@krw62756 It works well for my old ears. Wished I had one 30 yrs ago. Green Tip 5.56 w/suppressor in 16" barrel is a bit quieter than .22 LR sans/suppressor. .308 has a softer bark but not going to ninja anything. My Glock 17 is a hoot suppressed :-) The can is as long as the pistol but when you get passed that, it really is fun. Still wear electronic ear muffs but it is a more pleasant experience. I'm not loading sub-sonic rounds. Worth? If you catch parts on sale and have some patience the cost doesn't hurt so much. Paying for a tax stamp is a bit of government over-reach because of the "ninja" fear from gun-grabbers. To me, it is worth the hassle and cost.
Glock is heavier than the can. Runs well. No hiccups with feeding while using a firm double-hand grip. Plink of steel plates seems louder than the bullet sound.
