The Nazis undoubtedly had widespread support - probably passive more than active. It was probably not a majority of the population but simply one of the larger parties. Remeber, their electoral support was declining when Hindenbeurg handed ppower to Hitler. However, the issue of Jews having guns removed is a red herring. For a start, most Jews saw themselves as Germans first and Jews second - hardly a basis on which to organise armed resistance. The first real armed resistance of any real note did not happen until the Warsaw Ghetto uprising towards the end of the war - and by then the fate of the Third Reich had effectively been sealed. Armed uprising by the Jews was more likely wishful thinking on the part of the Nazis. Nothing would have given them a freer hand and more support for genocide from the general population. They were so desperate for "motives" to attack Jews, that they invented myths like the "Jewish" destruction of the Reichstag and the bullshit of the Horst Wessels "legend".
