Sintercore’s Improvement to “Perfection” & Other Polymer Handguns: The Deadfall

When the VP9 was originally released to the market, I distinctly remember the dominant part of the conversation (aside from its an HK, therefore it must be good and pricey) being the inclusion of the extra slide-racking wings on the rear of the slide. Certainly unusual looking, the choice was polarizing for the new pistol which after reviews and handguns started matriculating to the market and the choice went from weird to generally well-liked.

Seeing similar room for improvement for many other polymer, striker-fired handguns, is Sintercore. The Deadfall is a similar system that takes advantage of the polymer rear slide covers to add those wings to the handgun. While not a full extension system suitable for belt or pocket-racking, the Deadfall is ideal for those wanting to eek out some additional usability from their existing handgun without the use of adhesives or re-milling the slide.

The Deadfall is being introduced for the common 9mm, .40, and .357 Sig Glock models with planned expansion to the Glock 43, .45/10mm Glocks, Smith & Wesson M&Ps, Springfield Armory XDs, XDMs, and XDS handguns. Sintercore estimates June shipment to the other platforms.

Pricing is set at $19.98 for the Glock 9mm and all other platforms. Customers wanting custom plates can opt for uploading their own files.

Details (from Sintercore):

  • This product is designed to provide extra traction, similar to grip tape, with a better look and without the downsides inherent with adhesives or super-wide slide rackers; this product is not designed for racking the slide off your belt or pocket, as nearly all factory rear sights provide that functionality

  • A discounted pre-order offer is available for Glock® 43, Glock® .45 / 10mm, S&W M&P® and Shield™, Springfield Armory® XD/XDM® and XDS® with estimated shipping JUNE 2017, and we will send timely updates regarding production
  • Weight: 2 grams, or approximately the same as a standard slide plate due to the carbon fiber construction
  • Width: Varies with pistol model, but approximately 5/64″ added to each side of the slide
  • Holster compatibility: This product should not affect holster compatibility and works perfectly with Safariland® SLS and Blackhawk!® Epoch™ holsters that incorporate hoods, though we recommend you evaluate the potential for holster fitment issues before ordering

    eke out*

      It never fails, the first comment on almost all articles now is someone pointing out a typographical or grammatical error.
      TFB should start paying us for doing some of their editing work

      • derpasauras

        Maybe if they got rid of the people who write like Nicolas C then this wouldn’t happen.

      • 22winmag

        That would be PROOFREADING not EDITING.

        Those two things are not the same.

      • Greg Anderson

        I’m not mad. If someone has only ever heard the term, ‘eek out’ is a perfectly reasonable error.

  • DanGoodShot

    Ok..soooo grammererer nazis aside, I have and love my not so expensive VP9. I absolutely love the little wings on the back. I also have an S&W Sheild that I think those little wings would be fantastic on. I’m still relatively young, I don’t have arthritis but it is a nice feature none the less. Why wait to get arthritis when you can prevent arthritis!

    • Neal – Sintercore owner

      That was exactly my thinking. They’re a nice feature to have on a carry pistol, and there don’t seem to be any downsides. Hope to see a Deadfall on your Shield. 🙂

      • DanGoodShot

        Oh, they will be. You can count on that.
        Edit: I’d be happy to send ya some pics for promo purposes for a small trade of.. oh… idk… some of them there turn ta powder compressed .308 boolets. 😉

        • DanGoodShot

          Kiddin’ on that. But I do know quite a few old-timers at the range who have a lot of the polymer guns that wish they had these things on theirs. Once they see em’ on my Smith they will want! I’ll be sending em’ to your website. 5 of them bought VP9s after they shot mine. Just because of the little plastic ears.

          • Neal – Sintercore owner

            Crazy! That would explain why so many people are buying this. Haha.

            I appreciate that info and the offers.

          • DanGoodShot

            Edit: Hey, old folk are a great market thats often way over looked! The old Coots I know figure they can’t take it to the Grave with em’!
            I just got done on paypal. Ha! Lookin’ forward to trying them out.
            So, yeah, it’s ok if a few of those boolets accidently fall into a box that happens to be going to Oxford CT for a s&w sheild. 😉
            Don’t mind me, All us submariners are a little touched.

    FYI: I’m no longer taking custom engraving orders (except for 10+ product orders) at this time due to high order volumes and limited time.

    Happy to answer any questions people have about this product. You can also contact Sintercore via email, phone, Facebook, Reddit (u/sintercore).

    • Jared Vynn

      Any plans for other handguns like the Ruger LC9S?

      • Neal – Sintercore owner

        That’s one of my main carry guns (along with a Glock 19). I just added it to the preorder list for June release. Thanks for the suggestion.

    • Greg Anderson

      Damn, now where will I get my IIIIII% moldy labia spartan hat glock attachments?

    • nova3930

      Any chance we’ll see one for the SIG 320?

      • Neal – Sintercore owner

        Possibly. I need to get my hands on the slide end plate.

        • nova3930

          Can’t speak for anyone else but I’m in for several if you do.

  • USMC03Vet

    Will this work with models that show cocked striker that protrudes through the back plate?

    • Neal – Sintercore owner

      Yep. There’s a circular hole that allows the indicator to protrude into the Deadfall. The actual viewport design on the very rear of the Deadfall is not set in stone yet (as in, the viewport could be shaped any way I want it, since it’s just a window). Since the XD models are on pre-order, I’ll have time to send out concept pictures to customers who pre-ordered and let the hive mind decide on the exact look.

      Howdy from a fellow 03.

    I literally just received one of these in the mail today and installed it a few minutes ago on a Glock 22. It works. I think it looks fine. If anything I’d prefer it to stick out a bit more, but there’s enough there to definitely make it easier to rack the slide. It’s somewhat less than the VP9 ears but I know they’re trying to keep it really low profile to keep from interfering with holsters and stuff. The company sent like… an almost annoying amount of email status messages. I know lots of people get all bent out of shape if they don’t get orders immediately or know what’s going on so I guess that’s probably a pro for most people. I kinda like ordering stuff and forgetting about it and it being like Christmas morning when a package shows up on my door.

    • GnarlyNardHair

      Forgot to mention that I’m gonna put in a preorder for another one for a 10mm Glock because I like it.

      • Neal – Sintercore owner

        Hey, thanks for the feedback. Very glad you’re happy with the Deadfall wings so far. After you’ve used it for awhile, it would be really great to read your long-term review (there’s a section on the website where you can submit it).

        Sorry about the multiple update messages. In previous pre-orders, I had a ton of customers asking every day when stuff would be ready, so now I just go above and beyond to ensure people are kept in the loop. I can see how that could get annoying. I’ll try to find a happy medium.

        • Gary Kirk

          Yet again, I find a company willing to respond to Joe blow.. Was almost getting ready to dismiss y’all as another gimmick product.. But you apparently take pride in what you do. So, will not dismiss y’all, and may look into your products now.. I personally appreciate the attention to the consumer, even though I am not currently one of yours, I may become one in the future..

          • Neal – Sintercore owner

            My pleasure, sir. I do my best and follow the golden rule.
