Sintercore Deadfall Slide Charging Wing – Install and Review
If you'd rather watch the full installation and shooting impressions, you can watch the video here:
In this post, I’m taking a look at the Deadfall Slide Charging Wing by Sintercore. This is a small add-on that replaces the factory back plate on a Glock slide and adds a small shelf at the rear of the slide to give you more purchase when racking it.
The idea behind it is simple: if your hands are wet, sweaty, bloody, or slippery for any reason, the Deadfall gives you an extra surface to grab onto when manipulating the slide.
What is the Deadfall?
The Deadfall replaces the rear slide back plate on a Glock.
It adds a small ledge at the back of the slide that gives your hand something to catch on, especially near the heel of your palm and fingers. It’s designed to help with slide manipulation under less-than-ideal conditions.
According to Sintercore, the Deadfall is made from carbon fiber and weighs approximately 2 grams, which is roughly the same weight as a factory Glock back plate.
Installation Process
Installation is very straightforward, but if you’ve never removed a Glock back plate before, there’s one important thing to be aware of.
There is a small internal plunger that is under spring tension. If you’re not holding it in place, it can launch out when you remove the back plate.
To install the Deadfall:
-
Make sure the firearm is unloaded
-
Remove the slide from the frame
-
Carefully depress the internal plunger while sliding the factory back plate down
-
Keep pressure on the plunger to prevent it from popping out
-
Slide the Deadfall plate into place
-
Depress the plunger again and slide the Deadfall fully upward until seated
Once installed, that’s it. There’s no fitting required, and everything locks in just like the factory plate.
Test Setup
For testing, I installed the Deadfall on my Glock 23, which is currently set up with:
- Lone Wolf 9mm conversion threaded barrel
- SilencerCo Osprey 45 suppressor
- Mixed ammunition (FMJ and defensive loads)
I wanted to see how the Deadfall performed both dry and with wet hands, since that’s where this kind of product is supposed to shine.
Shooting and Handling Impressions
With dry hands, I honestly don’t need the Deadfall. The Glock slide is easy enough to rack under normal conditions.
Where the Deadfall really helps is when your hands are wet.
After wetting my support hand, the slide became noticeably more slippery. While I could still rack it without the Deadfall, the added shelf made it significantly easier to grab the rear of the slide and get solid purchase.
The difference was more noticeable than I expected. That small ledge gives you a consistent reference point and something solid to hook your hand against.
Practical Use Case
This is not something most people will need every day.
But in a defensive scenario — rain, sweat, injury, or blood — anything that improves your ability to manipulate the slide is a positive.
It’s also small enough that it doesn’t interfere with normal shooting or handling, and it doesn’t add noticeable bulk.
Build Quality and Price
The Deadfall feels solid and well-made. It doesn’t feel flimsy or cheap once installed, and it locks into the slide just like a factory back plate.
At around $15 (pricing at the time of filming), it’s a relatively inexpensive upgrade.
Sintercore was also very responsive when I reached out with questions. I wasn’t asked to do this review, wasn’t compensated, and had no prior relationship with them. I simply ordered it to try it out myself.
Final Thoughts
Overall, I really like the Deadfall.
Is it something everyone needs? Probably not.
Is it something that could be very useful in bad conditions? Absolutely.
For a small, inexpensive part that adds functionality without downsides, it’s a solid upgrade — especially for a defensive or duty-oriented pistol.
If I run into any long-term issues, I’ll update accordingly, but so far it’s been a positive experience.
