Just going off the pictures that Sig has on their storefront, it appears that the sights have the capability to be adjusted. Any pros want to confirm or deny?
It's funny because I'm in a similar situation: P226 .22lr + 9mm Xchange kit OR CZ SP-01 Shadow + .22lr Kadet kit
Starting to lean towards the CZ just because I've had a chance to handle it and the grip feels great
