I was not a fan of the finger grooves either, I like the gen 5 grip much more.I like the Gen 1 and 2 Glocks. Don't care at all for the Gen 3 and 4 Glocks. The Gen 5 is better now that they've done away with the horrible finger things. Those just did not work for me at all.
Glocks are like a reliable tool. I carried them on duty for years because they were very reliable and very lightweight compared to most other choices. When all the gear you wear on duty for 8 - 12 hours every work day weighs 40 - 45 pounds, a little weight savings is a good thing.
I look at our Warriors and all the stuff they have to wear and feel like a total lightweight complaining about my cop gear. I saw all the stuff my son had to jump with and I don't know how he carried it all.
That's why these days I almost exclusively wear shorts and a t-shirt with flip-flops or tennis shoes.
