Gen 4 new.
Lubed it up a little and going to try it again. The gun store said it looks fine and they tested with no jamming. I heard if you “limp wrist” :gay these they will fuck up. My Dad shot 3 rounds and then jammed and I know he wasn’t “limp wristing.” I wasn’t able to get more than 1 out without jamming.
They said they will take it back if it is still messing up. I’m going to take video the whole time shooting to show the salesman if/when it jams up.
