Anyone tried a Lone Wolf or KKM 40sw Barrel in the Gen 4 G20?

Just ordered a new Gen 4 G20 yesterday and I'm already excited to shoot it. Looking around it seems like the 40 S&W conversion barrel will save me some ammo costs when I take this to the range.

BUT after watching the videos on the top of this page where weaker 10mm rounds caused problems for the glock employee, I'm wondering if I will need to install a different recoil spring or if the gen 4 G20 is just built for hotter rounds than the gen 3 was.

Any insight?
