Congrats on the new pistol. I have one in .40s&w and I love it. For the backstrap: Take out the magazine, just to the rear of the magwell there what looks like a metal bar. This bar is a u-spaped pin that holds the backstrap on. I use a scewdriver to get the pin started(carefully as not to damage anything) and then pull it the rest of the way out. It is pretty tight so a little difficult to get out. Once the pin is out, the backstrap will come right off. Reverse proccess to attatch the different backstrap. Hope this helps.

I wish you two well with your new Px4's..
Can tell you that I have had mine for 1yr, and she has shot 6150 rounds to date without any failures, but..
Myself, and it seems, many others, with 40cals and, we're getting a few reports of some (only 2 that I have been informed about, so far, and in cold temps) new 45's as well, are experiencing trigger sting.
Mine is a cold temp problem only, some others have it no matter the temp.
There is a grease application that can tone it way down, actually, nulify it completely, as it has in my guns case with the exception of temps that are colder than 59F down..
So, far, no problems with trigger sting with 9mm's..
If you do have any trigger sting, chk in over in Beretta forum, we have a thread on it, and it's in front of BUSA's eyes.
Best of luck to ya both, as it may, or may not be an issue with your guns.

Same way ON, same way OFF for all..
Quote: MS. 45, With the Pistol came a full back strap that is much larger than the other two small ones. How does that one go on?

...
Same way, push it on until it snaps flush, it sits outside the frame, semi flush, but not like the other smaller ones.. Pushing the retainer clip in may be hard as well, but it will go in with effort.
It will give you the tightest grip high up, if that is what you need.
IF in doubt, refer to the owners manual..

Great shooter, accurate, tame recoil, (in warm temps..)

Keep in mind that Beretta advises against dry-firing the PX4...
Just thought that I'd mention that out of the blue...

Dry-firing Ok with..
...
According to BUSA, it's ok to dry-fire if you have a snap-cap chambered.. recommend A-zooms
Must be ok, as myself and many others, using snap-caps have over 10,000 strikes, 6150 live fire for mine.. plus dry-firing.
Really helps break in and smooth out the trigger-action and pulls..

I only brought the dry-firing up to, hopefully, save someone some grief down the road...
Here's what the owner's manual that came with my 9x19mmP PX4 says about it (pg 67):
DRY FIRING/"DUMMY" ROUNDS
Dry firing is defined as firing a firearm with no ammunition in the chamber. Long term dry firing your Beretta PX4 Storm pistol may result in damage to the firing pin. "Snap caps" (inert chamber inserts that allow a firearm to be dry fired without damaging the action) are available at most gun stores for those who wish to practice firing without live ammunition.
CAUTION: If you want to practice shooting your pistol without using live ammunition (called "dry firing"), insert an appropriate "snap cap" into the chamber to cushion the fall of the firing pin and reduce the chance of firing pin breakage. "Snap cap" cartridges with spring loaded "primers" are ideal. The "Snap cap" cartridges with empty primer pockets are suitable for loading/unloading practrice but DO NOT PROTECT the firing pin during dry firing.
Unlike normal, I actually read my owner's manual this time...
For what it's worth...

I like Beretta manuals they are easy to navigate and have pretty pictures. The pictures help significantly when explaining disassembly of your weapon.

My PX4 Storm observations, being the happy owner of one:
My PX4 .40 has fired 1000 rounds of FMJ and JHP with no failures of any type.
I have not experienced the "trigger sting" I've read about, and I shoot mostly 155 JHP loads, pretty hot.
I do not agree that the rotating barrel softens recoil in any way. The slide comes back in recoil just like the slide of a tilt breech type pistol. "equal and opposite reaction" applies here just like in everything. By the same token, I do not feel any rotational torque either. I think this is just an image in people's minds. I'd be delighted to read a physics description of how a rotating barrel softens recoil. My M&P .40 is a softer shooter, just because of grip shape. My HP .40 is a softer shooter because of all-steel (more weight) construction. But I don't find the recoil a problem. My P99 recoils more because it weighs less. And so on.
The rotating (not-tilting) barrel allows straight-line feed, which I feel contributes to feeding reliability.
I like the chrome-lined bore, a Beretta feature I appreciate.
