Blackhawk Hi-capa serpa
 

Anyone knows where I can get a real Blackhawk serpa that would fit a Hi-capa? Do they even make real ones that fit Hi-Capas? Thanks.

You have to get a 1911 one. You will have to modify it to fit, mostly in the trigger guard area since a 1911 triggerguard is round and a Hicapa (which is based off a STI/2011) triggerguard is squared off. The slide may also be a bit too wide for the holster and you'll have to modify that somehow, perhaps by getting it hot and squeezing it out a bit.

You could also get the tanio koba grip. It has a rounded trigger guard and is tones more comfortable than the original grip.
Pretty easy to install too.
