Here's the difference between a single action and a double action pistol.
Little fuzzy on the difference between a single action and a double action pistol? This video does a great job at explaining the difference in detail.
After watching this video, if there was any confusion between the different pistols, you should be clear on them now. They give clear explanations, and describe everything very well. I found this to be very interesting, and learned a lot from it.
What's your preference on a home defense handgun? What about a carry pistol? We're listening!
