I bought a DW valor commander in 9mm and I'm having issues with it. My self defense ammo (147g HST and GD) works in it fine. Range ammo does not. I've tried WWB 115, Speer FMJ 115 and 125, Aguila 125, blazer brass 115 and 125. It's not the mags - I've tried 20ish mags including factory DW, factory SA, Wilson and McCormick. All those mag/ammo combos work 100% in my Springfield RO. What's happening is that the fired case isn't extracting from the barrel and the slide is trying to pick up another round behind it (although it doesn't make it all the way to the rim on the new round). Jams it up real nice. It happens every shot with this ammo.
Extractor tension is ok and it works fine with heavier SD ammo. I get the feeling that the chamber is too tight or the recoil spring is too stiff for the weaker loads and they don't have enough power to cycle the slide properly. But why is the extractor letting go of the fired round in the barrel? Possible a chamber that's too tight (match chamber)?
I only have about 250 rds through it. Should I put another 500 through it and see if it breaks in better before sending it back to DW or should I just send it back now?
What do y'all think?
