I like the 317. I am not an expert but I will be happy to tell you what I know about mine. I had mine for about 4 years now. The trigger pull is heavy but it is not a target pistol.
I gave my grandson my S&W 63 and missed it. The 317 is not equal to that revolver. I bought a 3" for my son also, and a special edition LadySmith snub nose in the leatherette case, fancy wood grips, for my wife.
I love the lightweight. I can put my wife's gun in my pocket and forget it. But she won't let me keep it. On my 317, I replaced the grips with the wood j frame with a Tyler T Grip. I like the feel better. My son left his stock with the rubber and my wife liked the "spegels".
My pistol shot high and could not get enough adjustment in the rear sight to correct this problem.
I removed the sight and took a file and filed the frame enough to get the pistol to shoot POA. My son did not have this issue. My wife has fixed sights so it wasn't a issue either.
I like shooting .22's and owned a bunch, still do but gave most of them to my children and grandchildren.
So I have my model 18 and the 317 and think I am going to keep both for myself. I don't think the IL is a issue at all, and never had a problem with the IL on any of the 3 guns. Leave the lock alone and blast away.
Good shooting, have fun, that is what the .22 is for. [ended in a preposition....oh well]
