One of the first holsters I ever purchased that was not specifically for concealed carry was an Uncle Mike’s gun holster.   It had a metal clip that that was very secure on a belt, and it was made of nylon.   It worked very well for me for several training sessions and it had a front pocket that could hold a double or single stack magazine with a velcro strap to secure it.   I never had a real problem with the holster since it is made of nylon and isn’t as harsh to lay down on as a paddle holster.  Many paddle holsters aren’t going to tolerate roll overs.

I have thought long and hard about what type of handgun to have with me as a secondary firearm and the thought came to me that it really should be all about up and close fighting and then flee the situation and clear my primary and get back into the fight with that.   I don’t carry about caliber wars between 9mm and 45acp, I will gladly fight a handgun battle with an M4 Carbine.   My secondary firearm is a  fitted with Wilson Combat magazines for a Colt 1991A1.   I carry one mag in the gun, and 2 in a vest pocket.   I don’t think over loading myself with handgun ammo is a good thing and 24rds of 45acp is good enough for me to fight my way out of a situation.
