I have a brand new XD Sub Compact 9mm and a brand new LaserMax Guide Rod laser. I installed the laser, when I cock the gun and release the slide slowly... in a controlled fashion with my hand vs. full speed spring action with the lever... the slide stops about 1/32 to 1/16 of an inch from being in position (the "cocked" indicator pin is flush with the back of the slide). Then I have to push it a little to go fully into position (not hard push, an easy push). It kind of clicks when I pop it fully into position. Then the indicator pin is out the back and the slide is flush with the front of the gun, everybody is happy etc. It doesn't have this "problem" with the original guide rod and original springs. If I cock it and flip the lever, and let it go full spring action, it is fine... I hope I described this well, can anyone tell me if this is a problem or should I go put a few rounds through this dude. This gun has never been shot. I'm new to guns, so I don't know much, if you can't tell. Although I learned alot when trying to pick out a CCW. This was a Merry Christmas to me.
