Got an echelon 4.0c. Only 100 rounds through it. 2 frames. The original is a small the one on it is a large. Not in length but in width. Comes with a TLR7 HLX, and a red dot. Not the one that’s on it. The one on it I’m reviewing for a company. I’m a Glock guy. I was trying something new but I just can’t get my hands to like it.
