A tiny bending of the main spring's sear finger can also prevent sear bounce. The end result is just a tiny increase in trigger pull weight. I would not recommend a DIY fix to a new firearm, especially when the manufacturer has issued a recall, but for those with 1911's out of warranty or those of us who did the DIY build thing, it's an easy thing to do. I'm still not a fan of really light pulls on 1911's, I prefer 4.5 pounds and a very crisp, glass smooth pull on my target grade 1911's and around 5.5-6.0 pounds for one that is intended for serious purposes.
