Nice job Steve and great results for whatever trigger you choose as well. Thanks for doing the werq so the rest of us slackers don't have to. ;^) Oh, and thanks for the pics you know need them.

Is there a difference in trigger pre and over travel when using the adjustable sear with the stock and TKO trigger?

i'll test it in. 3 screw frame.

I'm out shooting in a trapshoot today and tomorrow, but should get some time Monday to fiddle with it.

Is the gun cocked in pics 1 and 2?

...movement of the sear (which is my preference), then none of these combinations produced any. The sear is visible when the grips are removed, so it's easy to watch and see that every mm of blade movement produces corresponding motion of the sear.

What changes is the ratio of blade to sear motion -- high during the 1st stage, low during the 2nd.

Overtravel was comparable for all.

...there's so much slop in the pivot pins when the side cover is removed that part positions aren't representative of what they become in the fully assembled action, anyway.

Meanwhile, I'm working up my courage to post one more picture, revealing a gruesome deed I committed to get your trigger to have a proper 1st stage in combination with the non-adjustable SS.

But first you have to promise not to yell at me.

There may be some fitting involved with the 1911 even with the factory sear. I noticed several early 2240 2-screw frames had slight differences in the location and diameter of pin and screw bosses, etc.

The 3-screw frames "seem" be be more consistent.

Some filing, grinding, welding, hacksawing, a bit of chewing gum and some vasoline or K-Y might be required on parts (and/or people) designed without consideration of other related enhancements!

I sent 2 triggers, so you have a "control" and a trial part.

Mike

P.S. It's freezing and raining here ... been outside all day. I'm whupped.

...the 13oz 1st stage and 1lb, 4oz 2nd stage that the (ahem) "modified" blade below achieved are actually kinda' pretty.

is applicable here, but considering there's nothing to be seen on an assembled gun anyway, it's all good- form AND function! And it's the first thing I thought that could be done when I saw the photo of the overlapping sear and trigger. Anyone who's fitted FCGs into 1911 pistols (of the PB type) wouldn't see material needing removed to fit the parts as out of the ordinary except maybe the amount of material removed.

In any event, thanks!

Thanks for "taking one for the team" Seriously, nice job with the pics, composition, etc. I think you could have also ground the bottom of the 1911 unit (where it establishes the preset), to have enough travel for the first stage. Thanks -
