A buddy of mine has one in .44mag, I thought it was great so he put me in touch with the importer for the UK, all he had left was one in .454, I went to get it and my gunsmith said don't bother as you can't get the spares anymore as Mateba has gone 'belly up'
This is a photo of the one I was offered and in all honesty I'm still interested. You can remove the front and rear stocks and use it as a big pistol as well
