Hey guys, I bought my Eco-9 in the early warning days of 41P back in early 2014. Just recently acquired my glock 19 host and threaded barrel, loaded it up with 135 grain ammo (advertised as 1010 fps) and took it to my indoor range.
While shooting suppressed, I got a chance to take off my ear pro and see how it really sounded. It did help quite a bit, but I still got some tingly feelings in my ears, telling me it is probably not hearing safe, so I only shot a few rounds like this. I shot 1 round of 115 grain for comparison to make sure my 135 gr. were really subsonic, and there was a good difference. Am I correct to say that this combination is not hearing safe? Maybe hearing safe outdoors? Just kind of disappointed, because I wanted to be able to shoot subsonic 9mm without earpro. If I can't, there isn't much point other than to save my ears in a HD shooting (no fun range time). I will try a heavier buffer spring in my Glock, and hope that that helps. |

How quiet your weapon will sound is dependent on many variables. What is around you makes a big difference. Shooting in a metal box with rounds impacting metal is loud |

Shooting in a metal box with rounds impacting metal is loud I don't think the backstops at this range were metal, but definitely the sound waves reverberating inside the building increases the time your ears are subjected to the sound. I'll have some time to shoot outdoors around Christmas time and I can see how it sounds then. Are the newer cans (Eco 9, trident, etc) that much better at sound suppression than my older can? |

Indoor ranges are really bad for your ears. they just make everything so much louder. Keep in mind that even if you shoot it outside and it doesn't hurt it doesn't mean that its hearing safe. But from my experience most subsonic rounds are easy to tolerate with a can on the firearm without hearing protection.
I would recommend still wearing ear pro. |

You had unrealistic expectations for what the silencer is going to do. If you shoot outdoors, and you handload some 9mm to be as quiet as possible, you may be able to accomplish what you're looking for. It still isn't a great idea. Gunshots are loud, even suppressed. There's this myth that below a certain dB level, you're not doing hearing damage. As everyone in this thread has pointed out, even if it was comfortable to shoot without hearing protection, that still doesn't make it 100% hearing safe. A very nice thing about shooting with a suppressor is that you don't have to double-up on hearing protection, or you can wear much more low profile earmuffs. |

My 300 blk with subs is pretty darn quiet, and I was expecting similar results with subsonic 9mm and an 8.5" can.
However I never shot my 300 blk inside either. Has anyone shot subs in 9mm and 300 BLK on the same day/similar conditions and have a much different result between the two? I guess a DI style rifle would be a little quieter than a blowback due to the time of the chamber opening (pistol chamber opens immediately, DI opens after gas makes it back to BCG). |

I would never willingly do a range session of centerfire weapons without earpro, probably not even .22lr. Hunting and HD are totally different ballgames. YMMV Your 22LR silencers must really suck! 
As for the Eco-9 silencer, its a 1.25OD suppressor and probably not up to todays standards. They were made with out of spec parts in order not to waste a large bad batch they had a lot of money in. Shooting indoors is never a good idea, even with a quality suppressor if you are expecting quiet. Shoot outdoors, with quality factory subsonic 147 grain ammo, and if you are not pleased, pour water into the back of the suppressor before shooting. Hearing safe is a industry term that is over used and seldom properly understood. Hearing loss is dose related. |

After a mag dump from a 1911 in the back of a moving honda accord w/o ear pro, my ears are a tad sensitive. Not that I'm being defensive but I'm not sure a spectre II sucks 
I'd like to protect my hearing as much as possible - when it's gone, it ain't coming back. I'm not interested in earning the "too bad ass for ear pro" merit badge. YMMV
