Glock Gen3 Serial Numbers

**FChen17213** · 03-14-12, 21:33

I know Glocks are now in the s prefixes now. I have heard of many Gen3 problems with R prefixes and afterward. We all want to get an earlier Gen3 gun. My question is whether anyone knows what serial number Gen3s started to go bad like Gen4s. I have an earlier one with L prefix that is gtg. However, I am worried that my Pey prefix one is going to be a lemon. It is an rtf2 gun and I specifically got it because I thought that the Rtf guns were before the whole Gen4 and late Gen3 fiasco. Anyone know an approx serial number cutoff?

Anything before M.
P through S are suspect thats like 2010-2011.

I am lucky because I have a 2003 Mint never fired Glock 19 and a 2009 Austrian Proof Marked G19.
My Glock 21SF is a P serial number and its fine...I think the 9mm's from 2010 to 2012 are the ones to look out for.

I recently bought a G19 that has an S prefix and after close to a thousand rounds through it, it's been fine. I've gotten a couple failure to ejects but that was only with cheap, Tula, steel cased ammo. Everything else has fed fine through the gun. I'm assuming it's a luck of the draw thing similar to Kimber 1911's. There are some lemons here and there but I think for the most part they're still pretty solid.

R prefix here- 1,960 trouble free rounds and counting. Ran it through a 2 day Defoor Advanced pistol course with no problems. Love this gun.

SEZ that would fail to ejecto, stovepipe, or send brass back at my face every three or four rounds. It was rare to get through a magazine with no failures, and common to have multiple failures in a single magazine.

I have G34 RSW test date 06-21-11
G26 PZU test date 01-13-11
Both with over 1000 rounds with no problems

I have a NDW Prefix & it is a RTF Series,,the original RTF before they switched. It is after the M prefix,,but it has been a awesome pistol with no problems ! I easily have 5K through the gun !!
