I'm going to have to consider this for a bit QK, let it stir around in this mud I have left of a mind and I'll give you my opinion shortly.

What I'd expect is two-fold - the heavy slide absorbs recoil energy that would otherwise slam into the frame, your hand, whatever follows the path of least resistance. It's possible to make a gun so light you don't want to fire it. This might be the reason why.
The other reason is simple stress - the lightweight slide slamming home with no absorption could cause the thing to shatter or knife-edge its way off the mechanism. With no mass, it slams into a stop and shatters or flies and keeps going. Material strength doesn't overcome huge, massive stresses or repeated problems.
A thin, light slide if it blows is literally shrapnel in your hand.

I agree with rfurtkamp on this...the slide must have considerable "mass" to function properly...F=ma...There is a certain amount of Force required, and the slide is the easy way to get that force. Could increase the acceleration of the slide to make up for mass, but I believe that in order to do that, you'd have to use a much stronger "spring". I suspect that if you put in a spring that would make up the difference, you probably couldn't pull the slide back to chamber that first round.....my two coppers.

Also I have seen "race gun" 1911's with holes cut thru em to lighten em up, as well as holes cut in the front of the slide too. Too little weight and the recoil will be difficult to manage as well.

I believe there is an upper bound that limits recoil spring strength. There's only a certain amount of recoil energy available for a given chambering. This energy has to be able to overcome the recoil spring and move the slide rearward a sufficient amount to cycle the action. If you make the recoil spring too strong, it will interfere with the reliable operation of the action. You could even take it to the level of locking the gun up completely.
Also the mass of the slide is one of the things that regulates the speed of cycling. If you have a really light slide with a heavy spring, assuming that the energy available can move the slide sufficiently rearward, it's possible that the slide will cycle too quickly for reliable feeding.

If it isn't broke, why try to fix it?

What about the " Procilen(sp) G& made in Germany that goes though metal detectors and costs more than you make in month " lol howd they keep that one together

I think I read somewhere that in the case of a 1911, some parasitic drag is needed as the bullet is out of the bbl before it cycles and if that is not the case the 1911 pulse can be hampered with too light a frame/not enough parasitic drag.

I've worked as a machinist for a long time, before turning to the Investigations Field. <besides, it's more fun than cuttin metal> The slide needs forward momentum, along with a negative push <expanding force> from the recoil spring, to help strip the round from the mag. the weight of the slide, made of hardened steel, or stainless with a hardened bolt face of rockwell 45 or greater isneede, along with the slide weight gives the Inertia movment needed to make this happen. I think if you tried Scandium, coupled with a Rockwell 45-55 for a bolt face, it just may work. Berrillium ir Titaiium may be possible as well, but I 'm not sure if I want to stand behind it fo rth efirst time.. Good question for that Myth Busters show...
