DY9

The Derya Arms DY9 is a semi-auto pistol chambered in 9mm.

Striker fire reliability with a strikingly friendly price. The Derya Arms DY9 is a semi-auto pistol chambered in 9mm. It features a 3.86" barrel, polymer frame with changeable back straps, and Truglo fiber optic front and green rear sights. It also has a firing pin block and anti-drop trigger block for safety. The DY9 is available with:

  • 10 or 15 round magazines

  • Firing pin block & anti drop trigger block

  • Black Melotine finish

  • Polymer and changeable back straps

  • Truglo fiber optic hi-vis front and green rear sights

Compatible Magazine 

Glock long magazines such as 30+ rounds will fit because the magazine will not protrude on the magwell. 

When the magwell is NOT attached, the G19 - 15rds mag and G17 – 17rds mags will work.  But, if the magwell is attached, the basepad restricts some G19 mags to go all the way in. MOST magazines for Glock 19 work with the pistol but is not guaranteed (I would recommend to review some of the youtube Derya DY9 reviews where they test aftermarket magazines for Glock 19).

Derya Magazine basepad for DY9 can be installed to any magazines for Glock 19 and it will work if magwell is installed.  Link: https://derya.us/magazine-base-plate-dy9/

Material used and Finish process 

For material used, DY9 slide is forged 4140 steel. Barrel is 4140 Annealed Extruded Steel (heat treated, followed by crack inspection, then drilling, and finally machining).  For frame, we use a certain formula for premium polymer frame.

For finish process, all DY9s slide and barrels are Melotine finish from Turkiye (in house) and Nitride (US Name for Melotine) for USA made (not in USA factory). If your gun is Cerakoted or Ceramic Coating, we melonite first then cerakote for ultimal performance. All polymer type parts are mainly dyed with the color (that color throughout frame).
