OK - I figure 10 guys will post that hand cycling is not representative of actual shooting. I also must be a fool to start a thread about hand cycling and weak ejection. But WTH - I know that many times a gun will not eject cartridges "properly" when you hand cycle the slide - some will jam / fail to feed - but they will function just fine when you shoot them. What about the Glocks with weak ejection /BTF? If you load up a mag and try and hand cycle through it - what happens? Seems logical if a gun WILL hand cycle rounds out and to the right with good results - it would also function when you are shooting. I just got a FEDX delivery of 230 GR Federal HST - so I hand cycled a mag through the (so far flawless shooting) GEN4 G21 - Holding the gun over a bed - I racked the slide 14 times - Loaded the first cartridge - and then ejected all 13 rounds into a nice neat little pile about 2 feet from the gun. Anyone with a weak ejecting / BTF Glock ever try hand cycling a mag? What was the result?
