I carry 1 of 2 S&W Shields in 9mm (both have Ameriglo front night sights). The loaded mag has a magguts +1 and the spare has a SI EMP +2 extension. So 18 rounds total of Hornady Critical Defense or Federal HST. Of the 4 guns I qualified with to carry, the Shield is the one I shot best and can point shoot with. I’m on my 6th Shield holster, and this one is made by Last Line of Defense. The LLOD holster is pricey, but so worth it. The mag and gun retention is adjustable, build into the mold is a raised strip that acts like a wing/claw, height adjustable and the best part is the single raven clip allows the holster to move with you, so it’s more comfortable. I think I have finally found the best AIWB holster for me.
