No knows for certain who first coined the phrase “Beware the man who only has one gun. He probably knows how to use it!” However there a lot of wisdom in those two sentences that the average individual would do well to learn. As rob Pincus explains in this video, When choosing firearms to protect you and your loved ones having them all work in the same way makes it easier for everyone to operate them under stress. An example of this would be a husband and wife who both carry and shoot Glock 19s, have his and hers Remington 870s and his and hers AR-15s for protection. If the absolute worst happened and one were incapacitated and the other needed a working firearm they could grab their spouse’s and be able to use it as if it were theirs.
My own efforts in this regard have not been entirely successful, but I think I’m pretty close. When I was younger and owned fewer firearms this was easy to do. I either had a 1911 pistol or a S&W revolver for a sidearm, my shotgun was a simple Winchester pump action and my rifle a surplus SAFN chambered in a round well suited to the desert terrain I lived in. Today things are more complicated because as a firearms enthusiast I have a variety of firearms that all work differently. Thankfully, I don’t HAVE to employ them all in a defensive role. Instead I employ a Glock and/or Kahr pistol and an AR-15. Even this combination has an issue though as the preferred method for chambering a round in a Glock is to slingshot the slide, while Kahr recommends using the slide lock to release the slide to chamber a round.
Many instructors, notably Rob Pincus and Clint Smith advocate the slingshot method for loading a firearm. This approach makes sense as it is a gross motor skill that utilizes stronger muscled in the upper body making it desirable for those without much upper body strength. It also creates a consistency as not every gun has the slide stop (if it has one) in the same place but all will release the slide if there is no empty magazine to push the slide stop into position. If you have a gun that doesn’t lock back the slingshot method will still charge the gun. Kahr’s recommendations meant I would either have to get used to using two different methods to reload my pistols or I could do something to ensure consistency. I’ll tell you what I did next time.
