So I just finished field stripping, cleaning, and reassembling my Kahr CW40 after reassembling it I noticed the slide lock is incredibly difficult to engage.  It is only difficult to engage with a magazine inserted.  Before i decided to take the gun apart and clean it the slide lock was stiff but not so stiff I had to hit it with a screwdriver to get it to release.  Tried calling Kahr but they arent open right now

Problem Solved Kahr designed the pistol to be hard to release with an empty magazine inserting ammo solved the problem
