yah they are, from my understanding hi-capa is any 1911 platform with higher capacity mag then usual, double stack magazine or what ever they call it. all it is really is a thicker/fatter grip to occupy the bigger magazine.
in the case of that black “1911” CEH is releasing, it is not a “colt 1911”, or IMO not even a “1911” for that matter, it’s “real steel” version is the Para Ordnance p14-45, 14 round mag chambered in .45 ACP, this company was the first ppl to make an upgrade kit (lower frame with fatter grip and higher capacity mag) for 1911 during the 80s, then later started releasing their own version of the higher capacity 1911 reverence.
if anything this baby should be called a 2011 as that’s what is usually used to refer to hi-capacity 1911 variance. like the TTi 2011 Combat Master.
they called it “1911” for the same reason toyota called that little toy car 86, better publicity
