Just thought I'd contribute to the forum with some insight. In case anyone was perhaps in the same situation I was in... I already own a BT DOH holster (and I admit, I have a bias, as I love my DOH). Wanted to pick up a Black-Ice for my new G34. Read a lot of reviews, watched a lot of youtube vids, etc... Kept reading/hearing from people that there's really no difference between the three, so I chose the cheap route and ordered a Revolution holster. My friend, also a new G34 owner, splurged and went the Black-Ice route. I figured IF there's no real difference between them, then I'm saving myself ~$40. I realize now that there is a difference. It's pretty noticeable. Is it worth a $40 difference in price (between the Revolution and Black-Ice)? That's up to you. Keep in mind that I'm using my old DOH as a baseline when comparing the Revolution and Black-Ice. And so, I feel like, simply put, the Revolution is a tiny step backwards and the Black-Ice is a legitimate step forward, from the DOH. The Revolution included a paddle attachment and a 'stingray' (direct belt) attachment. My friend had options when ordering his, so he ordered his Black-Ice with a Tek-Lok attachment (one that I had with my old DOH and would still recommend to anyone, by the way). So right off the bat... different attachments included with each. Quality is the same with all three (in my eyes). It's Blade-Tech so I find them all to be of good quality. Good retention screws, no wiggle or 'loose' parts, good adjustment screws, good material, thus overall good quality. The main difference lies with the draw. Again, using my old DOH as a baseline... I really liked my DOH because it was a really smooth, easy draw out of the holster, with a nice solid/audible click when re-holstering. The adjustment screws on the holster allowed for customizing how much 'retention' I wanted (i.e. how difficult it was to draw the gun out of the holster). With the Revolution... I feel like the retention system is a bit clunky, for lack of a better word. It feels like there's more material grabbing onto the gun and so even when adjusting the adjustment screws, it may be 'looser,' but it still feels clunky. In comparison, the DOH feels more smooth and it feels like there's less holding onto the gun and so even though they both equally retain the gun well, the draw with the DOH just feels more 'smooth.' Now when you compare the Black-Ice to those two, it's feels even smoother. Is it light years ahead of the DOH? No. But still, noticeably smoother. The main difference I felt between the DOH and the Black-Ice is in the draw angle. The DOH is a straight up-and-down draw (like the Revolution), whereas the Black-Ice is cut so that it allows for a forward pull angle as you draw the gun. I guess one could argue that the cut allows for a 'faster' draw (depending on how you define a 'fast' draw), since there's theoretically less movement (e.g. shoulder hike) compared to a straight up-and-down draw. You can argue about proper draw and training, pros and cons, etc, etc,... Not here to do that... so again... just stating that 'in theory,' one could argue that it would allow for a 'faster' draw. In the end,... for me, personally... Even though you can't go terribly wrong with any of the three, I probably wouldn't recommend the Revolution (regardless of the financial savings). I feel like the 'clunky' draw isn't really worth $25-$40 in savings. By the way, at this time I'm referring to prices of ~$30 for the Revolution, ~$55 for the DOH (if you can still find one), and ~$70 for the Black-Ice. I'd say... if you can find a DOH somewhere, go with that... but if it's simply between the Revolution and the Black-Ice,... shell out the extra $$$ and go with the Black-Ice. Hope this helps...
