I finally got the parts to replace my 18-2 sight blade. My question is after you tighten the nut and screw do you back off the nut a 1/4 turn before you stake the screw or do you leave it tight and then stake it with a set punch?

Back it off 1/8-1/4 turn then stake

I need higher rear sight blades for the S&W rear sight. Where did you get the blades and how long did it take to get them?

Thank you.
