I purchased the M&P Shield about 4 months ago based on all the good reports. All of you who keep saying 'run some rounds through it' need to listen to ALL the people who are saying there IS a problem with trying to "RACK" the new shield. It WILL get a little better after a few hundred rounds. That is not the problem. Try to Rack one my friends.... (smile) I believe S&W are sending out new "weaker" springs now for people who are having THIS problem.......Shoot it. It will loosen up.
