I own a G36. I just put some more rounds through it this afternoon at an indoor range. So far, mine has been a flawless feeder, firer, and ejector. For a Glock, it is thin. The factory specs of 1.13" are only at a couple of wide points (slide release, thumb rests). The actual thickness of the slide and most of the grip frame is right at 1".
The only advantage the G36 has over the G30 is the thinness which also relates to grip size. The grip fits my hand very well compared to a G30. I also don't worry about the 6+1 capacity. In that regard, it is very close to a 1911 pistol and there are a lot of people in this world that are satisfied with single stack 1911s.
Recoil is brisk, but feels like any other pistol in this size and weight class whether it is .45 ACP or .40 S&W. Recoil is really no big deal unless you are recoil sensitive. I have an alloy frame snub nose revolver that has more felt recoil than the G36 when shooting .38 +P ammo in the revolver.
I shoot this G36 weak hand, strong hand, and both hands. I only really notice recoil when I shoot weak hand just because my weak hand is, well, weaker.
For the way my G36 fits my hand, it is a natural point shooter. It shoots to point of aim with 230 grain ammo and I can free hand shoot 4" groups at 20 yards, like I did today. One handed double taps are easy at closer ranges which is satisfying.
I've only had my G36 for 7 months, but it is one of my favorite handguns.
