Started having some feeding problems where spent rounds ended up sideways in the chamber without ejecting completely. When manually working the slide, noticed that the last 1/4" felt like it was dragging because it took extra effort to pull the slide back that last 1/4". Called HP and was sent a free new stryker along with the two associated springs. USPS tracking shows that the parts took 12 days from shipping until delivery to me. Put in the new parts, yet the original problem described above continues! My guess was that the firing pin was somehow bent where the slender part joins onto the base of the stryker. But installing a whole new stryker resulted in the very same problem . . . Ideas? I'll be calling HP tomorrow.
