Looking for a Slide completion kit for .45 cal. AB proto type in description states their kit covers a .45 (out of stock) All other kits don't mention .45! What parts or part is different?

This may not be a complete list and the part numbers provided may have been changed by Sig. Make sure you call Sig's Customer Service to confirm before ordering.

These are components I believe to be different between the P320 .45cal vs. 9mm/.357Sig/.40S&W versions:

Slide
Barrel
Recoil Guide Rod

Striker Pin
Safety Lock (1301017-R)
Extractor Spring Pin (Sig changed their design in 2017, and maybe again at a later date. Be careful ordering from non-Sig suppliers as they may send out of date parts:

FCU Frame/Receiver
Take Down Safety Lever

Grip Module
Magazine
Magazine Catch (38030030-R)
Magazine Catch Stop (38000060-R)
(The Magazine Catch & Stop might not be different between the two versions. At one time Sig used different Part Numbers for the two versions and I am not sure if that numbering is currently in place.)

On the FCU I thought the only difference was the slide catch lever??

I believe the Slide Catch Lever is the same between the two variants but please call Sig to confirm.

The P320 has a Magazine Safety, the Take Down Safety Lever wraps around one half of the inserted Magazine. The Take Down Safety Lever must fit the different sized magazines.

For the 9mm/.357Sig/.40S&W, the Take Down Safety Lever is Part Number 1300734-R. I do not have the .45cal Take Down Safety Lever Part Number and again, please call Sig for confirmation.
