You can define a frame of reference depending on your point of view, but it would normally be the Earth.
The frame of reference for a plane moving at 500 km/h can be either the ground or the surrounding air. In both cases, the speed of the plane relative to these frames of reference would be 500 km/h.
The frame of reference for a plane moving at 500 km/h is typically Earth's surface. This is because the speed of the plane is measured relative to the ground, which is considered at rest in this context.
The frame of reference for a plane moving at 500 km/h can be considered as the inside of the plane itself. This means that the speed and movement of objects inside the plane are relative to the plane's motion, while the ground outside may appear to be moving rapidly in the opposite direction.
The frame of reference for a plane moving 500 km could be the Earth's surface, the atmosphere, or the plane itself, depending on the context of the question. In most cases, the Earth's surface is used as the frame of reference for calculating distances and speeds of moving objects like planes.
Because motion only exists relative to something else. when measured from different reference frames, the same motion will appear to have different speeds, accelerations, and directions. And the thing of it is ... they'll all be correct !

Yes it does. That's the only way that motion makes sense. There's no such thing as "real" motion. It's always motion compared to something else. Have you ever read a book that you held in your hand while you sat in an airliner flying along over the ground at 400 or 500 miles per hour ? Referred to the ground, you were moving at 400 or 500 miles per hour, and so was the book. Referred to you, the book wasn't moving at all. Which motion was the "real" one ? Both of them were real, and neither one was more real than the other one.
Assuming you mean "inertial" frame of reference... it is any point of observation from which other objects appear to be still or in motion relative to you. For example... On an airplane flying at 35,000 feet. All the other passengers appear to you to be sitting in their seats or walking down the aisle at a leisurely pace... If you tossed a ball in the air, it would appear to go straight up and fall back into your hand... To someone on the ground, you and all your fellow passengers seem to be hurtling thru the sky at 500 mph. And the path the ball follows is not straight up or down. You and your fellow passengers share the same inertial frame of reference. In a similar sense, the earth under your feet appears to be still and all the objects seem to move or not move in relation to the still earth. In fact the earth is spinning... beyond that it is revolving around the sun, beyond that the entire solar system is moving in a galaxy that is, itself spinning, and the entire galaxy is also moving thru a universe that is expanding... Each of these are other inertial frames of reference. Einstein's theory of relativity states that none of these frames of reference is preferred... and that all observations, including those relating to time, dimension and speed, are entirely relative to one's inertial frame of reference. Thus different observers in different frames of reference perceive things differently. because even time varies with frame of reference, this renders such concepts as simultaneity specious. If time itself passes at different rates for different observers, then no two events can actually be said to happen at the same time.

The grip frame on the X-Frame series interchanges with current K-frame and L-frame guns. In other words, any wooden grip that would fit a current 686 will fit the .500 Magnum.
