I bought a 301 Beretta semi automatic a few months ago. At the time, I was under the impression this gun was not modified, so only lead shots were used.

The seller also threw in a box full of shotgun shells...which I didn't bother looking at until yesterday. While going through the bag I found several high velocity Steel shells.

So now I have no clue if this gun has been modified.

Is there a (good) shop I can take my gun to, to figure it out? I'm in Edmonton.

FYI, there are no chokes, the gun looks like it just came out of the factory.
