Depends on what you want. If you want to increase your capacity from 6+1 to either 9+1 or 10+1 and enable the use the 13 round mag, it will cost a bit more width.

Here is a side by side comparison;

Since you already have the 36 and if you have money burning a hole in your pocket, get a 30SF and you can make your own 30S while keeping other conversion options available to you that a 30S will not be able to do.

 

I traded my G36 for a G30SF and ive never looked back!

 

Get the 30s and have the best of both worlds

When I had the opportunity to buy the 30s or 30sf I bought the later. I like the heavier slide. The main reason to go with a 30 is mag capacity in my opinion.

30s is easier to carry and the recoil isn't bad either

Get the 30S, it holds more rounds and is just as easy to carry and conceal. I have had my 30S since the 2013 Shot Show when it was released and it's the one Glock I own that I won't sell.

 

The width to me is not all that different. Not when it comes to sacrificing 4 rds of 45 acp. I'd go with the 30 gen4. I've looked at both, and held both at the same time. No way I would accept a 6 Rd mag over a 10 Rd anyday.

 

I like my 36. It's thin and it's got 8 rounds in it. It'll do the job and doesn't feel like a brick in my hand. But I could learn to like the 30 too. I complement it with the 26.

Keep the 36, but I do like my G30.

 

Higher capacity, less felt recoil, less distance between trigger/back strap (overall more comfortable in the hand), accessory rail, and overall just... Badass! If you are even considering trading your Glock 36, then you probably should. Of course, I am biased being a proud Glock 30SF owner! I will NEVER part with this pistol. Ever.
