My EDC for 10 yrs has been a 6p original round.Recently I put a Malkoff M60 in it and could not be happier. That said my primary stash is running low and I have been thinking of going to Battery Station rcr123a rechargeables or boring the original 6p body to fit a 18650 protected rechargeable. Also I may have to spring for a Malkoff M60 MC-E later so I need a direction to go.I have a identical 6p as a spare and a backup light so its a double down affair.Please offer me some wisdom as I,m a newbie. Thanks
