I finally got my sig p229 in .40s&w and could only be happier if one thing is possible. The one I got, due to availability, is double action only. My ? is; can I convert her to double/single action with a decocker like they normally come? The space is there on the frame for the decocker and from what I've see. On other p229's I would think its an easy job. Any help is much appreciated.

Wow. I have a P229 SAS E2. No clue. In sure there is a kit or modification maybe. I think the best bet would be to chat with a gunsmith. One of them should know. It's a great pistol and live mine.

Speaking of the P229: what are the possibilities for converting the 229 from one caliber to another?
I've been told that you can change b/w 9mm and .40 with a barrel change, but if you get a .357 it would not accommodate any other caliber conversion? What is the rule here?

I would get a complete 9mm "upper" through Sig. Then you can go between 40 and 357 with a barrel swap. And a different upper for 9mm.

Rule is if you have either the 40. or 357. you can swap barrels straight across and down to 9mm but if you have in 9mm then you must buy the caliber exchange kit to go up to 40. or 357.

The reason I'm asking is that I want a .40, but found a used .357 at a local gun shop that is absolutely mint. The guy at the gun shop told me I wouldn't be able to swap in a .40cal barrel, he said you can only swap down in caliber, not up. I'm just trying to understand why that is if you're changing the barrel?

And if a 9mm can be swapped with a .40cal (which is bigger), why can't a .357 accommodate a .40 cal barrel? Or is it something that I just have to accept as not being available?

Thanks.

The 40. barrel and the 357. barrel have the same od just different id the 9mm conversion barrels have the same od and will have a thicker wall something like a bull barrel.check here at www.efkfiredragon.com or www.wolf.com for conversion barrels.I found that Sig makes a conversion barrel in 357. and 40. but only a conversion kit in 9mm.If you buy in 9mm. unless you buy a conversion kit you will not be able to get just a conversion kit.However swapping between 357.and 40.is an even swap across.

It may depend on the series of the P229. My SAS E2 in .40 can be changed to a .357 with just a barrel swap and nothing else. To move to a 9mm I would need to change the slide and use a different magazine. I would be using the same lower. There are conversion kits available online.

I don't know about other P229's since I haven't used them.

So, if I have a P229 in .40, will I need just a barrel conversion to take it to 9mm? And then what mags would I get to hold 9mm bullets? Thanks all!

Yep. That's right. You can look on midway USA for the conversion kit. Come complete with upper(slide,barrel, etc) and a mag. I don't think there is anything else that is needed. Shy of rounds to shoot.

Efk suggests using the 9mm mags when you swap out calibre.You will have no issue fitting 9mm mags into a 229 made for 40. or 357..

To answer the OP's question, yes, you can convert from DAK to Da/Sa. I was issued a 229 DAK. I hated the DAO, so our armorer converted it to DA/Sa for me. There's a kit available to make this happen, I just don't know where you'd find it.

I was looking at a list of services from Sig Sauer and they will do it for you.I think the cost was about $179.If you go to their website you can find all the info there.

Op...

My bedside gun is a 226 .40 DA/SA... and it's a great gun... however, I would never use it as a CCW platform because of the DA/SA feature.

I'm not sure how familiar you are with DA/SA's but my problem with them is the distance the trigger drops to rear between the 1st DA shot and the following SA shots.

This actually requires me to change my grip on the pistol in order to avoid having way too much finger on the trigger.

If your 229 will be a "carry" gun... I would suggest keeping it DA only and training with it. I know those light SA triggers are nice for plinking and I have no problem with SA only guns for carry, actually still carry my Kimber 1911 on occasion, but it would concern me to carry a pistol that did not have a consistent trigger pull.

Any weight/length of pull can be "trained for" so whether you choose a striker gun, a DA only, or an SA only, is irrelevant and boils down to personal preference but I would avoid going DA/SA on a platform that "if" needed, you'll be grabbing... and using... in a big hurry.

With all that said, if it's not for EDC... modify to your heats content!

Have fun and be safe, the 229 is a fantastic platform.

Tack

Although the change to DA/SA can be done by you, I would recommend you have a SIG Armorer do it. If I were you and are dead set on the SA/DA model, sell yours and get what you want, or offer it up for a trade. The DAK trigger system is a little harder to get used to, but once mastered, is a good system. Good luck with what ever you decide to do :).

You can buy a 9mm conversion barrel and use your .40 mags but don't use it for carry and let your life depend on it. If you do some reading you will find that this is not a 100% setup and will fail many times but is ok for the range. The P229 with a German frame uses a different exchange kit than the newer Exeter frame. Osage County guns has lots of good Sig info on their site and you can learn a lot there.
