Once a year I like to do some sort of firearm training. Last year I took a pistol class at the Bullet Hole in Belleville, NJ. Excellent trainer and a great group of guys. This year I would like to take a shotgun defense class. I have spent most of my shooting time this year shooting skeet so I would like to take a shotgun class. Can anyone recommend a course/trainer in the NNJ/PA area. Thanks.
