Weird problem with Mark III Hunter

[AKDRSS]

Only had this out two different times. Shoots pretty good but then if I relax my grip and allow my lower my arm to rest something happens. I bring the pistol back up and keep on pulling on the trigger without it going off. If I don't lower it it functions 100%.
Any thoughts before I call Ruger?

Are you allowing the trigger to reset?
Two handed hold, or one handed?

The disconnector controls how the trigger resets. When the trigger has been pulled and held back, nothing will happen until the trigger is allowed to go forward again. Then the disco will reset to the sear. With the relaxed hold he mentions, the "limp" wrist condition may not be allowing the bolt to cycle all the way backward to re-cock the hammer. Would be interesting to watch him shoot, though. You might try what was mentioned just above............a two hand solid hold.

Its not being limp wristed. The previous round is fired and ejected with no issues.

What does the trigger feel like when the pistol doesn't go off during refire? Does it feel as if there's nothing connected to it, or does it feel like the trigger is stuck and just won't move?

Are there any aftermarket modifications made to your pistol and its trigger?

Pistol is 100% stock. It's like you squeeze the trigger and it simply will not move. Then if I release the trigger pressure and raise it back up it will work as it should.

With the Ruger Mark Pistol you must release the trigger forward most of the way to allow the trigger to reset on the sear. The way these pistols work is when the bolt cycles the disconnector moves off of the rear sear surface and into a slot cut into the sear. While the sear is disconnected the hammer cannot be dropped by pulling the trigger. The bolt cycles back closed and the disconnector is still in the slot until you release it then it pops-up and re-engages the back of the sear to fire the next successive shot. You should hear a distinct 'click' sound when the trigger is reconnected to the sear.

Just got home from the range and all my shooting was resting my elbows on the table with the pistol pointed straight out. Fired 30 rounds and 3 or 4 times the trigger simply didn't "reset". I paid close attention to making sure all the finger pressure was off in between shots.

Going to be making a call to Ruger today as this one is going back to them to be fixed.

Take the receiver off the frame. Take a close look at the top of the disconnector lever, especially the top corner where the metal angles upward and meets the top edge. Is it dented right in that spot? Is there metal flared out on both sides of the disconnector lever? Just to be clear you're looking for something like this~

Cant tell you as it is already on the way back to Ruger.
Appreciate the advice though.

If it was, the pistol would need to go back to them for repair of the disconnector lever. Well, unless you wanted to purchase an aftermarket replacement disconnector lever from VQ. This condition would cause similar symptoms to what you experienced as the flared metal causes the lever to get stuck in the bolt recess for preventing out-of-battery detonations. I've been seeing a lot of disconnectors in this condition over the last few years.

Its a good shooting pistol and I just changed out the hi vis sights today for conventional sights so I hope they get it this minor issue ironed out.
