I use the G400s and it has a groove above my pinky that I keep it on, although at first it was uncomfortable I just got used to it over time. At the time I was looking for a solution and some mice have a pinky finger rest like the RAT9 so if it is a problem for you one of those mice might help.
This is my mouse. I barely use the special buttons (But it supposedly has a good one for scopes.)
I keep it on the higher side of sensitivity.
This week already feels too long, but that's partly because for once, the weather's nice today.
How many buttons are you looking for? I use this: http://www.amazon.com/Mad-Catz-T-9-Gaming-Mouse/dp/B009PHSDBM/ref=sr_1_1?ie=UTF8&qid=1438955776&sr=8-1&keywords=rat+9
There is a cheaper alternative called the rat 3. I have big hands and it really works wonders for me, it has an adjustable length and adjustable weight, i really like it and its got everything you need for an mmo really.
Sure it only has 6 buttons but, do you really need more?.
Keeping in line with a red/black theme, the R.A.T. 9 is a good, and very adjustable, mouse. Here's the link to Amazon http://www.amazon.com/Mad-Catz-R-A-T-9-Gaming-Mouse/dp/B009PHSDBM. I'm sure you can find it for cheaper. A friend of mine owns one, and it's a great mouse.
I wouldn't call this the best.. but it's wireless, adjustable, and 1ms.. https://www.amazon.com/Mad-Catz-T-9-Gaming-Mouse/dp/B009PHSDBM
I'm not sure what your asking but the mouse I use is this Mad Catz R.A.T.9 Gaming Mouse for PC and Mac https://www.amazon.com/dp/B009PHSDBM/ref=cm_sw_r_cp_api_WcaCzbX7T78YW

I had pleasant experiences with my RAT7 (wired version) and RAT9 (wireless). The software is native for OS X. The mice are fairly chunky, and have both adjustable fit and weight.
Main caveats are:
other users reported some mice are not very responsive
battery life on RAT9 is kinda bad
not many extra buttons
I suggest you get the R.A.T.9 mouse. It might not be fast enough for 1+0 bullet though.
I'm a big fan of this one...
I think one of the Mad Catz Rat series has what you're looking for. Might be the Rat 08, but I'm not sure... Anyway, the right side has an interchangeable section which comes with a swap out pinky rest. However, it will probably cost you more than $80 for a brand new one. You could look at a used one.
EDIT: It's the Rat 9 (https://www.amazon.com/Mad-Catz-T-9-Gaming-Mouse/dp/B009PHSDBM/ref=sr_1_2?srs=2529833011&ie=UTF8&qid=1525230412&sr=8-2&keywords=rat)
