Glock 20 shooters

[Dark Mod]

I have a Lonewolf .40 conversion barrel that works perfect in my G20s. However, just for kicks last week at the range I ran 100 rounds of .40 thru my Glock 20 with the 10MM barrel installed (stock barrel).

I shot about 45 rounds (3 mags full) of .40 and since it was just .40 white-box-range-ammo, not much recoil. Functioned perfectly. Then I ran some normal 10MM thru...slightly more recoil but honestly, most commercial 10MM is still kind of weak.

Then I loaded up my Glock 20 magazines with one round of 10MM and one round of .40, stacking them every-other-round like that until full. Ran 6 mags like that. No problems, functioned 100%. On one mag I did run some of my 10MM hot reloads (135 Grain Noslers with 11.4 grains of AA#5 for about 1500 FPS) it was freaky hearing and feeling a CRACK/FLASH with the 135 grainers and a small PUFF/POP with the .40 whitebox. hehe..

Stock 17 pound recoil spring the entire time.

Knowing that the 10MM/,40 round seats on the case mouth I was concerned at first about a .40 round getting 'captured' by the extractor on the G20. Then I figured out that in cycling, the round comes up from the bottom of the breach face and hooks itself behind the extractor.

Interesting day........

But it is nice to know that in a pinch, you can run .40 in a stock G20 platform.

I gotta try that!!!! i dont think it would be too dangerous since the round will sit back in the chamber a bit. Kinda like firing a 38 spl out of a .357 revolver. I had no idea you could pull this off
