P320 Modularity Explained

[Blaster229]

Should be a sticky.

So many different variations between full size, carry, compact, slides, barrels, etc... I found this post on SigTalk and it is an excellent reference.

What slides fit on which modules. Great pictures too.

SLIDE LENGTH:

The P320 comes in four (4) slide lengths, which are in turn based on barrel length. They are as follows:

5" Barrel- X Five, X Five Legion
4.7" Barrel- Full Size, P320 VTAC, RXP Full Size, M17, etc.
3.9" Barrel- Carry, Compact, XCarry, RXP Compact, M18, etc.
3.6" Barrel- Subcompact, XCompact, RXP XCompact

Wilson Combat grip module is the best one in the game, imo

Is that one yours, SkiPatrolDude?

Indeed. Only other mod is the skeletonized trigger shoe, otherwise it’s stock.

If you want polymer, it's pretty good, and I run them on my P365s. I like the AXG and TXG better for performance purposes.

Someone at SHOT was also introducing a steel grip, which should be something like 11-12oz heavier than the TXG:

M1823 Grip Mod – Steel

THE TIME HAS COME!! Production of the Chromoly M1823 Grip Module for the Sig Sauer P320 has begun! In an attempt to satisfy the overwhelming and enthusiastic response from the community, we decided to leave it in your hands, end the wait, and begin the ordering process. We understand...

You'll pay for it, especially with the magazine well, but if you want to run a P320 in Limited Optics, it might be worth it.

List price is more than a whole gun, any idea what street price is?

That's the price. It's not out of line with a Cheely 2011 steel grip.

Thanks erwos,

I've seen a discussion once where the opinion was that polymer grips give more flex, thus there may not be any advantage to a heavier metal grip. Anyone want to debate the merits of this?

It's nonsense. There's a difference in recoil "feel", but physics is a cruel mistress, and there's a world of difference between 30oz and 50oz.

ETA: I have a Cosaint COS11 "single-stack 2011" with polymer grip and steel frame, and a Girsan MC1911S with a traditional steel frame. The Girsan weighs like 10oz more, and the difference is pretty stark recoil-wise.
