Just picked up an FNP 40...

That's not good news. I hope the one we have doesn't start.

It did not hurt function at all though. I have found that some of my 92FS mags rattle slighly as well but again no issues.

I didn't figure it would. I just hate sounding like I'm packing tic tacs.

I have so many FN guns I am actually getting rid of my FNP40 that sits in my safe. I too have a trading addiction and my target is a nice M&P in 40

That should be an easy straight up trade. Just shot a neighbors M&P sub 9mm. Very nice shooter. I liked it more than I thought I would.

I spoke with FN's customer service today about my mags that rattle. I was told that the rattle is normal and there is no remedy. I was then told that the gun was originally designed for combat and extreme conditions ie .extreme temperature changes sand, dirt, or any debris that could cause the magazine to get plugged up. I asked why it was a problem with the .40 and not 9 or .45. his reply was they all rattle at some point and he does get calls on other calibers rattling.
