LAKELINE STAINLESS STEEL SLEEVE
(for Taurus PT111-G2, PT140-G2, G2S, G2C, G3, 709, 740)
NOTE: The Lakeline instruction say some firearms may require the use of a drill to enlarge where the sleeve inserts into the slide. I found this not to be the case, your situation or model may vary.
I purchased a Taurus PT 709 Slim in May 2018 and have put over 1000 rounds through it since. Although the gun has performed well, there was always a feeling of it having a gritty trigger, felt like when I pulled the trigger I could feel it going over a bump.

Reading some posts on various online forums I spotted one that mentioned a fix in the way of a stainless steel striker guide sleeve that would replace the OEM polymer sleeve and possibly fix this grittiness. The sleeve is made by Lakeline LLC (P/N PT-SG-NS-004). For $20 I decided to give it a try. Their website is: https://lakelinellc.com/
The Lakeline sleeve has a fine finish, much smoother than the OEM polymer orange sleeve:

However, the Lakeline sleeve disables the slide-mounted Taurus Security System (TSS). The Lakeline sleeve does not have the hole for the TSS that the OEM sleeve has. I believe this hole was also causing the “bump” felt in the trigger.
A) REMOVING THE OEM POLYMER GUIDE SLEEVE
1) Disassemble the gun as you normally would for cleaning:

2) Here you can see the OEM (orange) polymer sleeve and back plate:

I used only 3 tools: pin/punch, tweezers, .22 shell casing:

3) Place a pin/punch as shown in the photo below and push the orange sleeve towards the front of the slide (towards the left in the photo)

4) At the same time, carefully remove the back plate while not letting the striker spring slip out. Once the back plate is slightly moved you can put the tool down and with both hands on the slide remove the back plate, followed by the striker assembly.

5) With the spent 22 shell in the orange sleeve and placed on a hard surface, compress the striker spring using the tweezers (or your fingers) and remove the 2-piece striker keeper. Slide the large striker spring off the striker and pull the striker out of the orange sleeve. Ensure the smaller spring on the striker is retained.

6) Place the Lakeline sleeve onto the striker as shown, then reinstall the striker spring.
7) Reinsert the 22 casing so the striker spring can be compressed in order to reinstall the 2-piece keeper.

8) Reinstall the striker assembly into the slide and reinstall the backplate.

10) Reassemble the gun and you are finished!
I could feel a difference as soon as I dry fired the pistol. A few days later I took it to the range and ran approximately 75 rounds through it with zero problems.
This modification, in my opinion, is well worth the money and time spent, which took less than 1 hour.
