I'm not going to start another thread about FTE's or FTF's. But today I took my new G19 gen4 out for it's maiden voyage and had a little issue that puzzled me. I would shoot through a magazine and the slide would lock back as it should. Then I would drop the empty mag, insert a new full one and with the palm of my left hand, give the mag a little bump to make sure it was seated properly. Then the slide would release and chamber the 1st round. This seems like it could be a good thing, but I'm pretty sure it isn't supposed to operate that way. Any idea what I was doing wrong? Should I not bump the new mag to seat it? Thanks in advance for your help.
