I'm seeking knowledge and I'm new to the SIG brand and this forum. I was lucky to purchase a used P220 (Carry) but found out about the P227 SAS (Carry). My question is what other configurations do the 227 come in and is there a difference? Any literature online would be helpful. Thank you.

I was looking recently at SIG s website. Looks like the 227 is not listed anymore.

227 is dead from new production. you can find carry, full size and TB versions. with minor variations like the SAS, equinox, elite, etc.

P220 single stack
P227 double stack
