I carry a Gen 4 Glock 19 in an Alien Gear 3.0 IWB on an Alien Gear Steel Core gun belt. The combination of this setup allows for comfortable carry, quick draw and presentation of my firearm, and Glock is designed to really be a combat pistol ready to fire without the need of having to worry whether an active safety is engaged or not (also why I carry with one in the chamber). The belt has a steel core which holds even a fully loaded compact the size of a Glock 19 to be held upright and in place quite nicely all day. The holster itself had a steel core which allows for a smooth easy draw as the slide guard portion doesn’t bend on you and also adds great retention. The backing of the 3.0 wicks moisture away from your skin and away from the firearm. This is probably the generic go to for most concealed carriers, but there is a reason it is. It’s a great set up, the price point for both firearm and holster is great while not sacrificing quality.
