I picked up a used Kahr K40 online for around $360, I thought it was a great price on such a beautiful firearm. It came in today, and it looks great, very beautiful pistol, and no signs of wear anywhere on it. The only thing that concerns me is that it doesn't seem nearly as tightly fitted as CM and CW series I've owned before. This bothered me because I thought the K series is supposed to be a more premium line than the polymer ones. The slide doesn't seem to go all the way forward/completely flush with the frame (pictured below). If I move the gun side to side, there is also considerable slide movement/wobble - as though the slide is kinda loose on the frame. Every Kahr pistol I've previously owned have been put together so beautifully, very tight, with zero slide movement at all. Is this normal for the K series? How can I fix it?
I've stripped the firearm and given it a very detailed cleaning, reassembled and same thing. Would a new recoil spring help? ... Oh, there also seems to be a lot more play in the trigger than what I would consider normal in the polymer lines.
