1911 recoil springs

I have a SARO Elite Target model with the excellent Eulette optics rail Jon mounted for me and an UltraDot. I was using Brazos HiTek 180gr LSWC and 4gr TG .469 crimped Federal brass. Shot fine, but was inclined to try 3.8gr TG with a .465 crimp as some think the tighter crimp is better. Loaded them up went to the range and FTE the first 2 with a #10 Wolff spring. Can’t seem to find the #9 I should have laying around, I can order one np. Any suggestions on a lighter spring, or just go back to the 4gr TG. I can’t speak to accuracy differences as I was in league slow fire and just loaded up the old 4gr ones and finished the night.

Find the 9 lb spring and try it.

They have an assortment.  I bought it.

I bought the Wolff calibration pack which is supposed to come with a #9 but I can't find it...
I can order down to #7 but not sure what I should need...

You probably know this stuff but thought I'd chime in.

The firing pin stop can be radically reshaped to reduce the amount of resistance it offers to the hammer.  Also, the mainspring (hammer spring) can be replaced with a lighter one.  The final and most expensive option is to replace the hammer with a Cammer Hammer.

Cool, I learned something today ))) Never knew of "cammer hammer", sounds like a neat idea.

The website says go heavier until you get a  malfunction then go to the next lighter.  I think you are there.

Hello,

I have seen many pistols start to have lock up (accuracy) issues when going below a ten pound recoil spring.  I wouldn't recommend it.  If it won't function with a ten pounder, I would up the load.
