Px4 Question

I had a recent problem with my Beretta Px4 that I wanted to ask about. The Px4 uses the rotating barrel instead of a flip up type and during a recent weekend of shooting, it started having feed problems. When I took it apart, the problem seemed to be that the gun was dry. Somehow all of the Rem oil just evaporated. That's mostly my fault since I didn't check it before the weekend and oil it up.

But as a carry gun that concerns me. The question is should I be using a lube for the rotating barrel instead of oil, like with my 1911s. If so which lube would you recommend?
 
Well, it should run for a while even dry but I have no clue how many rounds you had though it before the issues surfaced.

I will also add that I have a lot of cleaning/lube guides on my channel and I generally say something along the lines of "any good petroleum based CLP will work fine. ...and I don't recommend RemOil."

Reason is, I've seen exactly what you described here WAY too many times. Someone please correct me if I'm wrong but I believe that RemOil is mineral oil with a teflon additive. If so, it would explain what we've both seen.
 
OP, I've heard that many people will put a small dab of grease on the locking lug portion of the rotating barrel. Myself, I just use old-fashioned CLP on all of my firearms, to include my PX4 D, and I've never had a problem, regardless of how many rounds I put through them between cleaning sessions.
 
It must have been very dry. I keep my barrel lubed good specifically on this rotating barrel in my full size and has kept lubed up even after extensive range use.
 
It was bone dry. I've never had this happen, even when shooting several thousand rounds in a weekend. I guess it's time to put up the RemOil.
 
In the What Lube is NO Good thread, Rem Oil is the number one answer. With so many other products out there, it might be worth trying something new.

Even so, you mentioned that it was "bone dry". Is it possible that more time has gone by than you realize? How much time has it actually been since you last oiled it? How was it carried/stored?

I know a lot of guys, myself included, that just use one kind of lubrication for everything. However, there is some truth to that old saying about oiling parts that rotate and greasing parts that slide. The rotating barrel is still technically sliding in there so a little bit of grease might not be a bad idea.
 
Still learning . . .

Okay, where should I go on the internet to learn the difference between a rotating barrel and a flip up?

I use Breakfree CLP to clean my guns and RemOil to oil them, including my PX4 and Stoegers 8000F and 8045 all with rotating barrels. Never had a problem with any of them due to lubrication. The trick to any lub is to use it, don't let any gun run dry!
 
Prof, as they say, Google is your friend. If you use "rotating barrel" and "tilting barrel" in the same search, you'll find enough sites to give you hours of reading. And for gun geeky guys like me, that is hours of pleasure :D

And there is a wikipedia site for anything. Really, I think it might be a Newtonian Law that there is a wikipedia site for anything.

This site has lots of pics, many of which show the rotating barrels of the Berettas and some showing the Grand Power. That last one is a gun made in Europe and just now available in U.S. of A.

Pics for Prof

As is always happening with Google, some of the pics seem to have little to do with the subject of the search, but those are toward the end.

I like to use a gun grease on the cam surfaces of my Px4, and the locking lugs on the barrel. Not a lot, but I leave at least a noticeable sheen of grease on those.

It is a great gun. Seriously. On Saturday I was out shopping at some favorite LGSs in my area and if I had seen a full-size Px4 in 9mm, I might have bought it to go with my compact one.

But then, the consolation prize is nice. Bought the first Walther PPS M2 I ever saw. And Sunday involved making loud noises with a small 9mm.

Yup, the rotating bolt idea is not new, having been used over a century ago. I thnk it may have been some old Steyr design but am not sure.
