Just don't decock it and you'll have an SAO P220.
In trying to research this, I read where folks are doing this on DA/SA Sigs. Even the thought of it increased my blood pressure. More power to anyone who carries their Sig this way, but I'd be worried about a ND. My nervousness probably has more to do with actually seeing the hammer back and thinking "no external safety" than it is in in basis of fact, but I'd by lying if I didn't say it set my heart to racing.
I may be able to go DAK. I'm shooting an XD in competition, but I took my Compact out to shoot this last weekend as it's my EDC, and going from DA to SA threw me.
I know the remedy is to just shoot more, but I'd like to narrow my manual of arms.
