I am sticking to what has a long term track record of flawless performance for me over many years....the G26.
Best of both worlds. Durable and dependable. 10,15,17 or 33 round mags.
Unlike the new single stacks which are still not proven, I know I can shoot thousands of rounds thru my G26, and run it hard with +p ammo with no issues.
Since you have a G19, then leave all those other single stack poly sissy guns alone
Just get the G26 and be done with it.
