removing pretravel reduces trigger pull weight?

So I have been playing around with removing pretravel by putting plastic spacers in the ejector housing ahead of the trigger bar and apparently it reduces trigger pull weight by about half a pound to 3/4 lbs. It seems to drop the stock 5lb firing spring to 3lbs of pull (use to be 3.5lbs) and the 4lb firing spring to 2.25 lbs of trigger pull (use to be 3lbs). These were all measured from the middle of the trigger with a trigger scale. Other mods are zev v4 connector and comp spring kit with a nice true mirror polish on all surfaces as well as the marine firing spring cups. Can't figure out why it reduces trigger pull weight but it does. This little mod dissables the trigger and drop safety but the firing pin safety is still fine and because this is just a range/target gun/experimental gun that is fine with me. I can get the trigger safety back if I wanted with shaving down the rear of the trigger safety but I don't see that I really need it. The sear is still fully covered by the firing pin so I don't think it will go full auto but I'll just be load 2 rounds at a time for testing. I also put a setscrew to take out overtravel which is nice. Either way I have another ejector housing which is stock which I will put back after I'm done playing/testing with it. Right now it has a total trigger travel of about 3/16 inch. I could probally get it down to a total trigger travel of 1/8 or less but I like the sear being fully covered by the firing pin nub (I have read 3/4 only needs to be covered for it to be safe). Either way, I love the way it feels right now.

The drop and trigger safeties are there for a reason. The trigger safety is also there for reasons beyond just pulling the trigger inadvertantly. Here is some info from The Glock In Competition.

PROTECT YOUR TRIGGER SAFETY
Removing the trigger safety is a common tactic, but DO NOT let someone do that to your gun. The trigger safety doesn't act as a safety in the conventional sense. Sure, it helps prevent accidental depression of the trigger from the side, but its real function is to serve as a kind of backwards drop safety. The drop safety you see inside the slide works to prevent the striker from falling forward and setting a round off when the gun is dropped on its nose. The trigger safety works to keep the gun from discharging when dropped on its backside, muzzle-up. According to Armando Valdes, world-renowned Glock jockey

Chapter 1-1
Triggers, Triggers,
Triggers

and armorer for Miami P.D., the trigger safety first came about after Glock did tests involving dropping the gun out of an airplane. When dropped from a height, the weight of the trigger mechanism was enough to pull the trigger to the rear and discharge the gun should the gun land muzzle up - even if the gun has a standard connector installed. In any shooting situation there is a risk that someone will drop a loaded gun. If all the Glock's safeties are working, that's not really anything to worry about, but if that gun has had the safeties deactivated, and that person is using a sexy low-travel, low-poundage trigger system they cooked up in their garage, look out.

The Zev v4 connector lightens the trigger pull but adds a fair bit of pre-travel... Glockworx makes a trigger with a small pad to get rid of some of the pre-travel just for that reason... Very similar concept to what you are doing with the pads...

Not sure what you mean by disabling the drop safety... If your pads pushed the cruciform back so far that they are sliding down the ramps, that is too far. I'd also make dang sure the striker safety is working, too... You can check it by looking through the magwell as you pull the trigger... Unloaded of course...

Have fun, but be careful...
