Do you have any problems with this staying attached to the magnet when driving over bumps? Not getting air but just rough roads either paved or not. And is there something that keeps the glock and magnet from rubbing each other? I don't really care to have a nasty magnet mark on mine.
I've driven through my office's parking lot at speed over the 4" speed bumps and the pistol stayed in place...
As for the "magnet marks"... right now, the magnet is still in the bag and stuffed into that little square hole...
I can easily remove the magnet right now and have to be careful removing the pistol so I don't pull the magnet out too...
When you put the magnet in the slot, you need to keep the magnet surface as close the plastic as you can to keep the magnetism strength strong to hold the pistol...
I haven't done it "yet"... but here is what I "plan" to do:
The magnet is clearly more thin than that slot... I was going to get a small piece of carpet or wood (maybe a wooden paint stick?) then use a piece of road-bicycle tire scrap to put over the magnet/wood-carpet-whatever... just enough to make the whole thing a little thicker so that it has some active resistance/retention to moving around in that square slot....
The wood/carpet/whatever side goes against the armrest side and then the other side (with only the thickness of the inner tube) goes against the downward side plastic to engage the metal slide.
I might even use black electrician's tape to hold it together...
Regardless, the magnet makes no contact with the slide as the slide only touches the black plastic mold of that squarish box.
The magnet is rated to have like a 70 lbs magnetic-stickyness (or whatever the term is called)... but it can decrease rapidly as the distance is increased between the magnet and the steel... when its inside the plastic bag, and given the thickness of the injected moulding underneath the armrest hole is perhaps 1.something mm thick... it seems to have about a 12 lbs. magnetic stickyness... enough to keep the pistol in place.
