Thought I'd post what I've done to my GSG 1911 in case others may want to do it.
First I put a STI tactical adjustable site on it. This has the novak dovetail. I had to take about 10 thou of the front to get it to slide in, but once done, works great.
Second was flat main spring housing. This one is a Springfield armoury, it is a direct replacement. If you are going to use the internals from the gsg (housing was empty) the pin that holds the mainspring in is different on the gsg. I like the flat one better and this also got rid of the magazine safety.
Third was a short STI trigger, this was a drop in replacement.
Two other things I did and please, all you safety nazis, if you don't like it just don't do it to your gun, I don't need your sky is falling lecture.
The gun has a series 80 style firing pin safety, I removed that. If you want to do it, the pin on the slide comes out left to right and has to go back in RIGHT to LEFT. It is larger on the right end.
I also disabled the grip safety and put on new grips I made. Don't know if I like them yet, may make a new set out of rosewood
After adjusting the sear spring the trigger feels the same as my STI edge which is just over 2lbs. I was also lucky as the trigger has zero creep and breaks like glass.
Out at the range this is such a fun gun. Shoots best with stingers, but to expensive. Next works great with minimags (hard to find) and winchesters super speed, will probably end up using these. Used bulk ammo, but had a few FTFeed, I think to the lower velocity.
Hope this helps any body else thinking about doing some mods to theirs.
