Apx trijicon hd night sight set - Trijicon Beretta APX HD Night Sight Set

Received these and was really excited to put them on my APX. Tapped out the old sights with ease and then cleaned the slide. Put these on by hand until it was time to use the sitepress. I had A really hard time so I decided to pull them off and start from scratch. Same thing happened so I went back to the packaging and made sure they were the correct sights. One last shot and the rear sight got a little more than halfway. I know it’s not supposed to be this hard as I’ve changed out sights multiple times. I decided to give the front sight a try and right after about halfway it broke off. I now have a broken front sight and a rear sight I’m afraid to take off as it will probably break as well.
