Don't think that there are any leagle hi-caps out there for 10mm. Could be wronge but pretty sure that 10mm came out after the ban. I know that you can get hi-cap mags for the EAA 10mm but they are not legal to import. They have mags for them that will hold, I think 15 rounds. You can also get a 6" barrel for the EAA so if you hunt so the Glock is not the only choice for that.
