The one on my profile page is first generation and the one you are showing is second generation.
The Mateba is a great investment. If you decide to buy one you have to make the decision whether you want to actually shoot it or leave it unfired for collector status.
The first one I bought was around 600 dollars and I did consider it a shooter. It worked great for about three boxes of ammo and then the linkage disengaged. It was an easy fix but it was disappointing.
The next one I bought was a second generation with the shorter barrel shoud and wrench style barrel nut. It had a problem where the cylinder didn’t lock after hand cycling. The third I bought was back to the first generation. It too had a problem on deliver. It had a very small sear spring that was easily fixed.
The upside of these guns are very good investment possibilities, bragging rights for an unusual design even some gun writers have never heard of. Numbers of the guns are still less than 2000. The bad side is wishing they worked a little better and parts were easier to get if and when it has a problem. A scope mount is more than a hundred dollars from less than forty.
If you had the money, I would buy as many as you could be comfortable with and then use one as a shooter for those special occasions. Shooting one of these is a very strange experience.
I understand that the recoil is considerably reduced and I though a small barrel with a hefty load would be an effective close quarter weapon. Sorry to hear about the reliability issues
