Handgun enthusiasts today have more options than ever before when it comes to the size and fit. Users of the Sig Sauer P320 are no exception. The Sig P320 comes in four different sizes (Full Size, Carry, Compact and Sub Compact) and each size has either two or three grip module sizes available. Each grip module has a two or three letter designation on the lower part of the backstrap. Below is a table showing all possible letter combinations for the eleven grip module options. The black box denotes the size module that comes with the firearm from the factory.



We hope this helps shed a little light on which P320 model and size you have.

As an owner of a 320 sub c and c, they both have TG on them. While the oem ergonomics are great, TG makes it all of the better.
I have a 320 full. It just has a single m on blackstrap?
If you have a “M” on the module you have the medium module. The P320 Full Size comes from the factory with a medium module.

Does the P320 45 ACP pistols only come in Full and Carry size?
Do the Full and Carry size pistols ship with Medium Grips?
The P320 45 is available in both compact and full size. The full size/carry and compact ships with the medium module.
I have a p320 compact can I get a sc and clip to convert to subcompact
Thomas,
Good question. You can go from a P320 Compact to a P320 Subcompact pretty easily. Here is a video of how to make the transformation.

What size do you suggest for the Sig P-320 M-17 ASP .177 Airgun.
Thanks
It appears to be a 1:1 replica so our P320 M17 grip for the medium module should fit perfectly. To be sure of the module size I’d contact Sig Sauer. You can find our P320 M17 grips here-https://blog.talongungrips.com/pistol-grips/sig/p320.html
Full size medium and compact med are same size?
The full size frames and compact frames are different sizes. The compact handle is shorter than the full size.
What is the frame size for Sig M18
Tim,
Good question. The M18 has the Medium Full size/Carry Module so you would need TALON Part number 003.
You can find the grip here- https://talongungrips.com/gun-grips/pistol-grips/sig-sauer/p250-p320-m17-9mm-357-40-45/
Best,
