Any Glock aftermarket barrels that will stabilize 220gr hardcast better?

I have a Glock 40 and was wondering if I could shoot hardcast better if I upgraded to an aftermarket barrel. I was specifically looking at the Lone Wolf Alpha barrel.

Many of the aftermarket barrels with cut rifling are better from the cast bullets, LWD used to offer some good barrels before the Alpha line came out.  The Alpha line maybe ok if they have one to fit the G-40's.  KKM is another great product as well.
