Plexico burress is the man when it comes to holsters. Just keep it loaded, saftey off and wear some baggy sweats to a nightclub. Thats the best way to conceal.
I use the Galco Sto-n-Go. I carry mine in the middle of my waist in back. I got the one opposite of my shooting hand so I can wear it this way. When you reach back with your shooting hand it is ready to go.
Holster is here. I LOVE this thing. It's looks big and bulky but is so comfortable to wear, and I'm sure it will get even better with time as it gets broken in. I also installed some Truglo TFO sights. These things are super bright, in daylight or in total darkness
