Just want to check my info if it is correct. I have a 2005 p229 in 40sw, german frame no rail. In order for me to use 9mm, i have to find a conversion 9mm barrel, correct? A drop in p229 9mm won’t work?

Does anyone makes a threaded conversion 9mm barrel out there?

Thanks.

Here is a link to Barsto. Vey high quality. I have a 9mm conversion barrel for my P229 40 s&w. I purchased a drop in. Fit with no issues.

So any p229 (not the newer -1) barrel would fit in the 40sw 229?

I would recommend calling them. My 229 is at least 15 years old.

I just re read your post. Sounds like we both have the same vintage 229. Should work fine.

Factory 9mm barrel will not work, only conversion barrels will. Slide sizes are different.
I have used Barsto and recommend.

Does the age of the p229 matters? This one in question is early 2000 germany frame.

First, the 9mm barrels have a smaller outside diameter. So the simple answer is no, they will obviously not work.

Here is some other info regarding the 228/229:

Here's the facts which I have...

The 228 and the original 229/9 (not the 229-1) have the same barrel specs.

The new 229-1 and the 229/40/357 have the same lug specs. However, the 229/40/357 barrel is larger in diameter. And wider barrel hood extension.
The 229-1 barrel is the same diameter as the 228 and 229/9.
(This allows you to put a 229-1 barrel in a 228, 229/9 slide and have the proper insert when using a 229-1, 229/40/357 frame.

The difference is the feed ramp on the 228, 229/9 is longer than the 229-1, 229/40/357.

Now to the locking inserts:

The 228 and the original 229/9 have the same insert.

The 229-1 and the 229/40/357 have the same insert.

The difference is the 229-1, 229/40/357 is taller then the 228, 229/9.

So, all the slides will fit onto a frame which has the shorter insert.
However, the slides from a 228 and 229/9 will not fit onto a frame with the taller insert. As the feed ramp will hit the insert and stop it from sliding completely onto the frame.

Now to the frames:

The 228 and the 229/9 are the same.
The 229-1 and the 229/40/357 are the same.

The only difference is the width in which the magwell is cut. The 229-1, 229/40/357 being wider to accept the wider stepped mags.
The slimmer mags will fit and function in the wider cut frame, but they will be a little loose.

** there are some exceptions out there (like 12131's 228ST) which doesn't fit the facts above. As the 228ST uses the same frame as the 229ST, which has the wider magwell. And should have the shorter insert.

*** this information doesn't include the newer 'long extractor' slides. They should have all the same specs as the 229/40/357, but I don't own any of these for comparison

**** the 229-1 slide has a different installed barrel height then the 228. So this will cause some fitting issues. Details are at the end of the linked thread below. There's a difference of .03

P229-1 slide ~.20
P228 slide .23

Here's a couple measurements for comparison:

228 barrel is .831 hood to feed ramp lip
229-1, 229/40/357 barrel is .780 hood to feed ramp lip

228 locking block is .828 tall .708 short feed ramp height
229/40/357 locking block is .828 tall .735 short feed ramp height

228, 229-1 barrel diameter is .530
229/40/357 barrel diameter is .550

There are pictures posted by 12131 towards the end of page 2.

Thanks for all the tech spec!

Ok. I will keep an eye out on bar-sto for any sales. Do i need to change the recoil spring as well?
