This is ridiculous. Seriously, you've ruined the sights you already purchased. If they were for your Glock they shouldn't have needed any trimming or fiddling with to go in, there's a tool for that.
You clearly don't have any idea what you're doing, the 'helllllllpp' you need is a proper gunsmith and at least a new rear sight.
Even if you get them to go in and stay in, there not going to last.. You're going to reach for your pistol one day and the sight(s) are going to be gone. You really should take it some where. There's zero shame in having it done right.
Rise and rise again, until lambs become lions....
Fear cuts deeper then the sword.
