Hey all! Want to pick your brain please. I bought a S&W .45 Shield and its shooting about 3 inches left. I tried to drift the front sight with a punch but it simply won't budge. Just ordered the MKIII sight pusher and wanted to see if there is anything special I need to know about this process. I've never had an issue with sights thus far. Will I even be able to move that front sight to the left WITH this tool? I don't wanna break the sight somehow by applying too much pressure. Anyway, gonna give it a go.
