So I'm holding then gun and slowly pull back the hammer and it comes out just a little bit and makes a click and stays in this position until I either squeeze the trigger or pull the hammer all the way back. Is this normal and why?

half cock
not really a safety, but it kept the hammer from resting on the firing pin, in case you dropped the gun on the hammer, on old style 1911's.

Thats the half cock notch, a safety feature should the hammer fail or be released somehow unintentionally.

Your hammer should NOT drop onto the firing pin from the half cock notch with a pull of the trigger.

series 70 hammers on the half cock notch had a HOOK on the end.

series 80 hammers on the half cock notch had NO Hook on the end.

so on a 80 series gun if you cock the hammer back slighty to the half cock notch, you can RESET the hammer forward by pulling the trigger, the series 70 hammers you can not do this.

most likely the hook on the 70 series hammers was ground off in favor of the 80 series style, because to reset the hammer forward you hand to fully cock the hammer and then thumb it down while squeezing the trigger, which is an UN-SAFE thing to do on a loaded gun.
by pulling the trigger the on an 80 series the hammer would "click" forward, without enough force or momentum to strike the firing pin and fire the gun.

if you dont like the 80 series style then you should be able to put in a 70 series hammer without any problems, and (to my knowledge) it shouldnt affect the other 80 series FP safety mechanism.
