Shortly after these appeared on the Lipseys website, I had my LGS place a 4 5/8" on a wish list. It came on Friday and I was able to get it to the range later in the day, and on Saturday as well. It proved to be very accurate using a variety of hand loads in .327 and .32 H&R. The only factory load I had was Federal AE 100gr .327 loads (these are all business and shot well). Two of my .327 loads and one .32 H&R load were superbly accurate, shooting one hole groups offhand at 30ft. And I don't mean cloverleafs! I'll post these later when I get to my notes.
The trigger is typical for a Ruger, a bit heavy with some creep.
As for fit and finish, mine is the spitting image of majorKAP's in
this thread. Grip fitment is very similar. Even the serial numbers are close.
When I picked mine up, the store had actually received two, both of which were nearly equals except the other had considerable cylinder endshake. My, barrel/cylinder gap measures .007 (spy material) for those that may care.
I have two issues with the Single Seven which I think are easily "fixed."
1) When firing max loads, my base pin occasionally jumps forward. So I may need to call Ruger and get a new one or just go aftermarket.
2) To facilitate loading and, more so, ejecting empties, this thing is crying out for a free-spin pawl! Whether loading or ejecting, the rotational distance from the time a chamber is fully visible in the window until the next click is very small. Of course once you rotate to the the click, you can't load or eject, and the cylinder will not reverse. Err! Loading isn't bad because as the cylinder is turned, a round can be started into the empty chamber as soon as it begins to appear in the window. Ejecting for me is a bit more frustrating. I think Ruger should have removed just a bit more material from the loading gate area. It wouldn't take much, maybe a few thousandths, and the chambers would index perfectly with the loading gate. I realize this would probably add to the cost of manufacturing, but I would pay to have that bit of refinement.
Overall I am thrilled, especially with the accuracy. I think the Single Seven and the .327 are a perfect combination. Three years ago I bought an early, new-in-box, 4 5/8" .32 H&R Single Six with adjustable sights. All was well until I found out the thing would not shoot worth a darn regardless of the load. I've held on to it with the idea of sending it out and having it converted to .327. I still may do that but for now I will enjoy the S7.
