TFBTV Mythbusting: Silenced SIG MPX

In the comments to James’ recent video review of the SIG MPX (click here to see it), he noticed that a number of TFB viewers said the MPX was filthier than daytime television when you shot it suppressed. Given that so many TFBTV commenters claimed that a silenced MPX would gas out anyone behind the stock, James hung an AAC Evo-9 off the MPX’s muzzle to test this myth. In this episode, James discovers: “Is the silenced MPX more Billy Ray or more Miley?” Check today’s TFBTV to find out.

    So it isn’t really a MP-Ron Jeremy…

  • KestrelBike

    Alright this video was hilarious. Well done. hahaha cheers!

  • Pete – TFB Writer

    No way in hell you ate at BK.

    Hilarious video.

    • James R.

      TWO FOR $5 CHICKEN BURGERS *PETE* (no mayo). Me and Ms. Wanda, the manager at the BK by my house, are on a first name basis. She looks just like the “Ain’t nobody got time for that” lady. She may be, for all I know.

      lol, glad you liked the video.

      • Pete – TFB Writer

        Hahaha.

        Btw. Grilled chicken no buns =/= eating at BK.

        Well done. You have good taste in guns. Food? Ehh…

  • Vhyrus

    You look like a retarded klan member with that napkin on.

    Tried posting a video link of another reviewer (whom this site frequently links) with an experience counter to the articles, in an attempt to show where this idea comes from and that indeed people do have this issue given their setup. But it didn’t pass the moderators scruitiny, god forbid an actual discussion of differing viewspoints takes place. If that mod wants to email me his reasoning, please feel free to.

    Stay classy TFB

      There isn’t a person sitting there checking every comment, it’s a bot that catches links and prevents them from being posted because it’s spam half of the time. Any link. I don’t control it, I can’t release comments, and I can’t even post links myself. No one is persecuting you, big guy. Relax.

      • Austin

        Wait, there isn’t a staff exemption on that rule?

        • James R.

          Could be, but I always post from my personal Disqus account and have never even tried to get a staff account, if such a thing exists.

          • Austin

            By staff I ment those with permission to post articles and/or videos

          • The staff has permission to write post but nothing is usually live until I proof and edit them. I also do some scheduling of the post.

          • It does exist but there are only two of us myself and Steve.

        • No check below—-just two of us release Disqus held comments.

    • Joseph Goins

      I think we all know the other “reviewer (whom this site frequently links) with an experience counter to the articles” is Tim from Military Arms Channel. It doesn’t mean that either person is right or wrong but merely that each reviewer felt a perceived difference in debris and gas. This can result from each reviewer’s personal tolerances to different ammunition to different suppressors. It really doesn’t “bust” any myths like the title of the article claims.

    • FarmerB

      Huh? I see a link to a video from you at bottom of this page. The way most moderation systems work is that a bot flags ’em (links are always a suspicion of spam) and a human gets to review and release them. Therefore it might take a few hours to get released – as it seems in this case.

      • That is in fact the case. I can’t park on disqus so it may take a couple of hours between checks if I’m busy with other things.

    • John how about you tell me what you’re talking about I haven’t deleted any comments from this post and I’m the one who does it.

      • John

        My mistake, an hour after my original comment, it went from awaiting mod approval to just disappearing, and I assumed the worst not knowing how the system works. My apologizes for the whinny outburst.

  • plingr2

    And left-handed shooters?

    • Austin

      The potential for brass hitting us in the face is the bigger concern

    • Southpaw89

      Was thinking the same thing.

  • Harry’s Holsters

    That’s a sexy gun. Shot a Scorpion a couple weeks ago but didn’t like the safety. This gun OTB with all the features has my wallet shaking!

    • Malthrak

      The safety on the scorpion can be swapped and changed very easily and there’s already a number of options out there for it. If that’s all that was bothering you, spend the extra $20 and save yourself $400 over the MPX. Not that the MPX is bad, but if the safety was the deciding factor…there are options.

      • Harry’s Holsters

        The one I shot I had an after market safety. If I didn’t shoot ARs so much I could live with the scorpion and will still probably pick one up but it’ll never be a go to.

  • toms

    In all fairness it looks like the wind was blowing 20mph in the video and 147gr is the least gassy of all ammo. I shot a suppressed MCX pistol and it had blowback but so does almost every gun I shoot suppressed. Id say it was on the more gassy side of manageable but not totally obnoxious like a few guns I’ve shot.

    • Joseph Goins

      I think you should put on your big boy underwear and get over it. It happens.

      • Ethan

        Until someone designs a gun where it doesn’t happen, that is.

    • Steve

      I just cannot imagine a 9x19mm being gassy enough to bother me. The only gun I’ve ever fired suppressed where I was like “nope… I’m done” after one shot was the M14… the open action made it absolutely punishing with anything short of sealing safety glasses.

  • Treyh007

    What a bunch of puss’s……. If u can’t take the slight blow back then u have no right shooting such a bad ass weapon system. Go buy a Hipoint carbine and put a oil filter on it, that might be a better fit! Great Vid James, keep’em coming! 👍🏻👍🏻

  • Joseph Goins

    Before I begin my comment, I want to say that I do not know Tim from Military Arms Channel. I don’t believe he lies in his reviews, I don’t believe he makes things up, and I don’t think anyone is paying him off. (He was the first person I can think of to call the Remington R51 a spade for crying out loud.) Don’t consider this an attack on him because it is certainly not.

    One of the comments in the TFBTV video referenced how Tim said shooting the Sig MPX suppressed caused a lot of debris to come back at the shooter (see first link). I do not own the gun and thus cannot comment on the gun. However, I believe that Tim has become very elitist over the last few years and is not reviewing guns for the Average Joe anymore. He almost said as much in his “Ultimate SCAR” video by saying that he spends his money on “the finer things in life” (see second link). Power to him; I wish I could spend over $15K/year on guns and accessories.

    When he does his reviews, he is doing them from the viewpoint of personal enjoyment while shooting. This doesn’t translate well to people who simply want a good gun for 1) self defense, 2) general shooting, 3) preparedness. The debris he mentioned (notice: I am not saying he lied) would barely be noticeable in a situation where you need to shoot in order to save your life. I feel that anyone reviewing guns should not do it with a range mindset. People should become more mentally resilient with their firearms and take reviews with a grain of salt.

    (I could make the same comment about someone like Nutnfancy with his size and weight constrictions particularly from his “Dude, You Got Too Much Crap on Your AR-15” videos. He means well, but he could simply man-up and get more physically fit instead of complaining about an accessorized gun weighing eight pounds.)

    • Austin

      I think you are on the right about him getting a bit elietest but that’s why you have to take into account the angle that the reviewer comes from. Nutn for example is primarily about real world use and a bit of the prepped mentality whereas Military Arms Channel focuses more on guns and accessories that could feasibly be used by militaries.

      • Joseph Goins

        I think Tim dropped the “military” from Military Arms Channel a while back. It should be renamed “Guns and Gear No One Can Really Afford.”

        • Austin

          To a degree but the long guns at least the have a potential relation to military use or military tech development

    • Malthrak

      One will notice however than when MAC was comparing the MPX and Scorpjon, MAC went with the dramatically cheaper and far less “elitist” Scorpion, based on both price and gas blowback.

      • Joseph Goins

        I never equated “elitist” with “expensive.” I said that a perceived attitude of elitism has moved his mindset away from reality towards comfort/enjoyment and fanciness when doing reviews to the point that they aren’t reviews made for the Average Joe focused on self-defense and other non-flat range activities.

        • Malthrak

          Fair enough.

  • thedonn007

    If the MPX was a side charger (with the ability to change to left or right hand) I would have more seriously considered buying one. It is a shame they went with the T-handle. I ended up going the 9 mm AR-15 route. I will eventually get a side charging upper for it as well.

  • “Science Mask” for the win.

    • Pete – TFB Writer

      I’m making targets from MCD wrappers to try and keep up.

  • Just my two cents worth but I’ve shot the select fire version a good deal in full auto and I can’t say I ever noticed any blowback or crud hitting my face. Different suppressors may have something to do with it.

    • Joseph Goins

      Suppressors, ammunition, wind conditions, and user sensitivity will always result in different subjective test results.

  • Pete – TFB Writer

    So much fun. Especially suppressed.

  • Ethan

    PROS:
    -Combat effective at all defensive ranges (<200yds)
    -CHEAP to feed ($0.19 per round vs 5.56 $0.33 per round)
    -EASY to shoot
    -Great selection of quality ammo,
    -Smaller, lighter, faster, etc than most AR's.
    -Suppresses about as quiet/effective as super-secret-ninja 300BLK ARs, without costing $1.25 per round.
    -No buffer tube = extremely compact transport / concealment (if you're into that)
    -OMG IZ NOT AN AR-15!!

    CONS:
    -Not as much terminal energy as a 16" 5.56 AR, or 8" 300BLK SBR
    -Not as useful past 200 yards (if that's your thing)

    What's not to love?

    • Joseph Goins

      I think you and I have different definitions of “combat effective at all defensive ranges.”

  • Malthrak

    Can you guys put that sucker on a scale next to a similarly configured CZ Scorpion (e.g. either both with stocks or both without)?

  • jp2336

    Looks way better than what the MP5SD does! Maybe I’m just just a puss, but damnnit does the SD vent right into my pupils.

  • Dual sport

    Every gun and nearly every round are a thing unto themselves. (Is that proper English?)

    Two guns that came off the same line can be entirely different in many ways. Adding a suppressor introduces another element to this. That is why we sight in every single gun and are supposed to pattern every single shotgun.

  • Jon Hammett

    Why did sig make this gun piston operated?I have been looking for a reason, but I can’t find any of someone could she done might for me that would be great I can’t think of a reason to not stick with it being a straight blowback design, so it makes me curious
