I haven't kept up with all the laws recently, and I know this is relatively short notice (~4 hours), but there's (what appears to me to be) a MA-compliant glock 21 on gunbroker if anyone's interested. Currently at $415 with 1 hi-cap mag, 98%, plastic sites. http://www.gunbroker.com/auction/ViewItem.asp?Item=6822959 Of course, verify MA-compliance yourself. I offer no advice as to such with this post. Happy hunting.
