The 10mm round is extremely versatile! It's worth the money, imo. You can have rounds down to being as weak as the .40 S&W (Short & Weak), and a round more powerful than the .357 Magnum! Even approaching the power of the .41 Magnum!
DT has 10mm ammo that penetrates far, and expands wide (1.2 inches!)!
You can easily use the 10mm for self defense DEPENDING ON the grain and load you buy / make (a lot of 10mm ammo is watered down on the market, except DT's 10mm, it's hot!). Then use the hot loads from DT for hunting, taking down medium, and I'm reading about Ted Nugent taking down large game in Africa with his Glock 20!
Now, when you can actually put such versatility to the test, you'll soon see why it costs just a bit more (come on, not that much, like at Georgia-Arms.com... $13.70 for 50) to buy.
You can always start reloading, but make sure you buy an aftermarket barrel, since Glock barrels don't like lead bullets flying through them compared to others. Buy a 6" barrel for hunting long range, too!
I've asked around, and though I know it'll be a chore, it's not impossible: The Glock 20 is concealable! Just got to get the right holster, and clothes to fit.
I'm willing to make the sacrifice! For 16 (15+1) rounds of 10mm in the Glock 20? How could I resist!
If only glock came out with a compact frame for the 10
I agree. I think GLOCK should've made a Compact 10mm first, and then Sub Compact (G29) later on. The current Sub Compact G29 is roughly as long as the Compact G23, G19, G32, etc., but it has a shorter grip; if they just lengthened it about 1/2 an inch to fit a few more bullets in (so it could carry maybe 3 more), I think it'd be more attactive than it is now. Though, I'm still buying the G29 after my G20, anyway. I always like backup, even if it has but 11 round (10 in magazine, 1 in chamber) capacity.
