Bushings & screws on a 1911 frame.....
The trick of course is not to over tighten the grip screws on a 1911. Of the few dozen examples I've owned over the years I have had to replace many bushings as they came out when trying to remove over tightened grip screws.
While a staking tool is a nice option and of course a way to totally secure a replacement bushing I've never used one myself. I have replaced many bushings and just snugged them on with an appropriate screw driver. I've never had an issue with any that I've replaced over the years and I don't over tighten the grip screws myself.
