Thanks for all the great info guys!! I'm definitely not looking for a reason to spend money. In fact, choosing the best spring, i thought, would help me become more accurate more quickly and, in turn, spend less on ammo. Let's face it, ammo is the expensive part about 10mm. I'm a big fan of stock glocks. I have 8 and the only thing aftermarket is night sights. Just read alot here about spring weights and wanted the experts opinions. I'm thinking about a 19# Stainless steel and seeing if there is any difference.
Thanks again for all the feedback!
