Question for anyone who owns a SA XD9?

[Zor Omega]

I took my XD shooting for the first time today. I bought a lot of different kinds of ammo jsut to see how they fed ( which all 244 rnds did perfectly). I shot a couple of Cor Bon Powrball 100 grain +p rnds through it, and when I did I noticed some orangish and slight bluish sparks coming from the muzzle. Is this normal? It did not do this for all the rest of the rounds I put through it except for the powerball ammo.

Totally normal. Make sure you only fire a couple of those Powrballs on the range. Those are expensive
