OK - Here's how you check for straightness. I don't think it should have been bent from what you describe, but........

You put your sight on center of a large paper target and shoot 5 rounds and see where actual point of impact is. Then, turning upside down and shooting thru your legs, again put your sight on center of a new large paper target and shoot another 5 rounds. If the POI changes 180-degrees - it's bent.
