I don't carry a single-stack handgun at the moment. My current carry options are:
- 9mm Glock 19 with 15+1 rounds
- Inside the waist band at 4-o'clock in a NSR Tactical holster as everyday carry
- 9mm Glock 26 with 10+1 (standard magazine) or 12+1 (extended magazine) rounds
- On my left ankle in a Galco Ankle Glove holster as backup gun or when deep concealment is needed
- Below the waist band at 12-o'clock in a SmartCarry holster when jogging or when deep concealment is needed
- Inside the pant pocket in a DeSantis Nemesis pocket holster when skiing
- Inside the waist band at 4-o'clock in a NSR Tactical holster when deep concealment is needed
- 10mm Glock 20 with 15+1 rounds
- Inside the waist band at 4-o'clock in a NSR Tactical holster when hiking
I am considering a single-stack handgun for the following carry options:
- Inside the suit pant pocket as backup gun to the Glock 26 at 4-o'clock or as only gun, both when deep concealment is needed
- Inside the waist band appendix carry as everyday carry backup gun
Note that I usually carry two 17-round 9mm Glock 17 or two 15-round 10mm Glock 20 backup magazines. The Glock 17 magazines fit in the Glock 19 and Glock 26. A good belt and a good holster go a long way in distributing the weight and keeping the gun close to the body when carrying inside or outside the waist band.
As you can see, for me it is all about options. Please consider your options. What are your needs and what are your restrictions in daily life? Also, get some defensive handgun training to learn how to effectively defend yourself and/or others with a firearm when the need arises.
