KKM barrel for G17. Stock or extended length?

I have a G17 and am going to buy a KKM barrel for it. I reload and shoot lead bullets. The first thing I did was put a KKM barrel in my G40 MOS and it is the most accurate handgun I shoot.

So, I will order a KKM barrel for the G17 but can't decide whether to get the stock length or extended length barrel (6"). It will be used mostly at the range although it might be used occasionally hiking in a chest pack.

I'm wondering how the balance will feel with the extra weight at the nose.

Any...
