Good sight so far - Ameriglo Notch Serrated Rear Sight

I Got This For My PF940C (80% G19 Gen 3 Build), Because I Was Not Able To Rack The Slide Off My Belt With The Sights To That Came With The PSA Dagger Slide And I Wanted The Sights To Match My PF940SC (80% G26 Gen 3 Build). I Have Some I Dot Sights On An M&P M2.0, But Decided To Try A One Dot Sight System. So Far I Like The One Dot Sight System Better Than The 2 Dot Sight System. I Also Wanted To Replace The 3 Dot Sight System. The Sight Was Not Easy To Install. I Have Not Tested This Sight At The Yet, But When I Do; I Will Give An Updated Review.
