As of today I'm officially a first time Glock owner, this is my first conceal an carry gun as well. Went with the 26 as I'm only 5'5 135 and really between the 26 and 27 I just didnt see a reason to go with 40 vs 9. Haven't gotten a holster yet, is that something I should order from Glock or where should I order from? Also what kind of customization can be done to the gun? Once again new to handguns really. Grew up hunting but always riffles.
