one can never have too much ammo, but you can always have not enough. 10 round mags have been known to fail more than 7 and 8round mags, I carry 2 extra 8 round Wilson mags and an 8 round Wilson mag in the gun with 1 in the pipe. My BUG has 7 round mag and I carry an extra 7 round for it. Note; I live in a small town out in the Boonies, we have Cayoties, Bears, Cougers etc. running around. It never hurts to have enough ammo if something attacks you.
I carry 7+1 in my 457 and 1 spare with 7 in it. I feel that is more than enough for me and mine. I do occasionally carry only the one mag, but not very often
