P7M13 Magazine problem?

[Louis Davis]

Funny, one of my P7M13 magazines allows the rounds in to to rattle a bit when shaken back and forth and when loaded with 13 or 11 or 9 rounds. (Not 12, 10 or 8).

Anyone else have this problem?

Alot of double-stack mags do that. Normal.

Both of my M13 magazine seem to do that. Funny I never noticed...
My other pistol mags seem to behave similarly.

Thanks. Funny, not real good for stealth. Good to hear it's normal anyhow.
