Get the Grit (gritty feeling) out of your Taurus PT111 G2, PT140 G2, 709 or 740 Trigger

I have three Taurus pistols with the trigger system used in the PT111 G2, 2 PT111 G2s and a PT140 G2.  The first one I purchased has thousands of rounds through it and the trigger is very smooth with a pull weight in either single action or double action of just over 4 lbs on average.  The second pistol has I would guess about a thousand rounds through it, and the third is brand new (PT140 G2).

The trigger on the PT140 G2, and to a lesser extent, the second PT111 G2 have a gritty feel, particularly in the last bit of their travel before they release the striker.  I went on a mission last week to see what I could do quickly and easily (no major disassembly and a process that could be done in 15 minutes or so).  Sure, I know I could completely strip the frame, polish all the bits that rub, and have a trigger every bit as good as the oldest one on all three triggers.  But, I also know most folks don’t like to do that and I wanted to see if I could find an easy way to get at least part of the benefit of a stoning and polish job.  Or, if I could avoid having to expend a thousand plus rounds to get a smooth trigger, so much the better.

The first thing I did was remove the slide from the pistol.  I found the striker moves in the slide without any of the gritty feeling and was pretty consistent across all three pistols, so I set the slides aside.

Next, I worked the triggers on all three pistols, paying particular attention to what was moving when they felt gritty.  Time for a photo:

What I found is that on the last little bit of trigger movement, when the part marked with a blue arrow above moves, the trigger felt gritty.

I also looked at the well worn in pistol, and its trigger bar looked polished for nearly a half inch towards the muzzle from the disconnector.

The trigger bar can be moved around with a finger.  The new pistols felt very gritty as it was moved both up and down and back and forth.

To cut to the chase, I also found I could get most of the benefit of the polish job by applying a lube (in this case a grease, like Tetra gun grease) in the areas in the first photo shown above.  It takes a toothpick, to work it all along the top and sides of the trigger bar while holding it down below the disconnector.   I applied it liberally and worked it in.  Then, I took a cotton swab and cleaned out the excess.

The two newer triggers are almost as smooth as the old trigger with that done.  Since the springs are still a bit stiffer, the pull weight is still a little higher on the new ones even after lubricating the trigger bar.  I had sprayed CLP and Rem oil on the trigger bar area with no improvement.  I also cleaned out the trigger bar and the rear mechanisms as best as I could with GunScrubber before lubricating it again.  A lubricant like motor oil, manual transmission fluid, etc may work as well.  I think it takes something with more film strength than CLP or Rem oil.

If you have a gritty trigger, give this a try and comment on whether it helped or not.  I would love to hear if this works for others.  And, have fun shooting those Taurus pistols!

  1. On Facebook a PT111 G2 owner did this using STP for the lube. That is probably a great choice and would be easier to get into the trigger bar area than grease. Here is what he had to say:

    Noticed a grittiness to mine when taking up the slack in S/a been scoping around on mine, I just did mine in that area with a small amount of stp, and it is better, also a small touch at the transfer bar in the trigger housing and was butter.

  2. I cleaned my PT111 G2 very well, sprayed everything thoroughly until it was dripping everywhere with gun scrub and then cleaned again. After everything was dry I sprayed it down again with WD40 and cleaned again. After the WD40 was all dry I applied a light coat of STP to all the surfaces of the slide, frame and trigger using Q-tips and toothpicks to get it into, onto and behind every part. Last, I removed any excess WD40 with Q-tips and sprayed everything lightly with gun oiled. No gritty feel and the trigger pull went from 8.2# to 6.1#. I have about 1000 rounds thru the gun now and I hope it gets down to Alfonso’s 4&5# ones.

  3. Fantastic information and posted Jan. 3rd, my birthday! I’ll try this little trick. Thanks Al.

  4. You can also slip a piece of 1500 grit sandpaper (folded works good) between the trigger guard and frame and with the slide off work that trigger hundreds of times while you watch TV.
