Hey y’all. I recently became a proud owner of a PPQ M2 5” and M2 navy SD. I tried it at the range for the first time yesterday and both shot beautifully. I did, however, have two instances of a ftf with the 5”. Both times it was only the first round of the mag where after racking there was no bang. LCI was red. I could easily rack the slide and eject the cartridge. Both times after ejecting the cartridge the gun didn’t return to full battery and needed a tap. The rest of the mag was flawless. Both times I located the round, there was no primer strike and after reloading it no issues firing them. I had no issues mid magazine. I did get 2 after market Walther magazines and being new to guns I didn’t use the slide release in these instances when racking. Is this something to be concerned about? Does it seem to be user error with improper racking, a magazine issue, or something else? Thanks for the help.
