No, it did not have that extension. And I can see how that would definitely help. That was one of my 2 complaints about it- it was just so short I couldn't find a good grip. So every shot was smacking my hand between the thumb, and/or scraping my finger on the trigger guard. The other thing I disliked was it has such a long hard pull- I suspect that would be for safety reasons. But man it just felt like I was squeezing that trigger forever before it finally fired. I could adapt to that, but the jerk (from no extension) was a deal killer. Now I might have to see if someone has one with the longer aftermarket extension to see how that feels.
Would also like to test out the LC9
