Aftermarket barrel vs. Sight radius

[thomashoward]

Hello,
Just curious.I'm picking up my G20 tomorrow.I plan to use it with cast 200 gr GC bullets with an aftermarket barrel for backpack hunting.
Question is if I get a 6-6.5 barrel the sight radius is still limited by the length of the slide .what advantage is a 6" barrel besides increase in velocity. or is that the whole point
thank you

[runfiverun]

pretty much it.

A bit more muzzle velocity, but at pistol hunting ranges the marginal effect on your game is not likely to be significant.

So I'm thinking "tactical" length Lone Wolf which would be a compromise between the 6-6.5 and stock length
