Wheeler Sight Tool
Invest in a sight pusher... It'll save you time, money, and/or frustration... I use the Wheeler Sight tool. It's well made, and easy to use. I've changed out the sights in my M&P 2.0 Compact, Shield 45, and Walther PPS M2 so far. Took a little longer when I first used it for my 2.0, but the last two times I changed the sights out in under 10 minutes. It only took me that long because I took time to mske sure the alignment was right...
Another reason I purchased it is because I didn't want to ding up the old and new sight as well as the gun by accident while banging it in. I also wanted to install the Apex trigger on both my M&Ps, and that also requires that the rear sight be removed.... Lastly, I usually take the pusher with me to the range after installation, and I can make adjustments on my own if the sights are still off...
I was hesitant because I didn't want to spend the money, but in hindsight, it's worth every penny...
