Need help identify a P229 22LR conversion kit

I recently bought this kit and was wondering if it's the correct kit for the P229R? The box says P229R, but looking at the other railed kits, those all have shorter hoods/dust covers. Don't have a P229 yet, so would like to hear from experts here. TIA.

The top slide in the photo is for the non-railed 229 or the 228. It has a slightly longer lower shroud because the 228 and early non-railed 229’s had a shorter frame. There is no conversion slide that is marked 228. A conversion slide for a railed 229 will be the same dimensions as the middle 226 marked slide. In fact, the slides are identical, only the rollmarks are different. However, the barrels for the 226 and 228/9 are different. The locking lugs are different (clearly shown in the photo).

You can run the shorter 229 railed slide on a 228 or non-railed 229, you will just have a small gap between the frame and slide at the bottom. I run this setup myself. Works fine. I’m not 100 percent sure, but I believe the longer 228/229 non-railed slide will work on a railed 229, you will just have that extra chin length that is not necessary. But I believe that there is enough clearance in the frame guide rod area that it would work. Perhaps someone else can advise if they have tried it.

Hope that helps.

OP,
The P220 & P226 22LR Cal X Change slides are identical w/ the exception of the firing pin stop in the aft end of the slides.
(P226 being thinner of the 2)

The P228/229 22LR Cal X Change slides are interchangeable between both frames.

The P229R 22LR Cal X Change slide's "chin" is shorter than the P228/229 slide chin because of the lengthened dust cover of the 229R frame.

P226 & P229 magazine bodies are identical w/ exception of the P229's base having .300" legs to fit the shorter frame's magwell length.

Thank you guys for the confirmation.


Left to right - P229, P226, P220.


Top to bottom - P229, P226, P220.
P229 has different slide cutouts than P226 and P220. The firing pin stops are thicker on the P229 and P220. The stops appear to be the same size on P229 and P220.





All 3 models use the same springs. P229 guide rod is longest, and P226 and P220 rods are identical.


Top to bottom - P229T, P229, P226T, P220T.




Takedown lever cutout - Top P226, bottom P229. Looked to be the same size to my naked eyes.


Slide lock - same size

Although the cutouts for the slide lock appear to be the same size, I could not lock the P229 slide back. Not sure if the longer hood or something else in the front was preventing the slide from going all the way back.


Disconnector cutout? Top P229, bottom P226


P229 22LR vs P226 9mm Legion


My guess is that P226 22LR kit should work on the P220 with the appropriate mag. It should also work on the railed P229 with the P229 22LR barrel. The mag will stick out due to the shorter base plate. Unless a shorter firing pin stop would cause it not to function properly?

This is an interesting twist. I have a P226 .22LR cal-x kit. To use it on a 229-1 or 229 in .40/.357, I just need the barrel, guide rod, and magazine. Is that what I am reading here?

The question remains: does the shorter firing pin stop on the P226 slide make a difference when placing it on a P229 frame?

Only 1 way to find out.
I don't have a P229 yet.

The P226 22LR mag will work in the P229, but it will stick out due to the shorter base plate.

Not sure what a shorter firing pin stop would do though. A friend of mine used a P220 22LR kit on his P226, and the thicker firing pin stop would cause it not to fire. He ended up filing it down a bit and it's been working for him flawlessly for years now.

OP,
Install the P228/229 22 Cal X Change top end assy on your P226 frame w/o locking the slide stop into the slide.
The longer "CHIN" of the P228/229 slide prevents the slide stop from performing it's function properly.

Allow the 228/229 slide to go into battery on your P226 frame.
(reply w/ your issue & I'll enlighten you how to remove the slide)

There is more to the equation than the thicker firing pin stops in P220 & P228/229 slides.

The Bbl locking lugs are marked,220,226,29....for a reason.

The slide's trigger bar disconnect cut is not in the same ball park as designed to interchange a p228/229 to the P220/226.

Been there...25+ years ago.
