What makes them worth it ....quality of materials and craftsmanship.
I ordered a Freedom Arms for my 60th birthday a few yrs ago ... 4 3/4" octagonal barrel, premier grade, large frame, 5 shot, with a full action job and trigger set at 3.25 lbs ...in .357 Mag. In my opinion, that gun is worth every penny I paid for it ( a shade over $ 3K - but that's not the point ...) ....its accurate, its very well made, it's a piece of craftsmanship. It is exactly what I wanted ! It has value to me at that price - because every time I shoot it / or touch it - I love it and I'm very happy to own and shoot it ! Mine is a couple of yrs old now ...and I've put close to 10,000 rds thru it ....and for what its worth, I'd buy it again / and I'm considering ordering a matching gun, same spec, in .44 mag or .45 Colt ...when my birthday rolls around again.../ not to show off or as an investment or anything, but because I really love their guns - and think I want another one !
Freedom Arms also excels in some calibers that are really suited for large single action revolvers....like the .454 Casull, 475 Linebaugh and 500 Wyoming Express...
You can spend way less on other guns ..in fact you can spend way less on a premium double action revolver in maybe the same caliber ( like a S&W model 27 in .357 mag - same as my Freedom Arms ) - and while I have some of them as well..../ the Freedom Arms is just something special to me.
Sure they are 3 or 4 times the cost of a Ruger, or Colt, etc single action ...but that's really not the issue. Value is relative ...most any of the single action revolvers are decent guns ...and while all of us may have our preferences ...they're all just bullet delivery systems...if the Ruger, Colt, etc meet your needs..... then maybe you don't want a Freedom Arms.
They're a gun built to a different standard - different level of craftsmanship. Its not about the price - its whether you think that level of craftsmanship is something you'd like to have in a gun. I'm at a point in my life... where a few very well made guns, are what I choose to shoot...but they aren't for everyone / but I hope in your life, you're as lucky as I am, to be able to buy special guns, if you want them.
There are lots of guns out there at or above $ 3,000 .... a number of 1911's from Wilson Combat, Nighthawk, Cabot, etc....the Sig Sauer X-Five L-1 model ( a single action only all stainless with an adjustable trigger in it)....and some of the other custom mfg's of single action revolvers of which Freedom Arms is just one ..... are they a good value, yes, I think most of them are. But you'll have to decide if any of them are right for you or not.
