I have the Parker V1 and, yes, the safety bar can move out of alignment but, on the V1 at least, it can be moved back into alignment.I will preface by saying, for those having great shaves with the Parker V2, carry on. You must've received a good one.
As for me, I jumped into injectors with two purchases, a Parker V2 and a vintage Schick I type (hydro-magic).
My first shave with the Schick was amazing... very close and smooth. As for the Parker, I was leery from the beginning due to what looks like an uneven blade gap or spacial difference between the lower guard and cap. The gap appears greater at the front left and becomes worse as I increase the gap via adjustment.
Sure enough, rough and uncomfortable shaves with the Parker. They aren't even in the same ballpark. It bothers me how the lower guard on the Parker is not a solid piece all the way across, but of course it can't be because that's the part that the adjustment knob moves as you turn it. Below are the two heads compared - Schick G vs Parker V2. Hopefully the uneven gap shows in the Parker photo:

Before injectors, my experience was cartridge, then DE followed by AC shavette and straights. Lately, I'm back to my DEs and injectors. As for straights and shavettes, there was somebody else in the forum who posted that preparing for a shave should feel fun and enjoyable, not like I'm girding for battle. I concur. To each their own though, some blokes love it.
As for injectors, if my only experience had been the Parker, perhaps I would've been disappointed with injectors. For me, the vintage Schick was the far better choice. They are abundant and fairly cheap on the auction sites and as a result of my first great shaves, my collection has grown to 2 hydro-magic, an E, G and I type (non-hydro) and just added a PAL injectomatic. If I was dead set on new and modern, then I'd spring for the Supply w 3 dot plate. I don't own it but those whose opinions I trust speak highly of the shave quality. For me, I just can't get past the form factor, preferring shorter handles on my injectors and DEs.
cheers
In your photo of the V2 the large plate below the safety bar with the round hole punched in it is attached to the safety bar. Try moving the bottom of that plate from side to side and it should move the safety bar back into alignment. If that doesn't work then, yes, the razor is defective.
I have also found when putting in a new blade that the blade does not always seat itself on the two guide post at either end of the blade. This too can be realigned by reinserting the key into the head and using a Q-tip or something like that to push the blade into place.
While I do not have these problems with any of my vintage injector razors I still feel that the Parker Injector Razor is a step in the right direction. There are many new DE razors out there that can't even come close to a vintage Gillette Super Speed but that doesn't stop makers like Parker from trying.
