My new M&P .40 seems to have a cycling problem. I bought the gun new on Monday morning. I've put 75 rounds through it, and 7 times it jammed up on me. It's hanging up on the loading ramp. With just the slightest pull of the slide, the round lifts up into place.
Is this something that I should contact S&W about, or the store I purchased it from ? I know this isn't good and needs to be addressed.
