Sheldon Silver: Microstamping Not Part Of Gun Package Talks – Supporters of a microstamping, which makes  guns and ammo more trackable, fear their best chance of getting the Mayor Bloomberg-backed measure enacted into law is slipping away.  A gun control package being negotiated between Gov. Cuomo and legislative leaders does not address microstamping—an issue Senate Republicans vehemently oppose despite its widespread support among law enforcement. “The Senate [Republicans] refuse to consider it,” said Assembly Democratic Speaker Sheldon Silver, whose house has passed a microstamping bill several times.
