I replaced the commonly known POS Glocks stock sights (on the G43) with Ameriglo Spartan Sights. The G43 is now on par with my Shield (which has Ameriglo Hackathorn sights). I really like Ameriglo sights and have them on several firearms. You can not go wrong with Ameriglo and they have numerous combinations for your firearms. Testing can now continue on the G43 vs. Shield Article. The G43 was at a huge disadvantage during my first few range sessions, as the Shield had an advantage with better sights. I have added some photos below for you to enjoy as well as several Ameiglo and Glock sight articles. Always upgrade your stock Glock sights, they should be the first thing you upgrade. Also, I did not like the stock Shield sights, and I think they should be upgraded as well.
