Description
SIG built the P250 and P320 around one core idea: swap the outside, keep the guts. This grip module is a piece of that puzzle, giving owners of either platform a way to reconfigure their .45 ACP pistol into the Carry size without touching the fire control unit that actually makes the gun run. It's a factory piece straight from SIG, so tolerances and fit line up the way they should against your existing internals.
Grip Feel on the 45 Auto Carry Medium Module
The medium grip circumference splits the difference between the slimmer small option and the fuller large, which makes it a solid starting point if you've never measured your hand against SIG's sizing chart before. Molded from black polymer with SIG's standard texture pattern, it gives you real purchase under recoil without feeling rough enough to chew through a range session. The Carry configuration keeps the full grip length of the larger frames, so your hand gets the same amount of real estate to work with even though the slide and barrel up top stay shorter and more concealable.
Putting Together Your P320 or P250 Carry Build
This module is the frame piece only, so you'll need to drop in your own .45 ACP fire control unit along with a compatible Carry-length slide and barrel to finish the conversion. It ships without a slide catch lever, so if you're moving from an older grip module you may need to grab an updated one separately to make sure everything indexes correctly. Once assembled, the module runs on full-size .45 ACP magazines, giving you a 10-round capacity in a package that's noticeably easier to carry than the full-size slide.
Why Go With a Genuine SIG Grip Module
Buying direct from SIG rather than an aftermarket maker means you're not gambling on tolerances or magazine release fitment. The reversible magazine release built into this module keeps things workable for both right and left-handed shooters, and the polymer construction keeps the whole setup light without feeling flimsy. For anyone who already owns the internals and just wants a different size or a fresh frame, this is about as straightforward as a P320 or P250 upgrade gets.

Frequently Asked Questions
Does this grip module include the fire control unit?
No, this is the grip module housing only. You'll need to transfer your existing fire control unit from your P250 or P320 into this module to complete the build.
Will this grip module work on both my P250 and P320?
Yes, SIG designed the P250 and P320 to share grip modules since they use the same basic frame architecture in .45 ACP. As long as you're matching the Carry size and .45 ACP caliber, this module should drop right in.
What else do I need to finish the conversion?
Along with your fire control unit, you'll need a compatible .45 ACP Carry slide and barrel assembly. Keep in mind this module doesn't come with a slide catch lever, so double check that your current one is compatible before you start swapping parts.
How many rounds does the Carry .45 ACP configuration hold?
This grip module runs on full-size .45 ACP magazines, which hold 10 rounds. You get that same capacity in a shorter, more carry-friendly slide and barrel length compared to the full-size gun.
