The matrix arms delta rmr dlc slide for Glock 17 Gen 3 dominates every build list for a reason. First, we machine it from 17-4 stainless. Then we cut a true direct-mount RMR pattern—no plates, no nonsense. After that, we finish it in deep black diamond-like carbon for extreme wear resistance.Next, you choose flush or threaded match-grade barrel. Finally, we install every internal, test-fire it, and ship the same day. Consequently, the second your matrix arms delta rmr dlc slide lands, you simply drop it on your Gen 3 or Polymer80 frame and go punish steel.Aggressive front and rear Delta serrations, lightened side windows, and that armor-grade DLC finish laugh at holster wear. Same-day unmarked shipping. No FFL, no wait.What You Get with the Matrix Arms Delta RMR DLC SlideMatrix Arms Delta slide – black DLC coatedDirect RMR / Holosun 507C-508T cut (zero adapter plates)Your choice: flush crown or 1/2×28 threaded barrelComplete internals recoil spring assemblyTest-cycled and function-checkedSpecificationsCaliber: 9×19Compatible: Glock 17 Gen 3 & PF940v2Finish: Black DLC (diamond-like carbon)Optic Cut: Direct RMR patternWeight complete: ~22 ozHow to Install This Complete Upper (30 seconds)First, clear the firearmThen punch out both frame pinsNext, remove the old upperAfter that, drop the new slide onFinally, push the pins back inHow to Disassemble for CleaningFirst, lock slide back and pull takedown tabsThen ease slide forward off frameNext, pull trigger (gun clear!)Finally, remove recoil spring and barrelCompatibility of the Matrix Arms Delta RMR DLC100% drop-in on factory Glock 17 Gen 3 framesPerfect fit on Polymer80 PF940v2Works on Lone Wolf, ZEV, Nomad, and all true Gen 3 framesWill NOT fit Gen 4 or Gen 5 without adapterFrequently Asked QuestionsDo I need adapter plates? → No – direct RMR cut.
