I’m sure they’re a terrific gun, but I probably wouldn’t own one. If it ever hits the fan, where are you gonna easily find 10mm ammo? Just get a .45ACP, or maybe a .40, though .40 probably won’t be EASILY found, but it would surely be easier than 10mm.
Having said all of that, if you already have a good variety of firearms and are well stocked in ammo, I’m sure the Glock 20 is a terrific choice for your application of it.
Happy shooting, and stay safe out there! :)
I'm not sure of the right answer on this. Is it better to have weapons in a broad range of calibers so any ammo you find can be used, or is it better to specialize in a small number of calibers so that you can store/reload the few you might need? I went with a variant of your choice - 12 ga, .45, 9mm, .223, and .22 LR. Whether getting just a few calibers is right depends on why ammo becomes scarce, and I've always been terrible at predicting future trends.
youcaneasily get 10mm at cheaper than dirt. from a bunch of different makers.
I shoot and reload. I’m set for 45 and even carried a SW 625 loaded with hard cast 45 super as a trail gun up until now.
This is a little lighter and was an excuse to play with a new caliber. I’ll reload for it so ammo isn’t a problem. Other than brass, component are easy to find. I even found a pound of Blue Dot yesterday.
I’m thinking about getting a 40 S&W barrel for the gun just because I can get brass for free and not worry about chasing it down at the range.
Given the ammo shortages since Obama came to office, you won't find ANY ammo.
Basic common sense: keep enough ammo around for each caliber of gun you may need in SHTF. A thousand rounds seems right. With that much, in a SHTF situation, you will more likely run out of luck before you run out of ammo.
