The Springfield Armory Echelon 4.5F Comp Gear PAC is a new, full-size striker-fired polymer pistol in 9mm. It has a 4.5-inch barrel with an integral compensator, a Viridian RFX 11 green dot optic, ambidextrous controls, an accessory rail and a Melonite finish. Three 17-round magazines and one 20-round magazine come in the box. The listing photo is a stock image.

This configuration suits range work and home defense, and the optic and rail add to that setup for a buyer who wants a ready-to-run pistol. Some states add permits, waiting periods or magazine limits, so check local rules before you order. A buyer must be 21 or older to take a handgun home from a dealer. The 17-round and 20-round magazines give the buyer capacity options at the range.
