The P226 is one of the most modular pistols offered by Sig Sauer, only the P250 offers more variety. Caliber X-Change kits allow the pistol to be converted from its native caliber to a different caliber. The Caliber X-Change kit includes: Slide with night sights Barrel One 15rd magazine (call prior to purchase if you need a 10rd mag for residents of states with capacity limits) Recoil spring and guide Installation of a Caliber X-Change kit is simple and only takes a few seconds (you basically field strip the pistol and install the conversion slide). To install, remove the magazine and make sure the pistol is unloaded and clear. Lock the slide back and rotate the takedown lever down approx 90 degrees. Pull back on the slide and press the slide stop and ease the slide forward off of the frame. Take the new slide, fully assembled with barrel, guide rod, and recoil spring, and mount it on the frame. Lock the slide back with the slide stop and rotate the takedown lever back to its original position. The conversion swap is complete. Please note that this kit is not compatible with Sig Sauer's X5 and X6 pistols. Caliber X-Change kits do not require a FFL for shipment. We can ship right to your address.

Better than expected
Converted my 40 to 9mm at the range and compared all the differences, recoil, accuracy shootability. Naturally, less recoil and easy to shoot. Excellent accuracy. I now have a P226 in 40 S&W and 9mm. If you're "on the fence" take the leap.
BTW, OCG was easy to work with, with quick shipping.

I bought this kit to convert my Sig P226 .22 to 9mm and it is perfect. I saved a couple hundred bucks going this route instead of buying a 9mm and converting to .22.

Product Questions

Hi, I have a few questions on this item. Is this the same as the one Sig sells? Why isn’t the spring red like Sig’s? Do these conversion kits have to be shipped to an FFL dealer or can they ship directly to home?

Referenced product: CALX-226-9-BSS

This should be the same kit that Sig sells. The photos have been updated and previously showed the incorrect kit. The spring is red. These can ship directly to you and do not need to go to a FFL.
