are you talking about this little guy?
We've only had one, maybe two cases where the pin in the BHO shaft was bent... the one case that I know of was a guy who admitted he was jamming his magazines in fairly hard. I don't think this is the case with you, but that's one thing that can cause it.
Also... on the side of the magazine there's a "bump". If that bump is a little too worn down, the magazine can sometimes push up past the mag arm. This could also cause the pin to bend some. Usually the rails would stop it from going up too far, but there may be a marginal space wherein it can bend the pin.
That's really all I can think of. If you'd like, I will mail you a new pin. Check your magazine first, though. We need to figure out the problem before we end up bending another one.
Also, the pin... Is it black or silver?
