After posting the SR1911 10MM Unboxing video https://www.youtube.com/watch?v=R9gbLuDQqFY the emails started to come in asking about chamber support.

Being curious myself I decided to compare 4 10MM 1911's,
Colt Delta Elite
Ruger SR1911
Para Elite Hunter
Kimber Camp Guard 10

I do not have the best of camera gear but hope this helps.
