Ok, I just picked up a police trade in glock 21 2nd gen with a serial of YA8XX and the US prefix at the very end...

is in great shape other than i think they never cleaned it and came with bright TRU DOT night sights and what feels like a 3.5lb trigger. I have owned several other glocks with the factory HEAVY triggers and this one feels nice and light which is a good thing since i had planned on ordering a new connector and trigger spring to bring it to the 3.5lb mark and this just saved me $20...

anyway was never really interestd in glock history since they are "tupperware" pistols, but my interest in this pistol was raised when my dealer went to enter the gun into his system yesterday (he uses an online automated inventory sytem for book keeping and it checks against several databases) ... anyway he kept getting an invalid serial back from the system on this gun (all numbers match including the barrel serial)... another guy was picking up a gen 2 G19 and that serial came back good... anyway this was a police trade in, so wondering if that had anything to do with not being in the "civilian" system....

any help with a serial background on glocks would be helpful.. I have already been to glocktalk and several other sites on the web with glock serial number info and none have the YA prefix listed (even the glockhaus site with automated lookup)..

worst case is i will give glock a call on monday.

thanks for the help in advance.

Can't help you with a manufacture date, but since it has "US" at the end, that does mean it was imported from Austria

As a rule I never go to GT, but I went anyway and found the range in which your serial prefix YA**** would've occurred.

It's about 20-25 lines from the bottom of the post- http://www.glocktalk.com/forums/showpost.php?p=19477615&postcount=2 -


XV**** G-17 - 1991-11-01
XW**** G-17 2.0 1991-11-01 AS, 5lb trigger
YA**** would fit here
YE986* G-17 - 0000-00-00
YK**** G-17 2.0 1991-12-01
YL**** G-17 - 1991-12-01

- and puts your gun's date of manufacture in the November 1, 1991 to December 1, 1991 range.

Since the Glock 21 was introduced in mid-1990, it would appear that you have a very early production gen 2 G21.

sorry for late reply...


turned out was a special order for york PD in york nebraska.... hence the unique serial...


they came with factory 5lb triggers , but mine appears to have been modded with at some point by the LEO carrying it to drop it to 3 lbs.

i already upgraded the gun by added grip plug, ghost connector and trigger spring and accumatch SS barrel . have an ghost extended slide stop on order and should be good to go.

great gun and works great as well.
