It was quite a bit of $$, and you have to bring a considerable amount of ammo with you, but it was a great mix of classroom, range training. There were 10 LEO from Manchester, NH (Glocks, S&W M&P mix), my P226, and an Air Marshall with his P229. The range course they had was a simulation High School scenario, with 3-4 man teams. We had to sweep a two hallways, clearing classrooms, slicing pie.....etc. I would definitely recommend it, and you are more than qualified to get in. Now it's an "expert level" course, but the GB name carries enough weight behind it 😉 And no, no brand name brainwashing. I'm pretty sure that your G.P would be fine. There was no suggested manufacturers when I took it.
