I have multiple M&P's 2 9c's, 45c, FS 9 and Shield. The only one that exhibits this is the Shield. If I dry fire the gun it fires great, but if I put downward pressure on the slide as I try to dry fire the trigger will not release the striker. Now I am guessing this is due in fact to the smaller size of the shield and clearance issues but curious if mine is the only one that does this. Thanks.
