EOPSS has little to do with the legality of Glock Sales here in the People's Republic of Massachusetts.
Most Glock models have been on the EOPSS roster for quite a while, the issue is the double secret nonexistent list that the AG is the final arbiter of under the guise of consumer protection.
The AG claims (and has claimed) that Glock handguns lack an effective loaded chamber indicator, despite the fact that the Glock indicator is nearly identical to several similar indicators that the AG has approved.
