Glock 23 -.40 cal to 9mm conversion in under 13 seconds by

In this video I am going to show you how to convert a Glock 23 .40 caliber handgun into a 9mm handgun with a simple barrel change. I am also going for a personal “world record” of the process. I do this in 12.96 seconds. It’s not really a world record, but I was just having some fun. You can buy 9mm barrels from or You can also find them on eBay or Amazon. Not all .40 calibers can be converted to 9mm, so make sure you research before you buy a new barrel. Also, keep in mind that you will want to purchase new 9mm magazines for your new rig. The .40 caliber magazines can hold 9mm ammunition, but I find that the gun tends to malfunction quite often, especially if you use cheap ammo like I do (hint hint to ammo sponsors). Once again, go ahead and spend the money on some new 9mm magazines. I bought mine from and am very happy with my purchase. You don’t want to be in a life or death gun fight and not have the best equipment to survive. Why did I do a conversion instead of just buying a separate 9mm handgun you ask??? Because another handgun would cost hundreds more! I feel like I have two handguns for the price of an extra barrel and some magazines (I spent about $150 total). Do you have any questions? Please feel free to leave a question in the comments and I will do my best to answer. Have an idea for a video? Leave that in the comments too. Thanks, Coach David Alexander (

Self Defense Shooter “Step Back Quick Draw”

In this video I am showing you how to step back and fire in an up close and personal self defense situation. If you have a gun (“tool”) readily available than you might as well use it. As long as you’re trained to fire a gun responsibly then you can multiply your self defense skills by using a “tool extender” such as a gun, knife or bat. Do not try to use a gun if you’re not trained! All you will be doing is supplying a bad buy with a gun! If you have any questions, please put them in the comments and I will do my best t answer.
