Spring Length for 45 Long Slide?

I have an inbound Clark Long Slide coming my way. Do these use standard springs, or do I need longer springs for it? I am hoping to set it up for a #68 with 4.1 WW231.

On a related note, if I change out the trigger to a 90 grain unit, will I likely still get hammer follow if I don't pull the trigger when dropping the slide?

You want a long slide calibration pack.

I’ve used standard government length springs in my long slides for 30 years. I just use a heavier weight. Since we don’t know how good your barrel locks up, it’s hard to guess appropriate poundage. I would guess 13-14# with government length spring.

Hello Brent375hh,

EGW sells a spring plug for six inches (6") M1911s that will enable you to use standard government length springs.  I can heartily recommend them.  I have had to go down to twelve pounds (12#) springs to get my long slide M1911s to run with loads that would normally use a sixteen pound (16#) spring.

Forgot about those Jim

I shoot a long slide. I have an extended plug in mine that has recess built into it for using spring for a government/5" slides. 
I use an 11lb spring with a aimpoint 9000sc slide mounted. Probably go up from there if the dot isn't mounted on the slide/running irons.

This is what I have in mine. I think it's the same thing GWeber is talking about.

It appears that it came with a standard length 16 pound spring. It only functions about half the time with 4.3 WW 231 and a 200 grain 68. I cut a few coils off , but it still isn't 100% and now seems a little sluggish going into battery. I guess I have to wait for my spring order.
BTW it is 12 degrees out, so I was sluggish too.
