I don't know why they rebranded the B6 Hawk, but I can make a good guess... I think was because of the confusion with the same model number on both steel and poly guns. It confused me at first, but I caught on quick
SAR pistols are great shooters. I even carried my B6P for a while after I decided I really hated my previous EDC, while O waited on my P100. The B6P is every bit as accurate as my P100, and maybe a skoshe more, but that probably has more to do with barrel length. My ONLY complaint with the B6P is the trigger. Not the way it functions, but the way it is made. The corners where the trigger flat breaks to the sides are brutally sharp. This is not bad on gun you only shoot occasionally, because it ensures a positive grip on the trigger, but this not the best idea for a range gun. I get around it by putting a Band-Aid on my trigger finger when I take it out to the range. Anyway, I think I heard they have improved that trigger.
Apologies to the OP for drifting off-topic slightly (but you might find this useful as well) and to you sir if I offend.
I've seen the complaints about the B6P trigger having sharp edges and I asked myself "How big are these people's hands?". I'm 5'4" with small hands and I find that the smaller the pistol the easier it is for the trigger to creep into the crook of my finger. While it feels natural it can also be uncomfortable if the edges aren't rounded. I have to consciously remind myself to place the pad of my finger squarely on the trigger because of this, as well as causing me to pull my shots off-center.
With larger pistols like my .22 TCM RIA 1911A2 I don't have that problem because the larger grip doesn't allow my finger to go around the trigger as far, the pad of my finger sits where it should on the trigger. I have no issues with the B6P trigger myself but I can see where it might be annoying to someone with larger hands.
Having rambled all that, there's nothing a piece of Emory cloth and a Sharpie can't fix on those sharp trigger edges.
