Part Two SIG Sauer Suppressors—–SCIENCE MATTERS

unnamed

SIG Sauer is determined to market the best suppressors money can buy. You may say well that sure is a confident statement. I guess it is but when the team leader, Kevin Brittingham, the former owner of AAC is running the show you can afford to be confident in your team. The man knows what he’s doing!

This is the second installment in the SIG series Science Matters. Rather than repeating all of the details let me just give you a link to the website SIG has put together. Link Science Matters

From the SIG web page:

The silent era has begun. Based on its unmatched understanding of sound and the end user’s requirements, SIG SAUER® is engineering cutting-edge signature reduction solutions. Grounded in hard science, not marketing spin, these advancements are helping military forces triumph on the battlefield, while transforming the shooting experience of citizens.

    While it’s great to see a company pushing the science aspect of suppressor design and use IF they are measuring DB reduction using a meter while standing at the shooter as seen at 2:50 in their video that is not to industry standards.

    The correct placement for measuring DB reduction is 10 feet from the muzzle perpendicular to bullet flight path.

    If that is measuring something else then they should indicate that.

    • Giolli Joker

      Some suppliers give the standard measurement and the “shooter’s ear” value, I suppose they were just testing for the second, in that part of the video.

      This is a marketing video… not a paper supposed to be peer reviwed.

      • claymore

        So you can still market and be correct while doing it.

        • avconsumer2

          Indeed. Why even give experts a doubt?

      • Cymond

        For me, seeing marketing that uses non-standard measurements makes me distrust their claims.

    • TCBA_Joe

      Sig measures multiple locations when sound testing.

    • Dave D

      Claymore you are correct on the “standard” measurements. However, there are also DB ratings at the shooter’s ear. That is what you are seeing and the numbers can be very interesting and can help when picking between two cans. Silencershop has been pushing these numbers and can be seen in their YouTube videos at the end when they show the overall numbers. I really like seeing the at the ear ratings and make some cans look more attractive after looking at the 10 foot measurement.

      • claymore

        At the ear measurements are just a marketing tool. They don’t matter in the real world where the sound at the shooter means nothing. A better measurement would be down range where the potential targets or enemy are because it matters one hell of a lot more what they will hear. Measuring at the shooter just gives the buyer of the product a warm fuzzy feeling they he can hear what his purchase is doing.
        Or even better, what suppressors were originally designed for, is to measure the ease of locating the source of the report that is what is really important to a user actually using them on human targets.

        • Dave D

          Please understand that other users do not share your emphasis that the primary measurement should be downrange or even at the standardized feet away from the can. My personal use of a silencer is to better enable communication with those around me. We don’t always for the luxury of wearing our Peltors and usually others around me do not have access to Peltors. The silencer greatly assists in communications and a measurement at the shooter’s ear is meaningful for this purpose. My secondary use of the silencer is to help lessen my long term hearing loss. While down range measurements can be beneficial in some cases, it is not my primary reason for using a silencer.
          I agree with you that there is far too much misinformation used in silencer marketing and the numbers are so murky the many times the numbers become meaningless. Even the “at ear” measurements have problems in that there isn’t a standard measurement distance that I am aware of. However, I do believe that the numbers can provide some limited insight as to performance that the shooter can expect. Even then these numbers are not gospel. As always these numbers only provide data as to the readings that day with that firearm, ammunition and that particular meter (don’t get me started on equipment issues). Entirely different numbers could occur with the same setup on another day with different atmospheric conditions. This only demonstrates that you can’t simply look at one set of numbers and need to educate yourself with as much information as possible and critically look at the source. In the end, the best test is field testing for your particular situation.

    AAC…wow, there’s a name I haven’t heard since…well, since they ran Kevin Brittingham off…

    • Joe

      Probably for good reason, every AAC can I’ve ever bought has been completely screwed up out of the box. They are great cans when they work just remember when you buy one just factor in the shipping cost of sending it back to AAC to fix their ‘new’ can.

    • Gregory Markle

      Ex-AAC employee John Hollister was doing their presentations at SHOT in January also…I think between the two of them they got most of the brains AAC had and ditched all the egotistical “lifestyle” merchants.

  • JumpIf NotZero

    All for not I’m afraid. They are currently shipping only two cans in their entire line. The 762-QD and the 22lr from everything they announced since well before SHOT in Jan.

    Maybe by next year they’ll get around to shipping everything else. So…. JUST LIKE AAC 😉

  • uisconfruzed

    Very nice & priced right.
    I’ll still glad I got he TBAC Ultras, the Ultra-9 is five oz lighter & had a taper type mount that Sig now uses.

    • Remember that TBAC are more $$ about $1000-$1200 with a QD. SIG’s are about $600-$700.

      • uisconfruzed

        That’s one of the first things I mentioned. Plus I’ve already paid for the two, I need to shore up my decision. 🙂
