Expected it to work better, broke tip of front sight - Wheeler Engineering Fine Gunsmith Equipment Armorer's Handgun Sight Tool

Bought it to change out the factory sights on my Springfield XDM to TruGlo TFX Pro Sights. During rear sight removal I noticed the sight block on the tool would twist and didn't keep flat pressure on the sight, it took a lot of force to get out as it only applies pressure to the top of the sight and not pushing in the dove tail. While trying to remove the front sight it broke the top of the sight off and I ended up having to drift the remaining part of the sight out. I did have to prestart the new sights before pressing them in, no issues after that. I did have some marring on the slide after it was finished. The tool does work to a point, but I would like to see some sort of dovetail attachment to provide a more even pressure.
