OK, I am new to owning my own Glock, but have been issued a Glock 22 for years. I just purchased a Glock 23 with factory night sites for off duty use. I have a couple of questions. 1. Are the factory night sites any good? What brand are they? Is the front site going to fall off like the plastic sites on our issued Glock 22's? 2. I plan on using the Glock 22 High Caps as reloads. How far out of the bottom of the grip do the 22 high caps stick out of the 23, and is their any type of grip extender device that I can add to them to make them look a little better? 3. What do y'all think of your 23's? Are there any upgrades that are recommended out of the box, or should I just grab it, load it, and shoot it? 4. I need some holster recommendations for the following holster types: a. IWB b. SOB c. OWB d. Mag Pouches I prefer kydex, but leather is OK, I have used Fobus Roto in the past, and feel like they are OK. Thanks for all of your help, and this seems like a pretty good resource!
