baffles really work the gases making them divert in all sorts of ways inside the tube. Use the same baffle on a lower pressure round and it may be louder since the gas may not be pressurized enough to flow properly through the baffle.

Overall design factors in as well. Hollywood quiet versus quiet enough may mean the difference between a small compact suppressor that allows you to shoot without hearing protection and a large awkward tube that is dead quiet but not practical. IIRC, there is at least one maker who offers his 10/22 integral in either an 18" or 24" package for this reason. Centerfire locked breech pistols require relatively lightweight cans in order to cycle. "Nielson Devices" can overcome some extra weight up front but in general a pistol suppressor is going to be lighter and smaller than a design for a rifle or subgun, and usually louder because of it.

From what I can gather, the monolithic cores are a manufacturing/assembly cost saving measure. They can be made on a CNC in one process instead of individual baffles that have to be put in and taken out one at a time, stacked in the tube, timed if necessary, etc. Don't think they are any quieter than the same baffle design made as individuals.

There are dozens of baffle designs. Check out [Only registered and activated users can see links. ] they have a gallery of disassembled suppressors. However, most of the newer ones are welded shut so it's hard to find pics of internals. The US Patent Office online lets you view silencer patents though. Silencertests also have measured sound level tests, although those can be misleading. Everyone hears sound differently, so even though a suppressor may have a higher DB output the tone may be such that most people think it's quieter than a lower DB one. Most people recommend you visit a dealer with several in stock and do a side by side comparison test on the type of firearm you plan to use it on.

yah the round and pressures make alot of difference . i have checked silencer talk out really good forum alot of machinist on there . they have 3D model pics of some of the internals which is really nice . i have made a few models in solidworks from some of the pics and designs ive seen on there mainly mono cores and a few K baffle cores and then put them through a flow analysis and they came out pretty good for the flow disruption . did some fat cans too 3.5 dia about 5 inches long . most of em are 2 inch and about 7 inches long

but are there really a Z baffle design out there ??? ive seen the Y design alot they have been around for awhile almost as long as the flat washer type . and they work pretty good from what i hear . the old M16 style silencer has a big expansion chamber with three to five cone type baffles . then you have the cobra can that has a spiral core used on the mac 10s

Z-Jet baffles:
[Only registered and activated users can see links. ]


Back when I worked for a gunsmith there were a lot of NFA owners who brought their toys over for show and tell. The quiet ones were always the larger cans, but modern advances seem to have let them shrink them down a bit and keep the same performance. About the tops for quiet was a co-axial design on a MAC11 subgun. About a foot long, 2" diameter outer over an 1 1/4" inner tube with standard M baffles stacked inside according to the owner. Sounded like a Singer Sewing Machine at max speed when fired, you heard the bolt clacking back and forth and that was about it.

SSupressors have come a long way. Now they study gas pulses and reflect them on them selves, timing it to cancel out noise...

I always figured the ultimate would be an "active" electronic suppressor. You know some high end cars have noise cancelling built into the sound system. If you look at a sound as a waveform on an oscilliscope and inject an identical noise into the area with it being 180 degrees out of phase they cancel each other out. Wouldn't even have to be attached to the gun, you could wear a "boom box" and have it cancel out all the sound in the room.

so they used the organ pipe theory ??? thats what it sounds like to me but most people i talk to they use that more for performance exhausts

HAHA CAN YOU SAY DRIVE BY THEY ALWAYS LIKE TO TURN THEIR MUSIC UP TO TRY TO MASK IT BUT IT DOESN'T REALLY WORK . YOU NEED THE SOUND WAVES TO RETURN AND DISRUPT THE PERCUSSION WAVE OF THE BLAST RIGHT ???

I'm on the cusp of Purchasing an SWR Spectre from guns and ammo whse in Manassas Va (that is, if I dont blow it all on a 9mm pistol this weekend at the gunshow).
Been doing alot of research on this company and they come HIGHLY recommended.
This particular suppressor is all stainless (as opposed to alum) and will fit my .17 and my .22
