I almost bought a keltec 9mm, can't remember the model. The salesman was showing it to me, talking it up. I went to pull the slide back and it wouldn't budge. after me trying 3 or 4 times, the sales took it from me with some smart comment about needing to know how to properly do these thing, he couldn't pull the slide back himself. He put it back in the case as I smirked at him.
I don't have a good signature.....
