When my G19 was brand new, there were a few times when it would not feed Federal HST if I tried to close the slide using the slide stop. It would always feed by racking the slide. Never a problem with fmj. After several hundred rounds of fmj it fed reliably recently when I would chamber a Federal HST by closing the slide using the slide stop. I think these guns wear in a little, and the fmj's probably have a slight polishing effect on the feed ramp.
I really like the gen 4 G19, I think it's very reliable and accurate.
