Just bought a glock 22 hi-cap 15 round mag, .40 s$w, will be doing a conversion to 9 mm in the near future, anyone have an idea if the glock 19, 17 round clip will work?
Longer mags, in the same cal. will work in like cals in Glocks, that's the sweet part.
You cant swap barrells and not swap mags.......(Like lone wolf barrell and change a 40 to a 9, you must swap mags as well.)
I did here that there is a retention probrlem going from gen 3 mags into gen 4 guns, I heard this from a Glock armourer, but I haven't experienced it first hand.
The G22 can take a 9mm barrel, which you already know. Fill the .40 mag with 9mm and rock and roll. It works. Many, many accounts of it working fine. Do a google search.
As for gen4 guns, I'm not sure. I've seen it work with the first 3 just fine.
