Hello all...ive been reading this forum for a few months and finally got registered...great forum, so much info here...sorry for this being my 1st post...onto my problem(s)... I got a G23, used, in great shape about 5 months ago...shot about 300 rds thru it, never had 1 problem or malfunction...i field strip and clean after every range trip and detail strip and clean the firing pin channel every other trip. I came from the range the other day, it was detail strip time...and i found this: I was horrified, i dont know how it happened...so i called Glock (even tho i live 10 min from Smryna) i called them and the armorer told me he couldnt send me a replacement part because it was a liability part and pointed me to OMB Express....so i ordered the sleeve, $2.40 shipped, not bad....All is well with the G23 now. However, i also have a G17, and just being curious, i took it down and found the exact same cracked spacer sleeve...cracked in the same spot and everything! Ordered a new one and its fine now. 2 questions: Anybody know how this is happening? Also, should i have just driven the pistol to Glock and let them look at it? if so, would it have been a free fix? Thx so much!
