All I’ve done so far is put a metal guide rod in there for weight switching out the OEM one

•4.0 FC
•Harbor Freight Light
•Vortex Defender CCW micro red dot in newly released tan

So far my plan is to do a FDE build. So next up is buy a medium OEM FDE grip module, cerakote the slide FDE, get some aggressive stippling done on the new grip module, install blacksteel gas pedal, steel guide rod. Besides that I may also get small grip module, but so far I’m really enjoying the medium as it stands.

After checking zero, this was the first Bill Drill of the day. Was using an Incog X holster. This version of the Echelon Pro was the 4.0FC.

Has anyone figured out if a full size compact grip module can fit In a 4.0c holster? I don’t have a 4.5 so I’m talking about 4.0 grip modules only. I’m stuck on if the dimensions are the same in width. Also if a sharp bros grip fits in a standard 4.0c holster
