As the title says, just picked up a Gen4 22 test fired on 06JAN12. It's got the shiny black finish and the updated ejector. I picked up a G23 in a trade and have been getting back into the 40S&W guns lately. I did a little research on here about the light issue the Gen3s had and was satisfied that the issue was resolved with the Gen4s (and mags). Like all Glocks, it's beautiful . Here are some pics: With some of its' new full size family members... Unfortunately, I won't be able to get to a range for 2 weeks due to work and travel, but when I do I'll let ya'll know how she performs.
