Very nice. I love my Glocks. Shoot long, and shoot often.
For carry ammo, I like Hornady Critical Defense/Duty. The Critical Duty is a tad bit hotter than Critical Defense, but both are great shooting. I find that round to cycle through all of my carry guns from Glocks, S&W M&P's and Sheild (most 9mm's), and my 1911 45's, (and a dozen or two others). For bulk practice, I use my own reloads so I can afford quantity bangs. Then always finish any practice session with the ammo brand/model I plan to carry.
I don't have night sights on any of my Glocks just yet, but do on my 1911's that are my preferred EDC. When I do get then, will be the kind with dual illumination (I forget the brand names) with tritium vials behind fiber optic rods. Best of both worlds, illuminated day and night. My bedside gun is a G22 (.40 cal) with light/laser combo. Works great around the house, but a little too bulky for my preferred carry.
For holsters, I make my own OWB's, so obviously they are my favorite.

. [hobby, not for sale]. But for IWB, I really like Cross Breed. For me, the key to comfort in ANY holster, is to have the gun completely moulded on the outside of the back/body shield. No matter if it's inside or outside of waistband. It's the best way to remove pressure points from the body and increase the level and longevity of comfort. That is how I make my own all-leather holsters, and that is how the cross breeds are done also. Only they use kydex for the gun mould, then attach to leather or horsehide body shield. I like the the CB's with horsehide because it's a little thinner for the same level of strength, with better moisture properties.
I carry 7 days a week, the entire time I'm both breathing and wearing pants. The two holster styles mentioned above fit probably 98% of my carry needs. The other 2% I'm either being creative with pocket holsters, which may also require grabbing a smaller gun. Micro .380's, .38 Snubs, or super micro "Derringer" style like NAA Mini's.
This is my favorite carry rig.
And my hand cannon. [emoji23]. Ok, more of a conversation piece....but id'nt it cute?
