Yankee Hill Machine Sidewinder Suppressor


Yankee Hill Machine (YHM) introduced a new pistol sound suppressor at the 2015 SHOT Show called the Sidewinder. Available in 9mm, .40 S&W and .45 ACP, the suppressors attenuate the gunshot by 31.5 – 36 dB depending on caliber according to the YHM staff.

These pistol suppressors are user servicable for cleaning. Once mounted, the Sidewinder can be indexed to correct for bullet movement. The indexing process is very simple: the shooter pulls out on the suppressor and rotates it.

Yankee Hill includes a heat resistant pouch with the suppressor. The pouch can withstand heats to 2500ยบ F and can double as a mitt to remove the suppressor from the gun.

The company anticipates shipping in the second quarter. The MSRP is $699.

    I keep asking this question .70 years ago hi stardard ,welrod , delisle ,guns sounded 70db -80db .70 years later the best are 120db .40db LOUDER . WHY CAN’T WE MAKE GUNS AT 70-80DB .with modern materials etc why are guns produced today LOUDER than WW2 guns .Shirley we are technically more advanced engineering can/ should produce better guns than 70years ago.!! 70db -80db pistols and rifles where are they?

      I’m no suppressor expert, but as I understand it one of the biggest reasons is that the WWII designs used a wipe system, with rubber wipes coming in contact with the bullet as it passed through the suppressor. This allowed the suppressor a much better seal, but had significant negative effects on accuracy, and wore out quite quickly. Wearing out quickly is a pretty big problem for civilian suppressors what with the 1934 NFA complicating the process of getting replacement parts.

      And don’t call me Shirley.

      It’s amazing no one has answered such an easy question. First of all, they use wipes. These have a certain round count, then they are disposed of (welrod) or have to be reinstalled. Second, none of the guns you listed are semi-automatic. Look up 300 Blackout bolt rifles and see how quiet they can get when suppressed. If the action is going to open, you’re going to have some noise. That’s all there is to it. Also, there is ZERO market for a Welrod pistol anymore. If they have wipes, it has to be sent back to the factory after 200 rounds.

        >If they have wipes, it has to be sent back to the factory after 200 rounds.
        No, they don’t. The ATF doesn’t considered wipes to be suppressor parts so they are user serviceable, and there are still suppressors in the US that use wipes such as the Thompson Machine Poseidon.

    Certain parties often complain that guns are not subjected to the same consumer-product safety standards as everything else bought and sold in the United States (even toy guns).
    Let’s go there.
    How long would the CSPC let guns be sold for youth and sporting purposes with the unsuppressed noise levels they generate?
    What other consumer product is allowed to expose users to noise levels exceeding that of a JACKHAMMER(!!!) when a cheap and readily-available noise-mitigator is available?
    How would any product that generates the noise levels of a twelve-gauge shotgun, a .45 cal. handgun, or a .308 rifle not be deemed “defective” if it omitted a readily-available noise-reduction device?

      I’m sorry, your complaint has fallen upon deaf ears and could not be registered at this time. Please try again later, thank you.
