I notice that too and admit I got a kick out it.
Judaism is a religion, Israel is a country. Not all Jews are Israeli. Not all Israelis are Jews.
I have seen some pretty worn Israeli guns, especially the Kareen/FEG hi powers that came out of Israel had some pretty worn finishes. Of course, any gun that has done duty in the Negev (desert in the south of Israel) is going to be exposed to sand which is very abrasive and plays hell with finishes, so that might explain some of the finish wear.
I only have one Israeli gun. A 1937 Mauser that was rechambered to 7.62 NATO and restamped with the tzadi, and a Magen David- Star of David. The stock is in decent condition, but the metal is quite good.
