Lenny,
First, welocme to the forum.
Second, yes, the laws are FUBAR.
Third, GOAL is doing what's possible. Laws are made by politicians, and politicians are made by votes, and votes are made by making the most people happy. Shooters are a minority in Mass, and the Nons and Antis will out-vote us, as a general rule. Expect no epiphanies from Bacon Hill, with the bottom line being, "Holy crap! We should not be so restrictive of rights! What were we thinking?" Change will be incremental, and driven by the individuals in the shooting community.
At the risk of sounding like a Kennedy: Ask not what can GOAL do for you, but what can you do for the shooting community. Find out from GOAL what the nasty proposed legislation is, and write and call to express your displeasure (or say, "vote for this" on stuff that benefits us). Take a non-shooter to the range, and, while there, try to explan the Mass gun laws. Be a responsible gun owner, and an ambassador from our community to society at large.
I know that this is not germaine to your original post WRT the Glock, but you
DID ask..... As for the "friendlieness".....you're in a club, and there are rules (both posted in stickies, and unwritten ones, that are learned by osmosis). You'll get it, but a thick-ish skin is often a benefit. There's a lot of knowledge rattling about, but sometimes, when a question has been beaten to death, one more iteration of it is too much.....that's why this exists:
