My friend's is getting some sparks out of the muzzle of his CZ-75 when using Brown Bear 9mm ammo. Is that cause for concern?

i think it's normal. I shoot WWB and i see sparks sometimes.

The 'sparks' are powder that waits until it leaves the muzzle to burn.

Nothing to be concerned with.

Not of concern in itself, but take care around flammable material.

What are you doing?! Take some pictures! :p

The Russian steel-cased ammo, both pistol and rifle, is NOTORIOUS for inconsistent powder burn and heavy sparks from the muzzle.

To those that haven't seen it, it makes the flash/sparks from WWB and such pale in comparison. It's quite the sight, if you're firing in a darkened indoor range.
