My 21SF is my favorite gun these days. It is very accurate and feels good in my hand.
I have the ambi release which is not the most popular feature on Glocks, but I haven't had any problem with mine. You will like the 21 SF if you like the 36, it is actually easier on the recoil because of the full size grip and frame.

Would you care to elaborate?

I can. I've shot a stock 23 and a highly customized 23 at the same time. Took turns shooting a mag in each. Other than a better trigger on the one, I could not tell the difference. If it were not for the slightly lighter trigger pull on the one with all customized parts in it, I really didn't see much difference in how they shot or felt. So I say that a stainless guide rod is probably more dependable as far as not breaking or chipping or whatever, but it doesn't do much for how the gun shoots or feels.
