Im still new to handguns....been a long gun my whole life and Ive run across a issue im curious about with my 21. I just got some federal hydra shoks and when I load a full mag it takes a good amount of force to load the mag. It also takes a good amount of force to pull tge slide back and chamber a round. Is this something that can cause a problem with my gun...or is it a "breaking in" issue. It doesnt do it with some plain jane cheap range ammo...only the hollow points. The gun is new with only about 50 rounds through it. I just wanna make sure im not gonna harm my new favorite weapon in any way. Thanks in advance.
