I have not read much (if anything) bad about FNPs. If you wind up getting it, enjoy!
If not, and you go back to looking at Glocks, here's something to consider when choosing a G19 vs. a G26 (especially a Gen3 or older G19): whether the grip forces the barrel high of your natural point of aim.
Here's what my old G19 looked like when I gripped it:
In particular, note how the bottom of the backstrap (just to the right of the Glock logo) pushed into the fleshy part of my hand:
This actually forced the barrel to point high from my natural point of aim. I had to cock my wrist to get the barrel to point back on target.
However, this is me holding my G26 (I traded the G19 for the G26):
Don't have the same problem. The G26 points much more naturally for me and it's easier to aim. Even with a 15-round mag from the G19 and the grip extension from A&G, it still doesn't push into my hand the same way a G19 does.
On the other hand, if that's not a problem for you, then disregard this post entirely.
Good luck!
