The full sized 9mm/.40 S&W/.357 Sig grips will all work with the conversion units of any of these calibers, as will the full size or subcompact grips of these three calibers. For .45 ACP, you will need a grip frame (full, compact or subcompact) specifically for that caliber pistol.

I spoke with Sig on Friday regarding shipping on the .40 caliber compact conversions and they should be leaving the factory within a week (once the magazines are paired with them). The .40 S&W subcompact conversions are not expected out until 01/2009.

Ok, let me get this straight. I buy a .45acp, in compact. Can I order a 9mm kit, that will work. If I read your answer correctly, the .45acp has a set of frames for that caliber only? Full, compact, and sub-compact. Standard trigger, or short. One other question. Do the frames have changeable backstrap grip sizes? Or is that just figured in on the size frame you choose? Sorry don't mean to be so dense, I thought I had figured it out. I need to go to the website and watch the video again.

Nope. Sorry for the confusion, but only the 9mm/.357 Sig and .40 caliber grips are interchangeable. Example: A compact 9mm grip will work with a compact upper in calibers .357 Sig and .40 S&W. A .40 S&W full size or subcompact grip will work with 9mm or .357 Sig full sized or subcompact upper. If you want to changed the caliber for any of these three pistols, all you need to purchase is kit containing the new caliber slide, barrel, recoil spring system and magazine. It isn't necessary to replace the grip, unless you want to convert the weapon from one overall size (ie: Full size, compact or subcompact) to another.

The .45 caliber grips will only work with .45 caliber uppers. If you own a 9mm compact and want to convert it to any size .45 ACP, you will need to purchase a .45 caliber grip that matches the new upper. Like the other grips, the .45 ACP full, compact and subcompacts will be available in small, medium and large sizes .

All this is predicated on the info coming from Sig. Time will tell, if and when all these things come true.

pulicords,

Sometimes I’m a little thick so please for give me. Just for clarity, let’s assume I buy a complete Sig 250 pistol in .45 ACP. If I understand your post correctly, in order to reuse the pistol section (the serialized assembly) in a different caliber I would need to do the following:

1. Buy an additional grip frame for a 9mm, .375 Sig or .40 S&W.
2. Buy the conversion kit for the caliber I wish to use.

Did I get that right?

My understanding is that 45 version is not compatible with 9mm, 40S&W version at all.

Modular also means within a given caliber, such as from compact to full size, sub compact size and changing grip size. It's also meaningful for maintenance purpose. Caliber conversion is not the sole, or even primary, focus. Not that you are claiming that.

Hell, that pretty much kills it for me. Time I do all that I can buy another pistol. So if ya want a .45acp. that is all you get, except for changing the size of it. The only calibers that interested me was the .45 and the 9mm. But no swap around capabilities, with each other no need to wait for the 45. Once I find a size that fits me I generally don't downsize it. Even for CCW. Oh well.

I'm also waiting to see what actually comes out and what it sells for to determine if buying a .45 P250 and then buying a different frame and 9mm barrel/slide/etc. costs less than just buying a new 9mm P250 to go along with the .45. My guess is that it will be a bit cheaper.

Same goes for getting the full-size and sub-compact set ups. Even if you stick with the same caliber, it looks like you will need to get a new frame, slide, barrel, and magazines -- everything but the "gun module."

PLEASE Don't make me read 53 pages to find out WHEN the 250 sub-compact (small) will be available in .357 Sig? Want one bad..

I did, took me all day. Well off and on all day. Your guess is as good as mine. I will talk to a Sig dealer tommrow. Maybe he will be able to shed some light on the subject. You can read the last 6 or 8 post, and see what I am dissapointed about.

I'm not so sure you are right. The "gun" in the P250 is the serialized module and nothing else. In order for this not to be compatible with the other modular pieces its construction has to be different. I can understand that the frame, rails and slide are different on the .45 but I’m having difficulty with the “gun” (the serialized module) being different.

Yes. The grips are selling for about $50.00. The caliber conversion kits retail from Sig at $369.00.

Test Pilot: According to Sig, all calibers will be compatible with the modular frames, but the .45 ACP grips will not accept 9mm/.357 Sig/.40 S&W magazines. If you want to convert a pistol in one of those calibers, you will need to purchase a .45 ACP caliber grip and vice versa.

OK, now I'm confused. I have a 250 and the "pieces" are:

1) Grip/Frame (I use these to describe the same thing because the frame and grip are one piece)
2) Magazine
3) Fire Control Assembly
4) Everything else (slide, barrel, spring)

So, if I currently own a 9mm compact frame/grip (#1 above), I can't just buy the .45 ACP conversion kit (#4+#2 above), I also have to buy a frame/grip (#1 above) that will support the .45 ACP mags. I never have to buy a fire control assembly (#3 above). I think that is correct based on what I'm seeing above.

That's the way I've understood it from everything I've read. 45 cal conversion from the current 9mm will require the large grip, barrel, slide, recoil spring assy, mags. The only thing you're moving from the current gun is the trigger assy.

Converting to the smaller calibers requires barrel, slide, recoil spring assy, mags. You can take the current grip and, naturally, the trigger assy.

Might as well take a stab at this. "Conversion kits" include barrel, slide, recoil spring guide, magazine AND GRIP MODULE! In Sig's pricer there are:

Fullsize and Compact kits for 9,40, 357, and 45.
Subcompact kits not shown, but should follow above.

Grip Modules , includ mag catch installed 9,40,357 45 has their own set, as below.

Compact Small
Compact Large

Subcompact not listed, but expeted to be the same. REMEMBER THAT 250'S THAT HAVE SHIPPED COME WITH "MEDIUM" GRIP STANDARD!.

Hope this helps some?

So the kit comes with everything but the trigger assembly/module -- cool! Thank you for clarifying that.

Chris

The trigger assembly/module is the one part of the original pistol that will always be present, no matter how the rest of the weapon is modified. The gripframes for .45 ACP (Full sized, Compact and Subcompact) will be available in sizes large, medium and small to accommodate different hand sizes, but none of them can be used for the other calibers (9mm/.357/.40) because of the different external dimensions of the smaller caliber magazines.

The grip frames of the three smaller calibers, only need the slide, barrel, recoil spring/guide assembly and magazine(s) of the alternate conversion kits to change caliber. (ie: changing a 9mm to a .357 Sig or .40 S&W of the same sized weapon-Full/Compact/Subcompact) If you want to change a 9mm Compact to a .357 Subcompact, in addition to the .357 Sig Subcompact conversion kit, you will need to spend the extra $50.00 for a corresponding grip frame (Subcompact).

Changing any of the "small caliber" pistols to .45 ACP will require the purchase of a .45 ACP grip module, in addition to the kit.

I just thought of a possible problem with 45apc and the 250. Someone mentioned that they thought the 250 45 might have worked with 45 only and I couldnt figure out why that was possible. Then I thought about it, the registered part of the pistol has a space where the mag well and the bullets come up through. I havnt measured it yet but if sig didnt think about it prior to updating the design from germany, the mag and bullets will be too big to fit through the hole. If it does fit then you have to wonder how much that effects the frame size of the current 9mm gun.

Koga, if I understand you correctly, a 45 "kit" will have a "medium" 45 grip module with mag catch installed, along with other necessary parts. If moving from 45 to others, you get all the "upper" parts, plus "medium" grip module for 9, 40, or 357?

When do the P250 9 mm long frame hit the market.

faksen.Sig is not offering any date on full size 9, only soon to come full size 45! Keep watcching the board! When something is known it will be posted.

My issue was not with the frame or slide I know you have to replace them. It was the little space in the registered part that the bullets have to go through.

Again I was just thinking on what someone else said that 45 was only 45.
