1911 Hammer Spring

Nice pistol job, Bob. I really like those grips, they match it well.

Thanks for the compliment on the gun.
I finished the grips with hand rubbed Tru Oil, then hand waxed and buffed them.
After building this gun I built several more for customers that wanted one like it, I've also had several offers to sell this one but I think I'll keep it for awhile.

Can you explain why a lighter main spring does not affect trigger pull weight?

It does effect the pull weight, Dixie Gunsmithing did a good job in explaining it.


I thought the center leaf was to push up the disconnector? please explain?

The center leg or leaf of the sear spring resets the disconnector along with returning the trigger.
If you reduce the pressure to much on the center leg you will have slow trigger reset along with possible connecting failure of the disconnector.

When tuning a sear spring I tune all three legs.

OT, but I like the looks of that gun, Bob.
The upswept grip safety and bobbed spur in lieu of the ubiquitous beavertail and burr are a breath of fresh air.
And the absence of French fried borders, lack of roughening of non-grasping surfaces, and moderate dehorning in lieu of heavy bevels are refreshing, too.

I am leaning back towards arched mainspring housings, though. All my guns with flat have wraparound grips, all the ones with bare frontstraps have arched.

Gladly,All moving parts affect each other and as I pointed out a lighter main spring has little if any noticeable effect on trigger pull,this is because the sear/
hammer engagement surface is only .030" so friction is not significant enough to
be a factor and that is what you would like to reduce to decrease pull weight.
As to the center leaf,it has two functions and this is why some aftermarket
springs have four instead of the standard three one is to keep pressure on
the disconnector and the other to spring back the trigger assembly.
This of course is a separate issue from the displeasure that the integrated lock
causes some owners and I think that somehow they got mixed in this thread.

Thanks, Jim.
Judging by the amount of customers that have requested I build them a gun like this one or one very similar to this one, I would say many feel the same way we do.

Mike,

One other thing about sear springs I forgot to mention in my e-mail, if possible buy the Colt sear springs as they are the best.

As for the four legged sear spring, I used them at one time.
However the center legs are thin and do break causing some serious malfunctions in the gun.

Thanks Bob, I already ordered Wolff springs. Are they passible, I have had good luck with them on my revolvers. If not I will look for the Colt springs.

The leaf spring discussion was brought in by you. you stated the the center leaf was responsible for trigger pull weight. While it does push indirectly on the trigger stirrup, the amount of pressure that leaf puts on the stirrup seems negligible.
My own experience seems to be consistent with Dixie Gunsmith. I can get G.I. parts down to a 4.5 and 5 pounds without changing the angle of engagement. Swap out the 23 pound main spring with an 18 pound one and the weight drops around a pound

You are welcome Mike.
I've never used Wolff sear springs as I prefer the Colt sear spring.
However I would think Wolff springs would be of good quality, I know their main springs and recoils springs are.

I got the proper main spring cap, plunger and retaining pin to for the flat main spring housing and used a 19lb spring. There was a useful but not huge reduction in trigger pull. I will shoot the gun like this for a bit to make sure I have reliable ignition and there are no problems then pay some attention to the sear spring. Anyway, for those that are considering changing to a lighter main spring my experience is that the trigger pull was reduced a noticeable and useful amount. The pull is still a bit on the heavy side but I'm not looking at the gun to see if the safety is still on now. Sorry, I don't have a trigger pull gauge so I can't tell how much it changed.

Thanks for everyone's help

Mike
