I've got one of those Swiss magazines. I bought a byf 42 back in 79 and it didn't shoot reliably. I read an article by Michael Reese III that recommended the Swiss mag to improve reliability. He was right. It certainly improve the gun. I hope you have a loading tool, if you intend to shoot the gun. Using your thumb on the button to pull it down gets old very fast. My Swiss mag looks just like yours...
