To me it sounds like a real snare mic’d very closely, completely dry and dampened (treating the snare itself and hitting it softly). After that it’s probably been loaded into a sampler, maybe a little bit of down tuning, some filtering and maybe subtle pitch variations using an LFO.
Nice sound, reminds me of certain Air drum sounds. Like this for example - https://www.youtube.com/watch?v=AfX52BTLuyw
p.s. sampling is your friend
