Good well built gloves, sizing can be odd...? mis-size? - Blackhawk S.O.L.A.G. HD w/KEVLAR

I printed out the Blackhawk sizing chart to make sure that the gloves would be a perfect fit (As I live in Australia and returns are always a nightmare that I dont want to deal with, as it ends poorly a vast majority of the time) and they are a perfect fit.... for the most part.

I have similar sized gloves with me that I compared them to. Every dimension matches up in comparison except that for whatever reason the thumb length on the Blackhawk is 1cm too short of what it should be proportion wise. I have 3 pairs of gloves with me and all the proportions are the same and match up with each other except for the blackhawk gloves which for some reason have a shorter thumb length for the same dimension glove. Every glove was 13.5cm from.tip of thumb to the velcro on the wrist except the Blackhawk which was 12.2-12.5cm and the difference in room is noticeable.

Its a bit odd to me that it would be done that way, Im going to keep them and wear them in and hopefully the leather stretches and settles slightly larger with use but I had to point that out. It is restrictive when moving the thumb away from the palm like for a thumbs up (no problems with forming a fist because the outside is nylon). Theres no issue with quality or materials, but this sizing problem is the 1st of its kind Ive ever had after using a manufacturer sizing chart. Maybe they need to look into that...?

I dont know if mine was just a dud or a mis-proportioned cut for its size spec or something? But if you dont get this problem I can totally see this glove being an incredibly good piece of gear that I wouldnt hesitate to reccommend.
