1911 3.5" 45acp 1911 Builders kit barrel clearance

Hello, All
Just helped a brother finish up his 1911 45 bobtail
1911 Builders complete kit
3.5" bull barrel
Clark/Para/L cut
Stainless
Checking fit, barrel at link down clears slide by 0.013.
Without slide stop pin same measurement
Dye confirms legs contacting VIS nicely and barrel contacting bed.
Bottom of barrel feed ramp .003 off top of frame.

Am I worried over nothing or should we lower the bed and move the VIS a couple thou?
Full disclosure TJ is helping me with this also just looking for all the information possible
Thanks
Al

On page 191, Vol 2, of Kuhnhausen, he recommends .010" clearance minimum.

Which is exactly what he may have as .013"without slide stop pin in place and .003" under when it is, would leave .010". Why he has .013" with, or without the slide stop pin in place is confusing, when stating there is .003" under the barrel to frame. But is adequate either or.

Every thing you all say is correct except .013 with or without the slide stop pin. No additional clearance at the bed .
The 0.003 I mentioned is between the bottom of the barrel ramp and the top of the frame at the CPL cut.
Thanks

It seems the minimum clearance in this area is subjective. Schuemann states .015" and somewhere I read .020".

Schuemann says 0.015 with link/ slide stop installed, 0.020 without slide stop if I remember correctly

He does on the website, perhaps product protection. However in his written directions that come with his barrels he says .015" and .010", I called him on this and he agreed that what was written was correct. He indicated that you sometimes have to overstate to get what is reasonable.
