My issue Glock 22 packed it in last week, cracked slide on the right side near the front of the ejection port. Was issued new in 2000, and I have just short of 32,000 rounds, all factory, majority WinClean 165 gr.. Glock Rep up here said he's seen a few in .40 and 9 break in the same spot but usually higher round counts. Have a brand new one, but she's not the same. Can anyone advise on similar problems? At least she lasted 3 times longer than my Beretta .
