This channel was one of my first intros into researching handguns on YouTube.

The channel is run by an FFL dealer in Minnesota. His videos are very well done and pretty thorough. He not only field strips the weapon, but tells you the pain in the behind features of the firearms he reviews.

Also, the guy who runs the channel is very active in his state legislature trying to fight back gun-grabbing or gun-restricting legislation. He's pretty fast with responses as well.
