Neat little guns. I'm becoming a real .410 addict. I've hunted nothing but my .410's this season for quail and the openner in SoDak, I used a M42 .410 for pheasant to great success. The only occasion I've used a larger gauge this year was day 2 and 3 in SoDak when I used a 20g.
Here's one of mine that is a favorite. I've thought of selling it to fund other .410's, but I'm still on the fence.
