I have a Glock 36 and I found it difficult to shoot comfortably with the stock magazine butt plates. It never really pinched my pinky--there siply wasn't room for my pinky at all, and trying to hold it properly to control the muzzle flip was very difficult.
I replaced my buttpads with Pearce +1 grip extensions. Not only do they give me a LOT more real-estate for my fingers to grip, but they seem to fit very well with the bottom of the grip, and haven't pinched my fingers.

I don't see the point of the +0 buttpads. They add length to the grip but give you no extra capacity. What's the point in that? If I'm going to pay $9 for a mag extension that adds nearly an inch to my grip length, I want to get something more than a comfy pinky rest out of the deal. If I'm carrying the gun loaded, and toting an extra mag that gives me 7+1 in the gun and 7 in the spare mag. Those two extra rounds may make a BIG difference someday...
My Glock is my "foul weather gun", when it's cold or rainy (and I'm wearing a coat). I have a CHP, so covering it up is OK. When the weather is nice enough my main carry piece is a Para Ordnance P-14.45, so I'm used to a big, heavy gun with a long fat grip. I'll admit that the subcompact configuration of the Glock 36 with stock mag bases feels REALLY small in my hand, but with the Pearce +1 bases, it feels more like a "full size" handgun, and is much easier to control.
And two other added bonuses are that the empty mags drop faster when ejected due to the added weight of the Pearce extensions, and reloads are faster because they Pearce bases make the second mag easier to pull out of it's carrier, and easier to handle while reloading.
I can't speak to other brands of Glock 36 basepads. I have never used the Scherer bases, or any other brand. I liked the looks of the Pearce bases, and the fact that they are made here in the USA also influenced my choice...
Good luck finding a solution. I would recommend trying the Pearce +1 basepads though. They work well for me.
