Should you carry a reload for your CCW revolver?

I tell students in my revolver classes that I consider carrying a reload for your small frame revolver to be an act of optimism.  How long does the average gunfight last?  There are variations, but three to five seconds is a pretty good estimate.  How long does it take to reload a small revolver with a speed loader?  With practice, most of you will be in the four to five second range.  

See the problem?

If you decide to remain optimistic, Caleb describes How to carry a reload for your CCW revolver and How to reload your small revolver.

 

 

Warning! Hurt Feelings Ahead, But The Truck Gun Idea is Asinine for Most Intended Purposes

If my memory holds, I believe that we have seen exactly ONE active killer stopped by a guy who retrieved a long gun from his car before engaging the killer.  Overall, it doesn’t make a lot of sense to carry a rifle in your car in most urban environments.  The ever-present risk of the gun being stolen outweighs any potential benefit the gun confers.

3 Reasons I don’t Like Backup Guns

 

I generally only link to articles that share advice on a topic about which the author and I generally agree.  I don’t agree with this article. 

Why post it?  Because the issues he mentioned should be part of your consideration when deciding when or if you need to carry a second gun.  As a dude who carried a second gun on my person every single police shift I worked for 25 years, I think I he overstates all of the negatives he describes.

With that said, I think most of you will be fine if you skip carrying a backup piece to the grocery store.  I don’t often carry a second gun on my person now that I’m retired, but some of you face different risks than I encounter now.  There are also some important advantages to carrying more than one gun.  Read Passing Off a Backup Gun.  Understand the issues involved and make your best decision.

Teaching civilians isn’t the same as teaching cops

“But when it comes to physical skills like firearms, defensive tactics and practical self-defense, too many cops assume their law enforcement knowledge automatically transfers to citizen defenders. It doesn’t.”

 

 

Quote to Ponder:

 

“Ask anyone how they got really good at what they do, and there is one answer they won’t tell you:… School.
They learned it on their own. Not because there was a test to pass, but because they were curious.”
