xpd54 Posted February 5, 2019 Share Posted February 5, 2019 (edited) Apparently it’s a thing. Happened to me today. Ruger PC9 unlocked itself cliff notes version - shooting fast resulted in the quick detach, detaching on its own. And yes, the nut was checked. Did this repeatedly.

Steve RA Posted February 5, 2019 Share Posted February 5, 2019 That is interesting, wonder if anyone else has experienced that ??? Yours is the first post I've seen pointing out that problem. Link to comment

Yours is the first post I've seen pointing out that problem. It has happened. I think I read about it in a field test in NRA mag or something. Had to send it back if I recall. I won’t buy take down guns for this reason. Link to comment
Steve RA Posted February 5, 2019 Share Posted February 5, 2019 Yes, I can see that. Takedown guns are usually alright if they don't "take down" on their own. Link to comment
cityofthesouth Posted February 5, 2019 Share Posted February 5, 2019 (edited) Guy I know got one that would come apart slowly while shooting. If memory serves the barrel/forend would rotate slightly and then prevent the bolt from going fully into battery. I at least got to witness the "malfunctions" at a Steel Challenge match, but didn't get to handle it personally. He sent it back to Ruger (I believe he said twice), they said it was fine, the outfit he bought it from offers a satisfaction guarantee and eventually just refunded his money.

BlackBuzzard Posted February 5, 2019 Share Posted February 5, 2019 (edited) Little Loctite will fix it up real good. Edited February 5, 2019 by BlackBuzzard Link to comment
DesertTortoise Posted February 6, 2019 Share Posted February 6, 2019 Tighten the nut untill it is difficult to take it apart, then it should be good. I think they all do it though :( Link to comment
BigBamBoo Posted February 6, 2019 Share Posted February 6, 2019 Got a bunch of guys here at the local club running them and we just tighten the barrel/taken down nut until you can barley take it apart. Never had it loosen up or see anyone else’s loosen up once set up like this. Have about 5000 rounds through mine. Link to comment
xpd54 Posted February 6, 2019 Author Share Posted February 6, 2019 I’ve done the whole barrel tightening thing. Still does it. Already called Ruger. They’re gonna take care of it. At least I have it on video so they cant say it isn’t happening. Hopefully they get it squared away. Link to comment
ParaGunner Posted February 6, 2019 Share Posted February 6, 2019 Interesting, I've got over 1000 rounds through mine of fast shooting and no signs of unlocking. I do tighten the lock down nut with the rifle apart, then force it back together. Locking nut has never once loosened up once assembled. Definitely something I'll watch for though. Link to comment
xpd54 Posted February 7, 2019 Author Share Posted February 7, 2019 I got to thinking, can someone post a pic of the bottom of forearm where the locking lever is? I don’t think mine was going far enough forward. Link to comment
ABQautoxer Posted February 8, 2019 Share Posted February 8, 2019 I'm not near mine but if you take off the hand guard (that one allen), you can make sure nothing it interfering with it. Link to comment
xpd54 Posted February 8, 2019 Author Share Posted February 8, 2019 Can’t. It’s on its way back to Ruger Link to comment
RocketRyan Posted February 8, 2019 Share Posted February 8, 2019 I was probably the first person this ever happened to, I was in talks with Ruger Engineers/Head of their PCC product line guys. This is a design flaw with the takedown pin. They use a really tapered pin to seat into the receiver, unfortunately it provides no ability to lock it into place. I find that the "locking" nut actually does not prevent this at all. It's easily replicated by pulling the fore end into your shoulder and twisting at the same time. I checked out a newer PCCarbine at the gun shop and it seems they may have a newer style takedown pin that should fix this. I ended making my own takedown pins that had no taper and milled the receiver to match. I went from barely getting over 5 rounds before it would break free to 12,000 with no issues. I hope they get this fixed for you (Mine was back and forth for two months with Ruger before they gave up and offered me a refund etc, I ended up fixing it myself). Video back from April 2018. https://www.youtube.com/watch?v=cST_3Ds7Dnk I no longer use the Ruger in competition since mag changes were holding me back in classifications. I now run a JP with zero problems 5K+ since mid December. Link to comment
xpd54 Posted February 23, 2019 Author Share Posted February 23, 2019 Got my PC9 back in less than 2 weeks. According to the paperwork they replaced a bunch of parts related to the lock assembly. Ran some rounds through it and so far so good. Link to comment
