Product Questions

Do you know when you will get the Sig P226 RX X-change Kit back in?Also, I am not exempt, so can you take out the magazine, block it, or swap with a ten round magazine and ship to California?

We don't have a firm ETA from Sig. We will be getting some Legion CALX kits in this week though.

I have a p226 scorpion model with the loaded chamber indicator on the slide which seems to be preventing me from getting an optic cut. If I purchase this slide can I get it the same desert tan color as my scorpion? Thank you for your time.

Sig Sauer does not offer the CALX kits in any finish but the Nitron (black) finish. The Scorpion model is finished in Cerakote. You may be able to send the slide to a company that applies Cerakote for coating.

We're still waiting for information from Sig. We last received a shipment early in the year and we sent a purchase order to Sig in March. We have no ETA despite the long duration since the order was sent to them.

Rate the answer?
Is it possible to switch the magazine to a 10-round CA compliant, and have it shipped to CA?Also, any update on when this might be in stock?

We don't have a firm ETA but hope to have these back in stock in the next 2 to 4 weeks. We can swap the magazine and charge $10 for the swap. The order needs to be placed by phone because our website won't allow the kit to be ordered with a CA shipping address due to mag capacity.

Rate the answer?
I asked a question yesterday and realized it may not have been clear. I was curious if the contrast cut Sig P226 RX 9mm caliber exchange kit could be shipped to California with a 10rd magazine, or just with the magazine taken out of it. Thanks!

We can ship to CA. We'll need you to order by phone. We can pull the mag or swap to a 10rd magazine for an extra $10 (if the mag is in stock).
