What is the difference between an AR-45 and an AR-9?
An AR-45 is an AR-style pistol-caliber firearm chambered in .45 ACP, while an AR-9 is chambered in 9mm. The two platforms can differ in ammunition, magazine compatibility, bolt and barrel components, recoil characteristics, and overall configuration. .45 ACP generally uses heavier, larger-diameter projectiles, while 9mm offers a wider selection of common PCC ammunition. Individual AR-45 and AR-9 specifications vary by firearm configuration.
