My 2 bits....
For a Beretta PX4 9mm, Id look at a Predator holster from
www.Wrightleatherworks.com . The new Master Class series looks good.
I like the coffee color. The Wright Leather magazine holders seem lacking but you can buy a 5.11 or Blackhawk magazine rig.
www.Blackhawk.com
Wright holsters may take a few months or weeks to get. High Noon Holsters is a decent firm too. They list the PX4 pistols for the different styles.
The synthetic Skin Tite models are cost effective & ready to ship for most holsters.
Other top brands include Alessi, Galco, El Paso Saddlery, Kirkpatrick Leather, Kramer, Mitch Rosen, Mernickle, Ted Blocker.
Contact the holster shop first for prices & delivery times. Minor changes or styles may prevent them from making the holster for your model.
