Something to think about
The heavier the bullet, the longer it stays in the bore and the more pressure it generates.
I have heard (no experience on my own) that the 3" 1911's are almost lacking in enough barrel to get sufficient energy to rack the slide.
If I noticed that 165's or 180's were leaving me out of battery or not fully running the slide, I would increase bullet weight to get more pressure into the spring.
Take my 2 cents and get some change from it.
