Hi Tom. Thanks for looking to LuckyGunner.com for your ammo needs. This is NOT the 9mm Largo round you need. Although they are both 9x23mm rounds, the pressure of the Winchester round would be very dangerous in your Largo Pistol. I am sorry, but right now we are out of stock on the ammo you need for your Star. Keep checking back. When we do get this in, you can stock up at our great price!
