I recently purchased a California Compliant Sig P229 40S&W that has the Loaded Chamber Indicator on top of the slide and magazine disconnect safety. I wanted the option to convert it to 357 Sig, so I also purchased a 357 Sig barrel directly from Sig Sauer since the website indicated that it will fit a .40 Auto P229. Unfortunately, the replacement barrel does not fit because of the Loaded Chamber Indicator. The 40S&W barrel has a slot to accommodate the Loaded Chamber Indicator while the replacement 357 Sig barrel does not have the slot. I was wondering if anyone knows if the Caliber X-change Kit 357 Sig would work with a California Compliant Sig P229 40SW. I tried calling Sig but it seems they are busy all day. I may just have a gunsmith create a groove on the replacement barrel if that is the best option. I would appreciate any insight. Thank you.
