DY9 Chassis Kit - One Pistol. A Whole New Platform.
10th Aug 2026
Product Launch / DY9 Platform
One Pistol.
A Whole New Platform.
The Derya Chassis Kit takes the DY9 you already own and drops it into a rail-equipped, brace-stabilized chassis in seconds — no gunsmith, no permanent modifications, and your pistol comes back out exactly as it went in. Available now in the USA.
01 / The Concept
Drop In. Lock Up. Go.
The Chassis Kit is a polymer-bodied conversion chassis with metal rails and reinforcements exactly where the stress lives. Your compatible Derya pistol drops into the chassis and locks — no fitting, no tools on the bench, no permanent modification of any kind. What you get on the other side is a noticeably more stable, more controllable, more accurate shooting platform with real mounting space for the accessories your pistol never had room for.
At 34.25 ounces, the kit hits the balance point on purpose: enough mass to settle the platform and soak up movement, without dragging the whole package into rifle-weight territory. The muzzle device, charging handle, and folding brace are polymer — keeping weight where you want it and structure where you need it.
Polymer + Metal Build
Polymer body keeps the weight honest. Metal rails and reinforcements carry the load at every mounting and stress point.
Side-Folding Brace
The stabilizing brace folds to the side and locks securely — 14.5" for the bag, 22.25" when it’s time to work.
Full Picatinny Real Estate
Uninterrupted top rail plus side rail space for optics, lights, and lasers — run the setup your pistol slide never could.
Flip-Up Sights Included
Flip-up front and rear sights come with the kit — you’re on target out of the box, optic or no optic.
Derya Sling In The Box
Every kit ships with a Derya-branded sling, so the platform is carry-ready the day it arrives.
True Drop-In Design
No permanent modifications, ever. Your pistol goes in, locks up, and comes back out exactly as it went in.
02 / The Numbers
Spec Board
Width measurement includes the side-folded brace and the protruding charging handle.
03 / Compatibility
Know Your Fit
Locks Up
These models drop in and lock securely — the fit the chassis was built around.
Will Not Lock — COMP Models
The compensator creates too much gap between the pistol and the chassis, and the kit will not lock. COMP models are not compatible — no exceptions.
Fit Not Warrantied — DY9Z
The DY9Z may fit if forced very tight, but we do not warranty the DY9Z fit and recommend against purchasing this kit solely for a DY9Z.

05 / Shipping
Where We Can’t Ship
Derya tracks the law in every state and ships everything that is legally permissible. Because of state and local restrictions on brace-equipped conversion chassis, we cannot ship the Chassis Kit to the following states:
No-Ship List
Orders with a shipping address in a restricted state will be canceled and refunded. This list reflects restrictions known to Derya at publication; laws change, and additional local restrictions may apply even in states we ship to. The buyer is solely responsible for confirming legality in their jurisdiction — if in doubt, contact Customer Service before ordering.
“No gunsmith. No permanent modifications. The pistol you carry drops in, locks up, and becomes the platform you shoot.”
Read This Before You Buy
This kit ships in a stabilizing brace configuration only. It is not a stock. Adding a vertical foregrip or converting the brace into a shoulder stock may change the legal classification of the firearm under the National Firearms Act.
The buyer is solely responsible for compliance with all federal, state, and local laws.
