Things I liked: These work excellent in half my guns and are the best for those guns. I use the .450 size for my HW's. They are extremely accurate in my HW97 & HW30S.
Things I would have changed: Make a .451 version.
What others should know: The .452 are too big and fit way too big in my HW's.
Things I liked: Solid mount. Probably the best holding springer mount made. This thing really bites down hard and holds excellent. Eliminates the mount from the POI moving equation. My D7 had exactly the advertised loop compensation.
Things I would have changed: Nothing
What others should know: The mount can be tight going onto the dovetail. You can use a screw in one of the blank holes to widen the mount so it slips on the dovetail. It will then have extra clamping power when you remove the screw.
Things I liked: It is a good basic soft case with nothing outstanding about it. They padding is quite thin and it will fold easily. Not bad for a cheapie at this price. The large pocket comes in real handy. Length was right on specifications.
Things I would have changed: Increase padding quite a bit.
