    Question Considering buying a PX4 .40, but have some questions regarding the Rotating Barrel

    Hey, I've got the urge to buy a new gun this week. I'm currently looking at a PX4 storm in .40 SW. Is it a good firearm? More specifically, does the rotating barrel affect the ballistics? Will I lose fps because of the rotating barrel? Thanks for the help guys

    There's a pic at what I'm looking at getting.

    Another question: can I buy a low profile slide stop without converting it to a type G model?

    This is just MHO but I'd shy away from a new 40cal. LE is shying away from the 40cal and switching calibers. What are the Chinese packing these days? Or are you OK with a battlefield pickup?

    I've heard that. James Yeager took some serious flak for his videos on .40's sucking. However, the rotating barrel mitigates a lot of the recoil (from what I've heard) so it's not so snappy. That's why I'm wanting to pick up a PX4 in .40. I'm still curious as to how that will affect the ballistics of it though.

    I don't have it in .40 but I do have the PX4 in 9mm. I can attest to the fact that the gun is 100% reliable through several thousand rounds including IDPA and IPSC competition. It shoots as well as my skills allow!

    A couple of things:

    First this isn't a rifle or a precision target pistol. Change of a few FPS and exterior ballistics (a MOA or two of accuracy) DOESN"T MEAN SQUAT. A rotating barrel doesn't mitigate recoil....recoil is a factor of inertia...mass and acceleration of the bullets coupled with the mass of the sidearm.

    With that out of the way, "FELT" recoil is affected by the the rotating barrel because the barrel isn't tilting, so there isn't as much "flip" to the recoil. I have the Beretta (and a Stoeger) Cougars in 40 S&W and the impulse feels slightly different and follow up shots MIGHT BE slightly easier as the sights seem to be quicker back on target, but any difference is really minor and unless you dwell on it and focus on it, you don't notice any difference.

    As for ballistics, the bullet has left the barrel before it twists and unlocks, just like the bullet has left the barrel before a barrel tilts in standard (or modified) browning lockups, hence zero affect on ballistics due to the twisting of the barrel.

    What's all this about the Chinese and .40 cal?

    Don't have a .40 but do have a 9mm, one of the best shooting pistols I have very shot. Also have a 8045 Cougar, it is a smooth shooter. I do believe the rotating barrel is the reason, the barrel stays level as the recoil takes place not raising up as in normal semi autos.

    I have a PX4 in 9mm and a few other 9mm pistols.. For it's size the PX4 reminds be a bit of a pitbull dog.. smaller, thicker, compact.. The recoil does feel less when shot then the others.
    As stated in another post the bullet has left the house before that barrel does it's spin and ejection cycle.
    My only issue is the sights.. at first I seemed to always be shooting WAY low with my PX4 but on targe with the others... found the problem and worked it out (me) now not only am I on target with the PX4 but shooting much better with the others.. btw I was scrunching my neck so my eyes came down to the sights instead of lifting the pistol up higher, common issue with shooters..

    all my pistols are 9mm because I think it is a great round, easily found for sale, inexspensive, and if SHTF should be still easy to find.
    Wheelguns are .357/.38

    I really like the pistol for many many many reasons.

    Slide release... yea. It would be the same as the standard S/C release.

    Decocker... you would have to make your own. Having both, I would not suggest "Stealth" levers in F. Not enough meat to get ahold of it to go up with it. Decocking works ok with those levers.

    Beretta didn't do them in F likely due to that. Needing to take the gun off safe and not being able to is a kind of big problem. Wouldn't want to see that through.

    I've got the PX4 in .40 and love that gun. I love the way it shoots.

    My wife bought a PX4 Storm in .40 a bit over 5 years ago and loves it. She shoots well with it. I've shot it as well, and it is well built, nice to shoot, and has decent accuracy. Good self defense gun. She bought a Sig P238 a little over a year ago that she likes better because it is easier to operate with her arthritic hands, but kept the PX4. Just my .02.

    Sweet, must've picked a good one then. I cannot wait to get my grubby hands on it. I feel like my only complaint will be cleaning it after excessive usage!!!
