LB from GLOCK is not high up in the company but the after action report that he delivers to the big wigs about his time spent on the range with the legislators will speak volumes.
LB may not have an exceptionally high rank, but I can assure you he is highly connected. There are a small number of people who service Glock in the Northeast who are actually Glock employees - LB is the commercial sales manager. He works VERY closely with Glock's chief trainer, and the fact that he was selected without a LEO or Military background for a sales position speaks volumes about the regard in which he is held.
Glock's chief legal counsel sent LB out to the EOPS target gun hearings (which resulted in no changes to the proposed regulations that hurt us but, fortunately, also resulted in none of the changes requested by the AG's office), and was one of only two manufacturers to do so (the other being a small niche firm - Glock was the only one of the "top 10" manufacgturers at that meeting)
There is no amount of "retesting" that would qualify a Glock. The AG retains the full power to unilaterally declare a gun "Unsafe, non compliant, all dealers will pay a $5K penalty per gun sold or prepare for trial in a MA courtroom." If you think that is a bluff, look at the case where firms selling BB guns via mail order got whacked with over $70K in judgments in a MA court. In some cases, it's like the ancient Ruggerio v. Roach case where a Boston cabbie asked "how much money is a large sum" when appealing his denial of an unrestricted LTC - the answer the commissioner Roach gave was the he "was not prepared to answer" (as in "it's always going to be some figure larger than whatever you prove you carry"). Similarly, there is the very real risk that no matter what Glock does, the AG will "just happen" to conclude the "didn't quite make the cut" on the safety issue.
Glock went to great lengths for MA, including several design changes for compliance - some obvious; some not.
Even after all this, Glock sent LB to the GOAL event, and their rep continues to keep in contact with MA shops despite the inability to sell new guns behind enemy lines.
