I have one also....
The actual trigger is different and feels better on your finger.
I can tell a difference and like the trigger pull better....a little crisper, reset is nice. Worked perfectly with no issues.
I was a little concerned about the rear site not having white dots. I did shoot it really good. I like the fact it is made to accept after market sites like the Glock's are.
This will replace the G2 in one of my vehicles with it's 3 magazines.
