I voted for the RA9TA ranger,because I couldn't vote twice,and I have seen the results of this load on people first hand.
In truth,any of the loads mentioned are fine.These days,it's difficult to find a BAD load among the top brands. Some people are hung up on bullet weight,some on velocity. I like all the loads. A few cases of the RA9TA,and RA9t on hand,as well as one case of 147HST.
The Gold Dot is also as good as it gets.I base my choices on price,availabilty,speed of delivery. Your particular weapon may like one load better than the other.If that's the case,that's the load to go with.
Mine don't seem to have a preference,but my 9's are all Glocks.
