i own a mini 30 and it has been my g-to gun for the longest of all my firearms. its reliable, fairly easy to dissasemble and clean, shoots anything i feed it, light enough to pack all day and a great bush/camp gun when needed. i have a 581 model in factory condition for the longest time and now upgraded it to the sparta stock which is nice.
as for reliability it has never malfuntioned on me with good ammo, i had one case of junky surplus that i had issues with, but now there offering a 6.8spc cartridge for it and i think that would make an excellent all around use cartridge,
ive takin mine everywhere, backs of quads, horseback, dropped it in rivers, puddles, brush, dirt and everything in between and it fired
just my 2 cents
