Dump the mini 14,....hard to find good mags, not a lot of people have them. When it breaks, you have to send it to Ruger to get it fixed because nobody sells part kits for it.
I am going with either a AR15 type or a good AK...
The 45 is a good pick,I am going with my 92fs and four spare mags.
You can pick-up a AK 74 and two thousand rounds of ammo for just over $600.00. AK 74 is reliable, light and can easily be used by anyone because of its low recoil rounds.
