"...can/should order a .357Sig barrel and mag for my Glock 20..." Don't know about 'should', but you can. Buying as much brass as you can afford at the same time makes the ammo's future issue go away. Able to shoot .41 AE out of my BHP for that reason.
The Long Wolf guys say it uses regular 10mm mags. Might need a different recoil spring. Nothing about springs on the Long Wolf site though.
