Recently purchased my new shield .45 and I have my first issue ever with a m&p product but after firing under twenty rounds thru it I broke it down to clean. Recoil spring and barrel hit the floor there is absolutely no tension whatsoever I called smith and there sent new spring but problem is still there it just sits there and will fall out untouched. I plan to call back Monday morning but was wondering if anyone else has had this issue and how did you correct problem
