I only have two 22 pistols that have never failed me.
A S&W 63 no dash and a Glock 44.
If I were you I'd wait a few more weeks and get an FN 502.
H&H had one for sale a couple of weeks ago.I am a recent new owner of a FN-509. It's beside the bed as we speak with a WML and integral laser. Very fine firearm.
I'm a Ruger Mark series owner having every model since they were put on the market, but I'd sure like a look and a range day with that 502 when it comes out.
