How many rounds does it have through it? I don’t have any experience with DW, but I’ll say my first Kimber Ultra II was like that at first. I mean it hurt to rack it, but after 50 - 100 rounds it became way easier to rack the slide and no trouble since. Also, after my first break in period I disassembled, cleaned, and lubed it wet again. You might be surprised how easy the combination of the two will make it.
