The Springfield Echelon continues its development with the 4.0C Comp version. It provides an integrated compensator for flatter shooting, and includes both 18-round and 15-round capacity magazines (if your state allows). The 4″ barrel is a popular choice, providing a nice compact platform for everyday carry.
My guess is that this pistol shoots flat. I would also suspect it could fit in holsters made for other Springfield Echelon pistols. However, I won’t know for sure until we get one in house to verify fitment.
