Don't know when it was made, but I do know that 41's are very particular about what ammo they will shoot well and cycle the action. And no two will shoot the same ammo the same way.
You'll have to try as many brands of ammo as you can to find the one or two your nice new pistol likes. The price of said ammo means nothing either.
Mine won't shoot anything but Remington Target ammo and IVI Standard velocity(don't think you can get it). It becomes a jam-o-matic with anything else. Works fine with high velocity ammo(It won't harm the pistol either), but for target shooting, it won't cycle with any other ammo.
