I have quite a few guns from quite a few manufacturers, but I do try to keep to one action type. My basic rule is that every pull of the trigger must be the same. SA, fine. DAO, fine. Striker fired, fine. DA/SA, not fine. It's simply a training thing for me.
Of course, like every rule there are exceptions. I'm being very tempted right now with a tax rebate check inbound and those smoking hot deals on Sig P6 that I may have to make one exception.
