I prefer my G42 to my 442. I get two extra rounds in the pistol (6+1). The sights and trigger are better. The recoil is lower and I'm more accurate with it- especially in strong hand only rapid fire. The G42 is about an oz heavier but also thinner. Reloading is faster and the spare magazine is easy to carry.
I use Hornady XTP JHPs and a Uncle Mike's #4 pocket holster.
