I am new to the forums, and a new CHL holder and handgun owner.
After a 9 month selection process (as time would allow, and access to handguns) I chose the gen4 Glock 19 after originally not liking the gen3 Glock 19. I had only shot about 100rds from any pistol (Baretta) and therefore was very much an 'open book' when it came to my selection.
That being said I was aware in november when I chose the gen4 19 that there might be some spring issues, but it had shot the best for me every time I used it so selected it anyway and decided to track any issues I would have by noting the specifics of the load I was using and the number of rounds fired from each; along with rounds shot in between cleanings, number of rounds fired before another error and so forth.
From 11/07/2010 until today I have shot 2630 rounds with 11 combined errors (either failure to feed (FtF) or failure to eject (FtE), giving me a 0.418% error.
Of the 11 FtF/FtE (6 FtF & 5 FtE) errors, 6 came from the 300 rounds of Monarch 115gr brass ammunition, or 2.0% (shot over different sessions)
It is also worth noting that 6 of those errors came between 11/07/2010 and 12/01/2010 (1,000 rounds shot in that period), including one FtE from Winchester 124gr NATO (50rds shot, 2.0% error), which may suggest user error on part of the grip as after the 12/01/2010 range session I notated that I learned and started practicing a new (and proper) grip starting on 12/10/2010.
My longest period and most rounds without error was between 12/10/2010 and 03/09/2011. The gun had intentionally not been cleaned since after the 12/01/2010 session and would not until error occurred again. A total of 1,430 rounds over 8 sessions.
Finally on 03/11/2011 there was 1 FtE after 100 Winchester 115gr white box and 2 FtE and 2 FtF from 50 rounds of Monarch 115gr brass.
I decided to go ahead and call Glock for the 04 spring anyway, just to have and so I can get a comparison going.
On a side note, the gentleman at Glock was very helpful and did ask me about the type of ammo I had used and how many errors I experienced. I was pleased to hear him say he was surprised about how few errors I had experienced over that many rounds and complimented my grip.
I don't know if this will be of any use to anyone, but I did fire 7 different factory loads over the period mentioned and could go into a bit more detail if anyone is interested. I had not seen anything posted with detailed notes and tracking of their range sessions like this and wanted to share.
I welcome any questions and/or comments.
p.s. Another reason I posted it is because I do not have any real, hard frame of reference as to what a typical error rate is with any handgun, as I have never shot over 2,600 rounds from the same weapon and kept any sort of reporting while doing it. I would be very interested in hearing any other such results from the same or different guns, with the same or different loads.
