Unfortunately I don't own this pistol, and the only pictures I have are those you see here, taken from the auction website. I have never tried to buy anything from Argentina (or Brazil or Mexico), much as i would like to do so. (I suspect that any sort of gun coming into the UK from South America would spend a very long time with Border Force !)
I think the pistol would need to have an equivalent link on the other side otherwise the barrel would eventually twist the flimsy jaws.
Cheers,
John
