Started production in 2000, shot it until CO came out due to eyes going south and I didn't want to futz with Open.
I do miss the planning of the 10 rounds, found my reloading skills have declined as I do so few of them now. I see faster shooters, mostly the kids that come in blazing away like open shooters - more of the spray and pray mentality that we all get when we have more than 8-10 rounds, LOL! That being said, shooting on the move is now a solid part of my technique now that I have more rounds to play with.
Open shooters I've seen take a bit to get it as the gun actually moves compared to their heavier open pistols. Looks like everyone and their brother has come to play in the division, more players, better competition. Heavier guns coming in - not sure how that plays out as I've stayed with Glock. Too much invested in the platform to change unless I were to win something different. Heavier guns may be a fad or it may be here for years and set a new tone. Who is to say.
Larger mags, I've seen a host of different types, not sure if all are legal, but with the many different guns that are out there, what looks huge on a mag holster may be solid for whatever gun is being run, some of which I've not seen.
Bottom line it has been good for the sport.
