Congrats! I’m not sure if they have a holster for your model but I’ve bought 3 holsters from Tulster.com and have really liked them. Their mag carriers are good as well. Also get yourself a good belt. I thought I had a good belt but was quite wrong. My buddy directed me to Versacarry and I just ordered a new belt from the actually. They’re thick and the belts are on sale, or at least they were when I ordered mine last week.
Definitely get a small lock box like what’s posted above. Of course you can’t carry everywhere and you’ll need somewhere to secure your firearm. I’ll drop the mag, clear the chamber, lock the gun and carry my mag for in the off chance somebody does break in and crack the lockbox they will just have a gun but would need to try and find a new mag and ammo, good luck with either at this point.
I’m lean enough to comfortably carry appendix. It takes some getting use to but it doesn’t bother me anymore. I’ll carry around the house and do chores and it doesn’t bother me much. I like 5 o’clock as well though the cutouts on the slide dig into some of my side fat a little and I don’t like that much after a while. Do yourself a favor and also get an OWB holster for when it’s cold and you can carry with heavier clothing on and nobody will notice. Not sure if you got your Conceal Carry Permit right away or not (NV is 120 days) but if you didn’t I’d recommend getting your holster now and practice carrying concealed around your house. This will help you get ready for when you can legally carry.
In the car I keep it holstered and 99% of the time it’s appendix. What I’ll do is lift my shirt and jacket up over the gun, if I have a jacket on, so that I get to it quickly if I need. Somebody makes those big magnets you can mount in your car, so that could be a good option for long trips. Keeping a second holster in your center console or something isn’t a bad idea for long trips either. Just make sure you can get to it quickly.
