I just got a chance to shoot one of these pistols over the weekend. I was impressed that it could shoot .22 High velocity rounds as well and subsonic. I have no device to measure sound but the HV rounds were quiter than the subsonics. Anyone have any info on what kind of technology they use to design that type of suppression? ie how they eliminated the sonic crack or at least made it quite. There were no wipes in the supressor. I could not get a good enough look at the internals to see what type of cones or baffles were used.
Thanks in advance.

The newer "Amphibian" has a ported (2 ports IIRC) barrel that is approx 1.75" long, the rest is the baffle stack and, it's designed to be used with hyper-sonic ammo. The ports bleed off gas and slow the bullet to subsonic velocities.

If you want a good look at the internals and baffle design of an AWC can, you'll probably have to buy one and cut it open yourself.

FWIW my husband and I have six of their cans between us (Thundertrap * 2, Spectrum, Amphibian, Abraxus, and Nexus) and there's not a bad one in the bunch.
