I tried the trigger on a Model 317 when it first came out and it was really heavy.
Plus, since it’s lightweight and has both fixed sights and a really short barrel, I’d think accurate shooting would be a challenge.
Frankly, I don’t see the point of this pistol and if I were looking for something along these lines, I’d definitely go with the 317’s 3-inch version with its longer sight radius and adjustable sights. (Actually, I’d first look long and hard for a used S&W kit gun such as a Model 63 since IMHO they are much superior to the model 317.)
The 617 is a much nicer revolver to my mind, though a bit heavy with that barrel underlug. My understanding is the 6 shot version has a steel cylinder while the 10 shot version has an aluminum cylinder.
If I were going to get one of these, I’d go for the 10 shot version with the 4-inch barrel (the 6 inch just puts too much weight out front).
Even with the 4-inch barrel, the 617 is pretty heavy, but it looks like it’d be a lot of fun to shoot.
