Question: Does this holster fit the PX4 Storm in .45 standard?
Document: Slim Pickings when it comes to finding a holster for a PX Storm, especially in left handed. This holster is very comfortable and the gun fits like a snug-bug-in-rug. Will not fall out. You need to pull it out. I was concerned because I am use to the Blackhawk Holsters with the release button but this holster fits very well and again you need to pull it out intentionally it will not fall out.
I've tried about 6 left hide belt holsters for my Beretta PX4, and until now, I hated them all. This unit is all I can ask for, given an affordable price.
It is a well made Holster  easy to adjust and wear.It is a little hard to conceal after wearing IWB for so long.
It's hard to find reasonably priced left handed holsters but here's one that's pretty nice. While it may not be Kydex, the material (thermoplastic?) is stiff enough to support and grip the weapon properly. Retention is a combination of friction and a slight bump which falls into the trigger guard and is adjustable by tightening a screw. The paddle allows it to go on/off  the hip easily (a feature I like) yet keeps the weapon pretty close to the body.
Answer: yes
