Wal now I realize that what I prefer the rest of the world seems not to, but since you asked:
Magnabrake finished at 8.5"
Just can't see the need for a brake. No way I'd do that and I'd want the barrel no longer than 7.5"
satin honed finish
Really dunno what this option is but to me the finish on the FA Field grade guns is precisely what a hunting gun should have. I'd not change it.
action job
Perhaps it's just becuz all the ones I've handled had a factory action job but I've yet to see an FA trigger I'd even think of messing with. Ya can't improve on perfection.
cylinder stripes
Strictly cosmetic. Iffen ya like em go for em.
numbered cylinder holes
Finally an option I actually like and would definite recommend. Dunno why FA doesn't do it already.
jeweled hammer and trigger
Again strictly cosmetic. If you like it go for it. Does look nice.
three ring scope mount
For sure if you're going to scope it go for one. I consider the T'SOB the best but am aware of none for the FA guns that isn't a good one. Me I'd use factory irons.
slings swivels with a nylon sling
Not on a bet. When you're actually hunting the gun belongs in your hand. When not a shoulder holster is the way to carry if it has a long barrel and on the hip either strong side or cross draw if the barrel is shorter. Personally I'd not own a gun set up for a sling if not a rifle.
The FA Field grade guns come with those UGLY Pachmayr grips. No way I'd own that set up. Get a nice set of grips like the ones on the Premier whether from FA or MagnaPort.
