Thank you so much 
Everything is intended. I picked this replica that way and was trying to achieve the same effect prior this one but we ended up with something totally different.
I wanted to give it a more menacing and aggressive look with in mind the Hardballer from Codename 47 and the real one and so here it is.
I believe all brushed wouldn’t give the same feeling of a killer’s weapon even if in the wallpapers it actually looks good.
Perhaps someone could photoshop those with the same color tone mine has to see if it actually looks better?
Instead speaking about all the technical stuff I don’t really believe the folks at IOI give it that much of a thought.
I’m sure they consult someone specialized in weapons but most of it if not all is just pure aesthetics that is meant to look good.
Yes for sure they had in mind with the advantage of the extended thumb safety and slide release, about choosing a 1911 for it’s practicality I think they just liked how it looked.
If you haven’t seen this yet I created a Silverballer encyclopedia rich in details about everything about it and how it evolved.
