Hello....new to the Forum. I just purchased a Ruger LC9s pistol. Since only 1 mg came with the pistol, I purchased another one on Ebay and the seller claimed the mag worked for both LC9 and LC9s pistols. I received the mag and it will not self eject from the gun....I have to pull the mag from the pistol as I press the mag release. I suspect the mags (LC9 and LC9s) are not interchangeable (even though seller claimed it worked fine in a LC9s). Can anyone help me with this issue? Thanks
