I checked out the new M2 today at the LGS ($589).... I thought the trigger was quite improved compared to the original, which was already excellent. They change the mag release to the more conventional "button" style, although I prefer the paddle release. Those were the main differences I noticed. Thinking about going back there to do side by side comparison. Might just pick it up... Since Walther discontinued the "gen-1" in the U.S. only after 2 years of production they could become more collectible here. Some dude is selling one for over $1K on GB. Yikes.
