How does one go about staking the hammer strut pin on a 1911? What tools are used and how?
I use a small center-punch & hammer, or a spring-loaded center-punch with the hammer laying flat on a steel bench block.
All it takes is a very light demple on each side.
Don't overdo it!
Afterword, stone off any metal thrown up by the dents so the hammer sides are smooth again.
PS: Don't overdo it!
