Got another local shop who wants to carry my cans, and after a few months of use & abuse, I've decided to make a couple of revisions. Where the Phoenix is concerned, it's a change in the booster & rear cap design, as well as baffle alignment system. If any of you remember gen I, it had alignment tabs on each baffle, and the piston retention system was similar to that of the SiCo Osprey, with 3 blind holes in the cap and 3 tabs that rode in notches on the piston. In demonstrations, concerns arose over the rear cap unscrewing from the can and remaining on the gun, which was never actually a problem in use, but people were worried about it nonetheless. So I revisited that, and came up with a rear cap that can be removed and installed by hand, or by using the same wrench as the front cap if it became too tight. The new design engages the piston tabs inside the booster housing rather than using pins on the rear, which simplifies my pistons in eliminating the 3 grooves. As before, my 3 lug pistons are proprietery, but my booster can use 10 point SilencerCo/Rugged/etc pistons. The rear cap is now 7075 Aluminum, Type II anodized black. The remainder of the suppressor construction is the same with Ti housing, 17-4 booster housing, blast baffle & front cap, black anodized 7075-T651 baffles for #2 thru #8. Baffle alignment is now with a Delrin rod that has a key for the clips. Flip the alignment rod around for a stepped acetyl piece that is used to push out dirty baffles for cleaning. The baffle change does simplify production a little, but the real reason was that people checking it out who didn't bother to read the instructions tried to drop the baffles in rather than stack them and slide the can over the stack. This resulted in the thin tabs sometimes finding their way over the baffle skirts and then becoming stuck when people tried to shove them in. Other than the rear cap, it still looks the same, but the revisions netted a 1 ounce weight loss; the Phoenix XLV now weighs 10.1 ounces including the piston & spring. Length is still 7", and I have finally been able to meter it: 131.9 dB avg. with no discernable FRP. For comparison, the SiCo Osprey 45 is 8" long, weighs 10.9 ounces w/piston and meters 131.3 dB but with a 134 dB FRP. The Octane 45 is 8.5" long, 12.1 ounces and meters 132.0 dB. Rugged Obsidian full configuration is 8.6" long, 12.8 ounces and allegedly meters 129.3 dB. The "toughness" of my Phoenix lands between the Osprey and the Obsidian; with the round Ti housing, the Phoenix can handle more than the Osprey and is .357 mag/10mmm and full auto rated, but not designed for continuous use on submachine guns with their high rates of fire like the "belt fed rated" Obsidian.
