Hi Guys, Ordered a Ruger PC Charger Target Hammer and shims from you guys the other day, I am impressed!!! The old trigger pull was about 6 pounds and up, but once I installed the kit, it took it down to a 2 Pound Pull. Thank You ~ Max

Searching the internet we found some users have reported that the Ruger PC Carbine experiences a trigger reset issue. Specifically, the trigger may fail to properly reset after each shot, preventing follow-up shots. Thoroughly cleaning the trigger assembly as recommended in the owners manual or at is advisable.
On a stock rifle if the problem persists, contacting Ruger for assistance would be advisable.
If you decide to modify the rifle trigger assembly with aftermarket parts, and continue to experience fail to reset issues, the culprit is often a weak or faulty return spring. You might consider stretching the spring or replacing it with aftermarket parts. Additionally, TriggerShims has an Extra Power Trigger Return Spring available. Consult a qualified gunsmith if you have questions

PC Carbine Trigger Reset Problems

Item# VC10B

TriggerShims Customer Tony Writes;

Lance, after I installed the VF9TH I started to have trigger reset issues, so I tried several different things.
I have at least 4 to 5 hundred rounds through mine now and it feels solid . No reset issues at all.
Here is a list of what worked for me;

  • VF9TH Target Hammer with custom ground hammer bushings
  • TriggerShims trigger shims on the trigger
  • M*CARBO aluminum straight trigger shoe with supplied reset plunger and spring
  • M*CARBO Bolt Buffer Block
  • M*CARBO Extended Bolt Handle
  • M*CARBO Extractor
  • M*CARBO Trigger Pins
  • Some light polishing on the Disconnector Assembly

That trigger assembly really is not that complicated when you get into it. Maybe you can pass this info along.
It seems to be working... Tony B

Item # PC Reset Tandemkross Fix

PC Carbine Trigger Reset Problems and Tandemkross Fix

Greg from Michigan writes that he cured his reset problems;

I had trouble with the trigger not resetting between rounds.
I have the M*Carbo bolt buffer pad installed, which is ever so much thicker than the original for which the trigger assembly was designed.
After talking to Volquartsen about modifications, I broke down the rifle again and also found one corner of the M*Carbo pad sticking up.
I re-installed the original Ruger pad, fired the first two fine then stopped again. Then I put my finger to the very bottom of the curved trigger, thus gaining leverage, and fired six rapid fire twice without a hick-up. Put another mag in and fired 4 more. Problem solved for the time being.

Shot an entire 5 stage SC course without a single fail to reset, or any other issue keeping my finger to the very bottom of the original curve trigger. Trigger pull had been reduced to 3-3.5 lbs.
Ordered a Tandemkross Victory Straight Aluminum Trigger, Tandemkross Bolt Buffer Pad, and a new Hardened Extractor. The Tandemkross Bolt Buffer Pad IS thicker than the original but NOT as thick as the M*Carbo. It also has a nice aluminum frame unlike the plastic from Ruger.

Went to the range and put out about 100 rounds, slow and rapid fire switching targets from side to side and top to bottom. Not a single issue, especially no fail to reset!. By switching to the Tandemkross Victory Straight Aluminum Trigger with the Volquartsen VF9TH Hammer the pull weight dropped to a repetitive 2lbs. Gauge never went over 2lb 2oz.

Republic. I like the sound of the word. It means people can live free, talk free, go or come, buy or sell, be drunk or sober, however they choose. Some words give you a feeling. Republic is one of those words that makes me tight in the throat - the same tightness a man gets when his baby takes his first step or his first baby shaves and makes his first sound as a man. Some words can give you a feeling that makes your heart warm. Republic is one of those words. - John Wayne in the Alamo
