Specs on some of these newer models claim you can set the trigger pull down to 5 GRAMS !......
I can come close to that with a 1960's era Hammerli, but when I did it started putting shots into the ground because you are at the point where the weight of the trigger's fingerpiece can set it off. Then too, I have my limits...
It's interesting that the cost of a Freedom Arms revolver and some European free pistols come so close together.
The state-of-the-art free pistol is ideal for the competition it's designed for, but I'm not sure it's good for anything else. I think they take .22 LR accuracy to the highest level in a handguns though. Especially if the handgun is to be held in one hand.
When it comes to semi-automatic pistols you don't have to spend a lot of money in relative terms. Accuracy is dependent on the quality of the barrel and ammunition. Back in the 1960's I often saw .22 Ruger pistols shoot into about 5/8" @ 50 yards from a machine rest, after being rebarreled by our better 'smiths using premium barrel blanks (usually Douglas) and match chambers. At the time this was accomplished using Eley ammunition.
Concerning the cost of free pistols - I would look for an older used one, or one made in Russia or Czechoslovakia that offer excellent values for the money.
