I just picked up my new Gen3 G23. Sweet shooter. I also got the LWD 40-9mm conversion and 357 Sig barrels. It shoot 115gr. 9mm and the 357 with absolutely no problems. I adjusted my grip a little from a Weaver to a Stevens(?) and it made getting back on target a lot faster. Also, I found that advice that the 180g 40 recoil is a little softer than the 165 is true. That's the weight I've decided on for SD. I've been carrying it for three weeks at 2:00 and it doesn't feel as obtrusive as I thought it might. That's where I carried my G26 for the last three years. Don't flame me for the Gen3 that I had to order to get. I know the Gen4 is getting great marks but I'm conservative and want a gun with an established reputation. And I have a box of G26 parts that will fit. Anyhow, it's great. I'm glad to be part of the club now.
