    I recently got a PX4C RDO, and itís a great shooting gun but it is really easy to induce a failure to feed, especially when shooting SHO. Even freshly cleaned and lubed, itís got a very pronounced hangup when chambering a round if anything at all is slowing the slide down. Iím pretty new to guns, and coming into the px4 from glocks which are in my experience pretty laissez faire about lubrication, so Iím sure that at least part of the issue Iím having is related to that. It almost seems like the angle of the feed ramp is too steep, but I think itís more likely that Iím missing something rather than that beretta got something wrong at the factory. However, itís because of QC problems at the beretta factory that I have the PX4 instead of the LTT compact I initially ordered, so who knows.
    I had some teething issues with my px4cc when first got it. Mine is a base model bought from Robar when the first came out. I had failures to feed at first as well. I accepted it as a break in period and continued to shoot it but I also looked into possible causes. First off I noticed a burr on the plastic near the top of the feed ramp. I cleaned it up gently with some emery cloth as noted in this pic: Name:  3BA57B90-4F19-44D6-8664-991DF5565D03.jpg

    The second thing I did was disassemble all of my magazine and cleaned them with dawn dish soap. I remember reading I think somewhere in this thread that there can be some gummy residue left from the factory in the mag body. Sure enough they needed cleaned. After letting them dry out I sprayed the inside of the magazine with dry Teflon lubricant, Iím not sure it was necessary but I didnít see how it could hurt.

    Thirdly, I noticed that my thumb position while shooting was causing some drag on the slide. I adapted my grip slightly to avoid touching the slide.

    I have not had any failures to feed since doing these three things. I will also note that my px4cc does not like steel case ammo at all, it will jam in the magazine consistently. I rarely shoot steel case ammo anyway so this is not as issue for me. Hope this helps, a new gun that doesnít run well is frustrating. Let me know if you have any questions about any of the above.

    One of my Px4CCs was very sensitive and would fail to feed by not fully returning to battery sometimes. I replaced the recoil spring assembly and it didn't happen with the new one.

    I only have one PX4cc - it was the tricked out one from Robar when they first came out. I have 8,500 rounds through it. My first malfunction was at 6,700 some odd - it was a FTF. The second was in that same range visit with a FTE. I took it as a sign to clean it for the first time Ö and called it a successful 2000 round challenge. I wanted to push it a little moreÖ so shot it to 7,000 with one more failure (FTF). Have cleaned it and been good to go. It is due for a new recoil spring, I know. Also, mine has been fine with the steel case crap ammo (occasional range trip with buddies) but it is worth noting my mags are NP3 coated. YMMV. One data point. Yada, Yada, YadaÖ

    I think the NP3 coating makes a big difference with the mags. Eventually I plan to but some NP3 mags from Langdon to try out.

    I have been really pleased with the NP3. My understanding is that it is a coating not currently available for the end userÖ meaning there is not a way to send things to be coated by Robar any longer. Is that true?

    I should note that both the gun and the mags I used are NP3 coated, I chose that option hoping that it would be a little more forgiving of less than frequent lubing.

    There have been some great suggestions here, Iím going to take it out one more time and see if the FTF issues persist with fresh lube, then Iíll likely contact LTT either way and send the gun back to them if they deem it necessary.

    I've got mine (PX4 D) on now, going out to Sunday dinner with it. The slide is about the same as a G19, while the grip is about the same as a G17.

    You'd be good with either.
