Not by any means knowledgeable about Glocks. I'm in process of building one and looking at slides. What I'm building is a G19 Gen 3 compatible. I see lots of different types of slides out there. Some fairly skeletonized, some with cutouts milled for red dot sights. Looking for opinions and advice to help decide whether or not to get a pretty vanilla slide vs. one of the more expensive ones with all sorts of "features" listed that I don't inherently understand the utility of. Thanks in advance folks!
