EDIT: I should have added 4th gen to the title. Thanks! Hi guys. I've search for this information but can't seem to find a good answer. I know there are two main variants the G19 and the C which is the compensated version. Since my G19 will be for self/home defense I've read that's not a good option. My question is what are the different variants beyond that? Some of the options I've seen for sale are fixed sights, steel fixed sights, night sights. Which is pretty self explanatory. I've seen ones that say PST, wasn't clear in the description what that meant (maybe it's pistol - lol). I've seen ones with a "flat dark earth frame". Saw one called "Talo Exclusive" which looks like was just night sights. I've seen a "25TH ANVRY" on the G17, not sure if that is offered for the G19 also. I've been on the glock site but can't really find much information on the different options beyond the C version. I'm not sure if the different flavors I'm seeing are site/shop specific upgrades. Thanks for any insight you can offer!
