Nothing like snow and cold weather to get me in the tinkering mode:

Installed the new single action trigger last week on my G2. Liked it so well I bought another one and just installed it on my 709. Basically followed the YT G2 install video by Keep Tinkering. The G2 & 709 are almost identical. There is no install video for the 709. There are a few differences that I found out as I went along. Haven't been to the range yet.

It appears that there are several frame pin variants of the 709: 4 pins (mine), 3 pins, and 2 pins. I'm only familiar with doing this on my 4 pin model and would issue a word of caution on trying this with the other variants, especially the 2 pin model. If there is any interest I can share more details.

PS - On 3/05, 2 days ago, I went to the range and ran 16 mags through her. Each mag holds 7 rounds so I fired off 112 bullets. There was only 1 incident in which the trigger failed to reset giving a dead trigger feel. This involved only one bullet early in the test.
Today, 3/07, I returned to the range and fired off 16 mags all without failure. So far so good!

Fantastic -- I'm glad you like it

My 709 will be done soon with TK's trigger

pt111rat: How many frame pins does your 709 have? The model with 3 pins I think is most like a G2. That, in the trigger housing, there is a pin securing it. With mine, being 4 pins, the trigger is secured in the housing with a frame pin. Once putting mine back together, the new trigger would bind up. So what I did was use a shorter pin that just secured the new trigger within the housing itself. If you look closely at my pics, it looks like it is missing a frame pin. But I feel the front frame pin sufficiently holds the trigger housing to the frame. Doing it this way there is no binding. Not wanting to cut short the frame pin, I used a finishing nail that I cut short. Approx dimensions need to be: 0.65" X 0.094". Or you could go to Harbor Freight and get their roll pin assortment set.
I had to lightly sand the bottom of the trigger so it wouldn't rub on the inside of the guard. Doesn't take much.

Hey BoB
My 709 has 3 pins just like the pt111 g2
Thanks for the infro. on the sanding of trigger I will keep a eye on that
Now I like that laser -- others I do not like and that's the 1st that I've liked

As much that I like my 111g2 Full DAO I decided to change the 709 to SAO - KT's trigger yesterday and that laser just reinforced me to make the 709 my night stand gun

That's the CT Laserguard 447. They're a bit pricey but well-made.
