Do you have descriptions and or part numbers for the numbered items?

Meme, here's a link to a Diagram with part # (for the Sigma9V) at Brownells.. They also have diagrams/parts for the 40V and other sigma models.. (actually, just about all S&W SemiAuto's)

Bullit, call S&W and tell em the trigger on your 9VE is hard and gritty.. They'll pay for all shipping, and the work is free.. I heard it's only a 2 day turnaround as well.. (Read about this in the "smithing" forum) Let me know how it goes..

Tony, how about some pix?? Your mods sound very interesting, but w/o pictures to go along with the instructions, most of us are hopeless..

My turnaround was 7 days the Smith had to go in for Emergency for an Illness the day the gun got there. The trigger breaks on mine at 5.5 pounds now. I am tickled pink over S&W Service. They also put on a new rear site also.

You are correct that the pin only goes in one way. It is a "stepped" pin meaning one end is smaller in diameter than the other end. Therefore, it only goes in one way-you cannot put it in backwards-you were right about that. It is in the right hole as well because if you put it in the bottom hole-the trigger rod can't be connected.

You indicate that the "sear ramp" may hold it in-what exactly is the sear ramp?????

If it matters, I can duplicate the problem with the slide removed. There is pressure on the sear when the gun is cocked (usually hammer pushes the sear towards the barrel of the gun) this releases the pressure on the top pin, and allows it to fall out. When not in the cocked position there is tension on the top pin and it can't come out. I can't see any type of retention system for this pin-and am wondering if something fell out when I was taking it apart. If anyone has a picture-please post it up! Otherwise, I will tig weld a small tab to prevent the pin from backing out-but still allow removal when/if necessary in the future.

I don't understand why S&W attempted (they missed the mark) to make it as complicated as it is. I could achieve BETTER results, with half the moving parts that they have used, and it would be of higher quality and have greater durability. The cam design of the sear riding on plastic is NOT designed for long term usage. Further, the fact that the cam portion of the sear is not finished well and is very rough will guarantee that the plastic wears over time. I have only put 150 rounds through mine and already there are witness marks & scratches on the plastic where the sear rides.

Actually, it's a very durable design. I have two of them; one with about 5000 rounds through it, and the other with close to 2000. Neither of them have ever had so much as a hickup. There are other folks who have many thousand more rounds through their Sigma's than I do mine, and they are still going strong.

There is a reason the gun is designed the way it is, and while there are probably other ways it could have been done, the Sigma is a proven platform. It is functional, reliable, durable, and safe.
