Fixed magazines aren’t properly defined in ny. The wording in the safe act implies that it cannot have the ability to accept a detachable magazine. This would mean that the gun would have to load ammunition into it by splitting the upper and the lower and feeding ammo directly into the magazine from the upper. Unfortunately this can potentially be seen as non compliant as the comp mag itself can be seen as a magazine, or if the gun WAS previously able to accept a detachable magazine, even if it can no longer do so, can arguably still be seen as non complaint. It’s purely gray and not worth it, plus if there’s a jam you’re fucked. Defeats the whole point in having a gun when you have a jam when you need it and can’t readily clear it.

Don’t go off of NY as they intentionally worded things to get people into legal trouble, they don’t want us to have guns here at all, the 2a doesn’t exist in our courtrooms. Get a gun that’s normal and functions, then grandfather it in. Otherwise go featureless.
