Reader “MJ” sent an e-mail in which he voices his confusion over the proper use of the terms “blowback” and “recoil operated.” He went on to say that he had completely failed to understand why the barrel on his new Ruger LCP was flopping around. Enough similar questions have come my way that I think it's probably time to revisit this business of how semi-automatic pistols work.
