Do you have any other caliber for the 12 ga ?
What are these made of? Will it hold up to sustain use or is it a limited life span (like 5 shots)?
Lol why tho? 410 is more expensive lol.
12 gauge to .45 ACP would be awesome. I'd pay an arm and a leg for one of those if you could get them in.
Haven't heard of calibre conversion kits before? They allow you to use low pressure cartridges (generally shotgun and pistol) in an emergency. You can buy kits with a dozen conversions that will fit in a 12ga.
