I have an older AA kit on a G17 and I recently bought their threaded barrel with 1/2x28 adapter. I added Mepro adjustable sights but the OEM would likely be OK. It has worked great for me with an AAC Prodigy but I only have a few hundred through it since suppressed. I have read of trouble using the AA kits suppressed but it seems to happen with the heavier cans. Reliability has been excellent, the same as before the can. Ammo preference is unchanged, Remy Golden for cheap and CCI Mini-Mags for reliability/accuracy. I have not tried other loads suppressed. Everything has stayed subsonic so far but I think it is on the edge of being transsonic. I have not been following the SUPPRESSOR section of the ARMORY on this site much lately but there has been a few other threads on this subject you might find. It makes a neat 22.
