Thanks for responding everyone!
Yes the slide is as Adolf Hamster replied, a bolt style due to the fixed sights, with an internal hammer such that of the Colt Model 1903 Pocket Hamerless pistol.
That isn't a selector/safety behind the trigger but a fixed thumb rest, was trying to copy the Tanfoglio styled thumb rest to go along with the front facing gas pedal thumb rest (taken from Beretta 92X performance pistol) for a more proper grip that racers use. It had printed oddly and the placement is indeed uncomfortable but this is more of a placement and dimensional issue. Was seeing how it would look like. The selector is the mini mp5 styled one above the trigger under the back sight and in front of the bolt. Was trying to remove the grip & thumb safeties and replace them with a selector switch instead.
I would like a thinner grip for sure, the 3D modeler had printed it quite thick, thicker than a Beretta, which is not what I was going for. The original video game pistol did have finger grooves, was seeing what it looked like without. And the lower end is thick as a design aesthetic only which is from the base video game pistol. I had done another version without the big bulk (see below) before but haven't decided on keeping it or not, does look a bit odd...
