I have 2 FN509s. One full size with a PMM Comp. One Mid Size with an RMR. I like the guns and shoot them well, but the stock trigger leaves much to be desired. I have the Apex trigger in the Full Size and it is much better but maybe too light for carry.
IMHO the best G19/G17 alternatives are the M&P 2.0 and the CZ P10s.
