Brand new owner, first S&W and bought a Sheild compact with Crimson Trace laser. Bought this due to many high praises and when I brought it home it was impossible to get more than one shell in either mag. I took them out to the garage and put a drop of oil on several key spots and then took a 7/16 open end wrench and worked the slide up and down about 50 times. I was able to then get 5 shells in the 7 shot mag. Are stiff springs normal and if so what mag loader do you guys use? I paid $440 out the door for this set up so I think I did OK.
