Purchased new Smith and Wesson 41, two factory and one online purchased magazines. Went to range for first time with them and after each shot, the magazine would drop as if release button was pushed and the firearm would not fire until I manually pushed the magazine back upward. Thought maybe the exposed spring where the release clip catch goes into magazine to hold it in the magazine well and after each shot, a round would move upward causing the spring to catch the magazine release clip to drop the magazine. Waiting on Smith and Wesson to return email, will call tomorrow.
