So has anybody bought a .40 barrel for a G20?   I'd guess the mags would work. Is there such an animal?  If so, function okay?

I've shot 40 out of my stock 29.4 several time with no issues.

LWD conversion barrel works perfectly. I'm thinking a 357 conversion might be best, I think the large 20 might tame that round well.

Is there a .357 sig barrel for the 20?   A big frame 10/.40 would be pretty badass.

I have the lone wolf conversion and shoots well , but shot 40 for years out of stock 10mm barrel in two glock 20's and a 29 with no issues either. Just be careful slamming home the mags with the slide locked back . 40 cal has some play in that mag and can pop out .

^this, I do the same without issue.

I think it was acquired when I purchased a used G29sf, which I later replaced with a G29.4..... I don't think I'd go out of the way for a .40 barrel unless you have another driving reason to shoot .40, I will say the G29sf/G29.4 with .40 conversion barrel with both fairly soft shooting compared to the dedicated .40 models of similar size.

Friend of mine got a KKM conversion barrel for his G20, and that thing was a tack driver when I shot it....

I am not a .40 fan, but it was pleasant to shoot in the large frame Glock...

LWD makes G20 conversion barrels for both 357 SIG and 9x25 Dillon
