OK, I like the idea behind the P320 and would like to get one in .45acp but the more I look the more confused I get.

There are THREE frame sizes: small, medium, and large.

There are FOUR grip modules: full size, carry, compact, and sub-compact.

So that's potentially 12 different configurations in each caliber?  

Does the gun come with all three frame sizes (S, M, L) when you buy it, or do you get whatever is in stock and in the box?  If it comes with, say, a small size frame, but you want a large, do you have to buy that frame separately?  

I ask because I'm looking at Sig's IOP price list and it doesn't mention what size frame you'll get, only the style (full size, carry, compact, and sub-compact).

Full Size, 9mm / .40 S&W / .357 SIG / .45 ACP
P320, .45 ACP, Pistol, Full size, 4.7in bbl, Nitron, BLK, DAO, SIGLITE, Modular Polymer Grip, (3) 10rd Steel Mag, Accessory Rail

I believe it comes with a medium frame.  I've seen frames at selway armory, about $45.

I have a subcompact in a 9.   Might want to get a compact .45 for it one day.

I believe the Full Size and Carry use the same size frame, just the slide is shorter on the Carry.... so only 3 different size frames Full/Carry, Compact and Sub-Compact...and I think the Sub-Compact only comes in Med and Small...
And then you have to take into consideration that the .45 uses its own specific frames, while 9MM, .357 Sig and .40 are interchangeable...
From what I have seen, all Complete firearms and kits come with Med size grips of whichever version you buy, and you have to buy the Small or Large frames if you want something other than the Medium size...
For reference this may help...

The subcompact, complete pistol, from what I hear, usually comes with a small grip, which has no rail. The medium grip, which is available as an additional purchase, has a rail.

Osage has listed the Carry, which is compact slide with cut down fullsize frame for 17rd mags, and also a model with full size slide and compact 15rd frame. So just about everything is offered.. I'm putting a compact slide on a subcompact frame as well.

Thanks all, I'm a little less confused now.

I don't think Sig should emphasize how much "better" their multi-sized frames are than backstraps, given the other manufacturers include the backstraps when you by the gun (at least Springfield does, not sure about S&W or big-G).  

Well, as long as they intend to support the guns with that huge variety of parts, I'm OK about it.

Follow-up question then.  You say "slide" by which I assume you mean, "slide assembly"?  In other words you're running a mid-size slide and barrel on a compact frame....correct?

That raises another question then.  Can I mix and match the barrels as well?  Can I run a full length barrel in a mid size slide on a sub compact frame?

The Full size and the Carry both use 17rd magazines, but the Carry's dustcover/rail is shorter to match the shorter slide.

Well the fact Sig raised their price on the conversion kits by $100 really hurts the whole idea if this thing imo. I think the best bet now is to by a full size of your favorite caliber and pay $100 for both the compact and subcompact frames to have the ability to downgrade grip sizes when necessary.

Personal opinion from alot of online research, I pick mine up this weekend, is start with the Compact model and get the Carry and the Subcompact grips.  The fullsize slide on the subcompact grip will fit and function, but leaves a gap because the dustcover on the SC is too short for the Fullsize frame.

Yeah I have the compact with an additional subcompact frame. I have found that I use the subcompact frame 90% of the time and rarely use the compact frame. If I want more grip length I just put a compact size magazine in.

So on Sig's fancy-HTML product page, down near the bottom, it shows all the frames together in one place.  The specs show little difference between the 'carry' and the 'compact' models, specs are almost identical.  

Here's where it gets hinky; on that page it looks like the CARRY is smaller than the COMPACT?

Carry and Compact respectively, from THAT page:



The carry model's rail has three bumps, while the smaller compact model's rail has four?  In the post above, they both have four.

What's the deal?

Hm... well, when you get a caliber exchange kit, you  basically get an entire gun, except the serialized FCG.  Still, it seems the FCG should cost more than $31.

Not to mention the 10% excise tax they have to pay for complete firearms, which is not due on the exchange kits.

Carry is the compact slide on a bobbed full-size frame so you have full-size capacity w/the compact's shorter OAL.

I am not sure this is right. Height wise the frames seem to be the same but the carry frame is still shorter in length then the full size fame.

If I am reading the specs right.

I think this is correct.  In the Shot Show video they describe the CARRY with a smaller slide and a full size grip.  The one he's holding has three lugs on the rail.  The COMPACT has a smaller slide and a smaller grip, and has four lugs on the grip rail.

Sig's product page shows it wrong, only adding to the confusion.

See highlight in red above. The full size frame has been shortened ("bobbed") to accommodate the shorter compact slide.

OK, I got my P320 in .357 Sig!  Very excited to get out and shoot the thing, hopefully this weekend if UPS brings the cartridges I ordered.  After that it'll be deciding whether to go with full-house Underwood or something more commercial like Federal or Rangers.

I have a question for those that have a couple P320s or even P250s: Has anyone tried running their P320 carry or compact with a full length barrel?  How about a subcompact with a carry length barrel?

With a carry slide on a subcompact frame there is the tinniest gap in between the grip/frame and the bottom of the slide, like 1mm or less.  It works just fine and I can't see the gap getting something stuck in there (I have heard of people welding/soldering the tiniest dot of material on there to fill the gap, I don't think it is worth the trouble).  I'm still testing mine out before I decide to carry it or not, heading to the range after lunch :)   poked around, this thread has decent pictures http://sigtalk.com/sig-sauer-pistols/28841-p320-carry-slide-sub-compact-grip-pics.html

And this article is about the 250 but the dimensions are the same as the 320 and it shows a full size slide on a subcompact frame: http://www.thetruthaboutguns.com/2012/04/chris-dumm/gun-review-sig-sauer-p250-9mm-2sum/

All the configurations function, but some are silly looking (like a subcompact slide on a full size frame)

I have SC and a couple Compacts.  I have not tried mounting the Compact barrel in the SC slide, but I can;t think off the top of my head why you couldn't.

Are you thinking of getting the longer barrel threaded for a suppressor by chance?
