I can easily change both sights without a vice using my 120 dollar tool and 4 dollar in less than 15 minutes and I have several M&P's this is an easy to use tool that will not damage your sights or slide provided you follow the instructions of the tool.

Correctly re-installing the spring and cap to the striker block can be quite a chore especially if you don't have the right tools or experience, good luck with a punch with a $125 set of new sights like Tru Glo TFO's!
