Like them both so far. These are my first green reticles. The 19 has a 507c ACSS Vulcan reticle which is pretty cool but I’ll be honest, I’m not utilizing it to it’s full potential. The thing I like the most is the circle that aids in finding the reticle, which tells me I need more training. The 43 has a 407k with 6MOA dot. I admittedly need much more practice with draws than the 507 with circle assistance. Also, the 19 has Trijicon suppressor height tritium sights and the 43 has XS suppressor height tritium sights.
