Picked up a new SD9VE, took the mother in law out to shoot it. We only put about 70 rounds through it. I'm hoping the issues clear up after a couple hundred rounds.
Are these common problems during break on with this model?

Had 3-4 failure to feeds.

About the same number of stove pipes, that may have been mil limp wristing though.

Pistol not going to slide lock after last round, but does when pulled back manually.

And the empty brass comes straight back, lands on right arm, chest, face and a couple went in the hood of the sweatshirt.

Other than that, fires real nice, just hoping these are break in issues.

Input?
