New member in Mass *ugh* but an old Marine shooter, these laws are a tad squirrelly. I was looking to get an HK 45 which is Mass compliant huzzah, but was also looking at the USP in 45, which doesnt look like its on the list, yet other calibers are. Also apparently newer glocks are LEO only yet they are on the "approved" list.... gaaah no wonder why people here just buy baseball bats. My main question though is about the USP .45 as it is the same pistol basically but a couple hundred dollars cheaper
