Love my 30S, easy to carry and its a pretty good shooter. I have 2 issues with mine that somewhat annoy me, but are easy to deal with.
1. it has just a SLIGHTLY heavier trigger than my 19, 23, and 21. This only affects me if I've been shooting them and go to the 30S, I'll jerk a bit until I get used to it.
2. it pinches my pinky when shooting hotter ammo, after a few boxes it really starts to annoy me. No issues with weaker target 230 grain ball.
I added TALON rubberized grips (helps a ton with comfort) and the Vickers Tactical Extended mag release. Both of those put it up to Gen 4 comfort status for me.
Also get a good mag loader, like the UpLULA if you want that 10th round in those mags to start.
Edit: As to recoil, it jumps just a tad more than my Glock 23 and a hair less than my 21. Very pleasant to shoot IMO.
