Some recent additions to my rotation:
With Deadly Force- Episodes are pretty infrequent but worth seeking out. Scott Reitz needs no introduction and his guests are very, very useful to listen to, especially if you are interested in the roots of what we do now. The episode on movie gun safety, with two actual film company armorers is pure gold.
That Weems Guy- Lee Weems is a long-time cop, trainer and cohort of a bunch of smart people in the business. He has great guests and lots of very good discussions on guns, training, and how we got to where we are. He's been doing a deep dive on the Modern Technique of the Pistol and the history of the people who developed it.
