He rarely says bad things about a firearm but gives hints if he has reservations. Very understated. Some folks might miss his hints.
Handguns are a very personal item, meaning they are specific to people's hand, grip, sighting technique, etc., and one pistol that doesn't work one individual might be the best fit for another. I appreciate that Hickok45 is understated on his opinions for that reason (as
@drband said), but the glaring difficiencies (price, weight, footprint) of the Hudson H9 and the other strikers out there made themselves known as he wasn't able to get past those and rightfully so. I've seen enough of his videos that if he thought the trade off of the deficiencies of the Hudson H9 were worth the added control firing it would have come out in the review. But those stats he talked about are hard to overcome in today's flush market of strikers.
Hickok45 is one of the best reviewers out there in my opinion. He cuts through the "Tactical Tommy" routine and finds great comparison firearms to contrast with the subject firearm. He was spot on in his assessment of the Hudson H9 at about the 8:00 mark when comparing it to the three other striker fired pistols, the Hudson is twice the cost and about 30% heavier than the Glock 19. I don't own any Glocks but I recognize that new manufacturers of striker fired pistols better take notes on weight, cost and durability when they seek to compete against the many striker fired pistols out there as there are several really good and affordable pistols out there.
No doubt the bore axis is low on the Hudson, you can see that right away, but bore axis isn't the end all be all. They added significant weight over the other standards for striker fired pistols and made it's profile less conducive to holstering in my opinion with the deep well that houses the mainspring under the barrel. It almost seems that one could have a Glock 19 with a mounted light on a pic rail and be about the same size and weight as the Hudson, that's heading the wrong way in my opinion. I bet if you added the 30% extra weight to a Glock 19 in the right areas one could eliminate some muzzle flip just from that as well.
This all coming from someone who doesn't own a Glock but can respect it for the fact that it's "a" (not necessarily "the") standard for striker fired pistols.
I took Hickok45's review as that the Hudson H9 didn't stand out amongst the heavily populated striker fired pistol market, and based on the MSRP of $1,100 I think he said, and the extra weight and larger footprint under the barrel, a pistol better stand out for being double the cost of the competition.
If I need a more technical review MAC provides that, he is another great reviewer.
