My 9mm Shield EZ does not rack after each round fired as it only comes back but must be pushed forward with my thumb after each round. Is this a problem or common after years of use? The weapon was deep cleaned and the problem persists
If the gun doesn't come back into battery after a round is fired, you definitely have a problem. The first thing I'd do is give he gun a thorough cleaning, especially making sure there's no grit on the sliding surfaces that slows down the slide. If it still stays out of battery, send it back to Smith and have them fix it. I'd try and take some video of the gun not returning to battery when shooting, and send that to Smith.
Did you buy the gun new or used? How many rounds have you fired through the gun? Has the gun been lubricated after the “deep cleaning”? What do you mean by that term?
As mentioned above- weak ammo, recoil spring issue (broken coil or weak spring), lack of proper lubrication or all of the mentioned items. JMO
Did the trouble only begin after the thorough cleaning...was it cleaned in an ultrasonic cleaner? Those can take off every bit of lube; make sure the gun was properly lubed before reassembly.
