Swapping slides between a Sig P228 and P229?

[himurax13]

Hello, I was wondering if it would be okay to use a Sig P228 receiver with a P229 slide, railed or non railed. Would it work with a 9mm conversion barrel on a .40 S&W slide?

Also, is it okay to use a Sig P229 Receiver with a P228 slide?

My friend has both but we never thought of trying that. Why would you want to in the first place?

The 228's slide was designed to shoot 9mm rounds. The 229 was designed to take 9mm, .40 S&W and .357 SIG. As I recall the 229 slide is a milled steel receiver as opposed to the 228's folded steel. I might be wrong but this is just what I remember reading on the CG forums.


In answer to your question: If you shoot 9mm, I guess you could use either one, if you're shootin .40 S&W use the 229.

Well I planned on buying a few 229's and 226's over the next year in .40 S&W or .357 sig. I was going to convert them all to 9mm for the lower cost and lower recoil. I also wanted the ability to use .40 S&W or .357 sig at a later date and for those I would only use the 229 frames only.

Also is it OK to switch slides between 229's with DAK or SRT trigger setups?

Holey crap, a few 229's and 226's??

If you don't mind voiding the warranty, go ahead, but I wouldn't if I were you. I'd talk to a gunsmith first, because even though they may fit, there might be some really hard to see differences in tolerances that would cause some problems later on.

I only own a 228 and I would NEVER be swapping slides like that.

SIG introduced the steel framed P229 in .40S&W/.327SIG because the alloy frame P228 frame could not take the pressure of the .40S&W/.357SIG cartridge.

So, converting a P228 to shoot .40S&W is not adviseable.

The 229 frame also comes in aluminum, even when chambered in .40 or .357sig.

I have no intentions of doing that. I was contemplating on using a .40 slide with a 9mm conversion barrel.

You know, so that way I don't have to reload. Besides, ever Sig I own is used anyways so I doubt that I have any sort of warranty.
