I've read most posts on this site, and have some additional questions. My wife got me a G22 for Christmas ..yeah, she's nice Anyway, is there any kind of break in suggestions on a new Glock? Went through 50 rds. on Chrismas and like how if feels. I've never claimed to be a great show, but was hitting center body mass from 20 yds...med group no prob. Where I work, we carry a G23 I believe...the slightly smaller .40. Anywhere to buy the 17 rd. mags?..New? How can I tell what gen mine is? date of manufacture is July I believe. What are the differences? I'd like to upgrade to night sights...recommendations? Anyway, great site...look forward to wasting many sleepless hours here. Thanks!
