I don't know. President Bush said he'd sign the assault weapons ban if it passed Congress. Is he unacceptable? He won twice with huge conservative support both times.
Given the current Congress, I don't think any significant gun control laws will be passed. If they were, it would depend on what they were but I wouldn't automatically assume Rudy would sign it.
I don't think he'd be any worse than anybody else who might be in the WH.
He's a smart politician and if the base and the lobbyists(NRA) and a bunch of supporters in his own party are that opposed to a certain bill, I don't think he'd go against all of them and sign it. If a given bill has strong bipartisan support and no real significant opposition, he probably would sign it.
But as I said, gun control has largely disappeared from the federal agenda. The dems won't bring it up, and I doubt Rudy would make it a priority or even an issue. I think he's basically fine with the status quo on guns and wouldn't be that much different from the current administartion when it comes to guns.
Of course, I could be wrong, but that's just my feeling on it. If guns were a red line issue to me, I can see why Rudy wouldn't exactly be a strong choice, but I think fears of him taking away everyone's guns are overstated.
"Given the current Congress, I don't think any significant gun control laws will be passed."
Combine the political power of the NRA with the fact that 60 votes in the Senate are needed to pass anything and I agree with you. I don't recall hearing about gun control being on the Dems' agenda.
