pretty much if you are sworn le or peace officer with arrest powers you are exempt from a whole lot of nys gun laws. we will start with magazine capacity( peon=10rds le= no limits), suppressors(peon=no chance buddy/ le= how many tax stamps can you afford?) sbr's, sbs's, even pre 86 machine guns can be owned, just need to inform the local sheriff. yet another way that ny makes sure that people on both the right and the left distrust le.
