What is the big deal reloading for glocks

[MH357]

Whats different for reloading glocks. Some say it can not be done others say no big deal. I know a friend who reloaded a batch of 10mm that jammed a lot in his glock but worked fine in his smith. I am thinking of buying a glock 9mm but don't want anything I have to buy factory ammo for.

Any insight into this??? Obviously people must have more problems reloading for glocks than othe handguns for this to be floating around on the net.
