I purchased a Gen5 G19 MOS, and it looks great (paid way more than I probably should have, anyway) I noticed a strange issue that I’ve not seen on any other gen Glocks. When the slide is locked to the rear on the Gen 5, the firing pin freely moves back and forward, even through the breech where it ignites the primer (regardless of whether the trigger is forward or backward). Is this normal? Is this something to worry about? My Gen 3 doesn’t do that, the firing pin is totally blocked. Is there a reason for this or do I have a lemon, because I wanted to buy a second one. Thanks guys, I really appreciate your help.
