I also prefer the 38 Spec, 2 1/2 inch, and it does the same thing, but I'm not going to worry about it. I don't intend to engage threats at long range. I only wish I had gotten the hammerless model, since I do all my shooting DA. The SA release is so heavy that if you stage the hammer in DA you get exactly the same thing. I think the experts today say that staging on DA is a mistake, because when the adrenaline is flowing you will over-stage, it will go off too soon and you will miss. Unfortunately, I spent my life shooting DA this way and I'm not going to change now.
Actually, going to a range and shooting a piece of paper is pretty pointless - fun but pointless. I go to the woods as often as I can and shoot a man sized target at about 15 feet without the sights - not from the hip, but pointed, not really aimed. With a little practice you can get pretty good. I think that's the only practice you really need with a gun of this type.
I loaded up just a few of what I call hot boys, a pretty hefty load of Unique under a 125 gr store-bought hard cast, and the 148 gr HBWC seated backwards and sticking out a bit. That would be the first one out the door. They both clocked just over 1000 fps. When I saw that I bumped up the 125 gr charge a bit, but I haven't clocked it yet and I might never. The number doesn't really matter and I hope I never shoot another one of either, because if I do, it's because it's showtime.
I have no idea how Ruger fixes the problem, but I have a hunch. I bet they bend the gun just a bit. Bend may not be the right word, but we know their philosophy - superb engineering and cheap production. I approve and I love their guns, but face it, they're a bunch of corner-cutters. Just a hunch.
