It's hard to make suggestions not knowing what your repressive state considers Massachusetts complient? Pre 98 Glocks vs. non-complient post 98 Glocks? That makes a tremendous amount of sense? Who makes the decision to consider what's complient vs. not complient? Legislature, police chief, governor, King, panel, board, dictator, mayor, firearm experts? Don't let your govenment fool you this non-complience garbage is an attempt to disarm law abiding citizens of their rights. They, who ever they are? are taking reasonable restrictions as far as possible. It places a burden on gun manufactures as well. I don't know whether or not you can even buy ammo over the internet and have it shipped to your door?
