About The Ruger PC Carbine
The rise in popularity of a pistol caliber take down rifle was met head on by Ruger, in the PC Carbine. Comparable to the Ruger 10/22 take down model, it can be easily transported or stored away in a small space, yet has the stopping power of 9mm ammunition. The PCC features interchangeable magazine wells. Included are the Ruger SR Series mag well and the Glock mag well(fitted for any of the 9mm doublestacks). Take down is simple and straight-forward, pushing a lever forward and twisting the barrel off with the bolt in the open position. The fluted barrel measures 16.12 inches and comes threaded. Charging handle and magazine release are ambidextrous and can be moved to either side to suit your personal preference or needs. Trigger components are similar to the 10/22. Equipped with adjustable ghost ring rear sights and fixed front sight, both mounted forward of the receiver. Half inch spacers at the recoil pad and buttstock allow for adjustment in stock length to fit your reach. Recoil is reduced in this model by the heavy tungsten dead blow weight that shortens the bolt travel, providing for less muzzle rise and quick target acquisition. Picatinny rails provide for further customization and attachments. Specs listed below.

There is really a lot to love about this gun. It’s always important to note, when you are having malfunctions with a new (or newly modified) gun, that most new firearms require a bit of a break in period. A majority of users report absolutely no issues straight out of the box, which says a lot about the quality of Ruger products. Ruger, like any other serious gun manufacturer, has a reputation to uphold. Their customer service department is willing to troubleshoot and replace parts, as needed. With that being said, let’s look at 3 problems with Ruger PC Carbine you should know about.
Pistol caliber carbines deliver better accuracy, velocity, and recoil control than their handgun counterparts—while feeding from the same magazines you already have. The Ruger PC Carbine delivers that “one-round” capability, along with the expertise that comes from making pistol carbines for nearly 60 years…far longer than most other manufacturers.
Problems/ Solutions
Problem 1: Failure To Eject
This problem occurs when the spent casing is not properly ejected from the gun once it has been extracted from the chamber. You may hear it referred to as a “stove pipe,” as it often leaves the casing standing straight up preventing the bolt from closing. This is the most common complaint or problem with this model. There are a few things that can cause this to occur, but in most cases people have found one of these two solutions to be effective.
Ejector: If you are using the Glock magazine adapter that came with your purchase, Ruger has identified that slamming the magazine into the well with too much force can actually bend the ejector out of shape causing the malfunction. Very few problems have been reported using the Ruger mag wells and magazines. If this happens using the Glock assembly, you can simply remove the ejector from the Ruger adapter and use it on the Glock adapter. Some people have bent theirs back into proper alignment with no issues.
Extractor: In several instances, it has been found that after the gun has been fired the extractor is not “grabbing” the cartridge with enough force and it just sort of spins it out, instead of a clean forceful pull out of the chamber. There are a number of videos online showing how to file down extractor to give it a more defined grip on the casing. It is not suggested to manually alter the internals of your gun, unless you are a licensed gunsmith. If you are not a gunsmith and you aren’t brave enough to go all in and start filing on your own, a lot of people are seeing success by upgrading to an after-market extractor. M*Carbo offers a wide variety of upgrades for the PC Carbine, including the Exact Edge Extractor made from A2 Tool Steel, which seems to be a better design and stand up to wear much better than the original part.
Problem 2: Failure to Feed
This problem occurs when the next round fails to feed into the firing chamber. In most cases, this was also seen in conjunction with the Glock set up. While most double stack 9mm Glock magazines work fine with the PC Carbine, some of the larger capacity magazines are seeing issues with failing to feed the last several rounds. This can be attributed to not having enough spring tension in the magazine to push the cartridge up into place. It is advised to use newer magazines, if you are having this issue, or replace the springs in your magazines with heavier ones. Inspect the Feed Ramp. It’s always a good idea, if you’re having feed issues to make sure the path from magazine to chamber is smooth and debri free. Polishing the feed ramp is a common step taken to ensure a smooth transition. It has also been noted that upgrading the extractor will make for smoother bolt action and help with any feed issues. So, the Exact Edge Extractor could be a fix for both Failure to Eject and Failure to Feed problems. Below, Hickok45 troubleshoots problems and gives feedback on his experience with the PC Carbine.
Problem 3: Trigger Fails to Reset
This problem occurs when a round is fired and the trigger does not reset to fire the next round. This is very rare, but for those experiencing it can be very frustrating. It is likely due to faulty or weak trigger return spring. Some people have seen success with removing the spring and stretching it slightly. As with some of the other solutions mentioned above, there are also after-market trigger assemblies available that will resolve the issue. If you have an unreliable or faulty trigger mechanism, it is advised to contact Ruger and have them guide you. This could easily present a safety issue and should be taken seriously. The following video shows someone having issues with trigger reset and ended up having multiple discharges from a single trigger pull.
Conclusion
Any experienced shooter has, at some time, dealt with malfunctions. It’s bound to happen, if you shoot enough. Problems and troubleshooting are a good way to get to know your gun and all of its internals on a first name basis. Knowledge is absolutely fundamental in being prepared for worst case scenarios. It is far better to deal with an issue at the range and learn your firearm, than be blind-sided when you absolutely need it to function properly. If you are experiencing any of these 3 problems to know about with the Ruger PC Carbine, you are in an ideal position to increase knowledge about your weapon.
