rush out,...I already use them for my tanfoglio,...but I have a feeling the CZ shooters will probably start using them. They are good also for indoor shooting, as the rubber base pads protect the mag as it lands on the concrete.

It's been done before in the 1911 world. Don't shoot in indoor ranges, you'll find your mags tend to explode nicely when they fall at double the original possible speed.
Please explain.....3-4 feet neither item has time to reach terminal velocity and a heavier item will accelerate faster.
They both fall at exactly the same speed, but the heavier one has more impact energy.
High school physics. Gravity is a constant, so all objects will accelerate towards the ground at the same rate. The variable is surface area (air drag) which in this case is so small as to be unimportant.

When resistance of air is negligible (which is the case with falling magazines) both of them will accelerate with same rate of about 10 m/s in each second.
Final speed can be calculated by formula V=SQRT(2g*h), which is at average height of 5 ft would be about 5.5 meters per second.
Why the confused stare, drop two items, one being twice as heavy as the other, from the same height, and the heavier one is going to accelerate towards the floor faster......although in this particular case the speed is negligible (and definitely not doubled) as compared to the extra mass of the mag weight causing a harder impact with the concrete floor at an indoor range was what FV was referring to I believe.
So maybe I am wrong here, and am having troubles getting my head around it, but are you saying weight of two equally dimensioned objects has no bearing on the acceleration? So if I were to take a ping pong ball, and a equally sized and shaped chunk of lead, drop them from the same height at the same time they are going to hit the floor at the same time? Not trying to be a smart ass just trying to get the understanding right if I am wrong. I realize in the case of the mags its the mass that increases the impact forces and the difference in speed is likely very insiginificant and minute, but still can't see the speed being exactly the same.
I have no problems getting burned and eating crow(once), just would like to fully understand the concept.(to prevent twiceI think Galileo did this experiment about 400 years ago. Dropping 2 balls from the Tower of Pizza.
I think he was burned later too
)Quick search gives this article for example.
In your example ping-pong ball will drop slower because of air resistance, but in that article bowling and golf balls fall at same speed.
Rob was right about energy, but heavier base pad should be sturdier?
I think it got nothing to do with weight - flimsy mags do explode on impact of concrete floor, but it all boils down to quality.

Link? I can't seem to find anything at Global Village.
The base pad is indeed sturdier but the magazine tube isn't. The greater impact energy translates a more significant vibration vibration up through the tube, which will shorten it's life. Some of us who have been around for a few years have already experimented....tragically....with this. Trust me; save your money. Note that due to greater inertia, the heavier base pad will tend to resist the slight acceleration you get from the magazine spring when you hit the release button, so at first, it will actually exit the gun just a tiny bit slower.
In a vacuum, the ping pong ball and the lead weight will fall at the same rate. No air to displace the relatively light (for its cross-section) ping pong ball.
Having read the article and looked at the formula, I would be correct then. If you are weighting a mag but not changing its mass, the heavier mag will fall faster, both objects have to be identical when dividing weight by mass in order for them to fall at the same rate. The bowling ball and the golf ball have the same result when dividing weight by mass, am I correct or totally out to lunch? I see it as 2weight/1mass cannot equal 1 weight/1mass, what am I missing? (other than maybe not paying attention well enough in what physics I took in school) Sorry for the thread hijack, but want to fully understand this. I am also interested where the OP sourced this info and if infact we can use rubber base pads in production?
I'm afraid you did not pay much attention to physics in school. On the surface of the Earth wight=mass, they even have same units of measure (kg, pound, etc.) Hard to blame you though, as I find local school program lacking a loot in the area of science. But this is totally off-topic.
As for original topic - it looks to me that production division is struggling. I myself switched to Standard as of this year.
