No Polymer guns. You can drive a jeep over a 1911, CZ, or Beretta and it will likely still work, a Polymer frame, good luck. And mind you, this is coming from a guy who carries a M&P or a Glock 36 daily.
I don’t know about that. My m&p compact has been beaten up and heavily used by my kids and it’s still a sure thing. Rarely any misfires/jams. My buddy dropped his glock and the thing cracked. Not this m&p. Maybe it’s a new type of polymer? On another note, the feel of the m&p in my hand is better than my other guns. That’s why it’s my daily carry choice.
