Great....I called Gray Guns to speak with them about their trigger as they had 5 in stock, but they were pretty busy when I called so I offered to e-mail them instead. They said that'd be nice of me, and they'd get back to me ASAP and tell me if their trigger would fit in my P220 properly. Haven't heard back from them, and now I see their trigger is out of stock....figures! Who knew it would be so hard to get a stinking trigger for my Sig! I have one last option for a source...we'll see!
