Spare Ammunition is a Must!
Hi. New to this forum, but not to carrying a firearm. For all you guys who have the "if X number of rounds isn't enough, then..." mindset, I want to point you in the direction of an experience that became very public. Back in 1997 an off-duty police officer was in a McDonalds in Barstow, CA when it was robbed. He subsequently wrote an after action report that was released to the public. The most pertinent aspect of that report was "ALWAYS carry extra ammo." You can find this report if you search; I'm not having any luck at the moment. In any case, the officer was armed with a subcompact Glock handgun. When he was confronted by the armed criminal and a shooting ensued, his handgun was emptied very quickly, and the full size magazine he carried as a spare became very important. This is really my point: If your armed intervention should turn into a two-way gunfight, you should not underestimate how quickly you may expend every round of ammo in whatever you're packing, even if it's a full size 9mm. We'd all like to think we could track rounds fired and hit our targets, but that doesn't always happen and if it doesn't, you should anticipate the need to reload your firearm.
With that said, I no longer use any revolvers, but when I did, I found speed strips to be simply too slow. With a great deal of practice, transitioning the revolver to the off hand to dump the brass while reloading with the strong hand, I was able to get very quick with speed loaders. It's still a lot of fine motor skill and digital manipulation, and it's hard to say if I could have been so efficient in an actual crisis. Fortunately I never found out, but I recommend making room for speed loaders.
Lastly, if worse comes to worse, any gun is better than no gun. This is just a subject where it seems prudent to tip the odds in our favor.
