Well even after reading all the negative post on here, I got one anyway. The first outing with it shooting WWB 165gr, I had several FTF with the last round in the mag, several differant mags. So i went home feeling sorry for my self. I decided to try a heavier bullet, so I got WWB 180gr, back to the range I go.
Everything went well, or so I thought. I was down to the last 50 or so rounds and the problems started. I was realy bummin at this point, and i wasnt going to ask for help here, I was for warned. But I did get to searching this site for the answers. I read that maybe a 22lb. recoil spring would help, so I ordered a steel guide rod and spring.
The next range trip was short. I didnt waste ammo having the same problems. I started looking at the mags, of the five I was useing two of them had a 2 on it, the other three had 1.
I took apart a 1 and a 2 mag apart to see what the dif was, they were both the same. So scratching my head, I decided to call Glock.
I was told that the 2 mags should have a 10 coil spring. Click, there is the problem. Glock said he would send me two springs, I jokenly said i needed ten of them, he laughed and took my info.Two days later I got the springs, (he sent five. thanks).
So I loaded up and headed for the range. I took 200 rounds, hoping the problem was fixed. I loaded five rounds in five mags. No FTF…
Goody for me. I was feeling pretty good so I put the 22lb recoil spring back just to test my luck. Five mags loaded the same, agian no FTF… So I burned thru the 200 rounds loading the mags with five rounds each. I couldnt make the gun fail. so I went home happy.
I want to be able to carry this gun, and I have since fired 400 more rounds, for a total of 600.
So after all of that, would you guys trust it?
If you can fire 1000 to 2000 rounds through it without a malfunction then I’d trust it.
Thanks for the report
I was planning on another 500 this W/E thanks.
Mook, Im glad you could use the info.
I hope you can trust your weapon. One more person carrying concealed. 
As mentioned before I would fire at least 1-2k through it without any problems before I would not have to think twice if I pulled it out to defend my life. As with Murphy’s Law anything can and will happen so you also need to train on how to correct things if said problem(s) do arise if you don’t already do so. This is your safety net in some sense.
My biggest thing would be why after a lot of negative feeback would you go out and buy a weapon that is not as reliable as say the 19/17’s? That to me is my biggest concern. I feel that you were rolling the dice a lot more than with the beforementioned models. I guess to each their own and I’m not trying to pick on you here rather than being more curious as to the reasoning behind said choice.
Overall go out and practice and train as much as you can to be as proficient with your weapon as you can. You never know when/if that day will ever come when you have to call on those skills to save your or your families lives. Stay safe.
You need to put 1k rounds of your carry ammo, not just fmj target ammo.
Jack,
I do have a 19, and your right, it is a great weapon. I have put prolly 2500 rnds thru it without one failure.
That has been my carry weapon. I guess I wanted to go to a larger bullet, that is why I got the 23. Thanks for your reply.
It sounds fine. Some guns just need a little break-in.
This. Several detectives at my agencies want the heavier .40 cal and carry the G23 under their jackets. They love the weapon. I am considering moving up from my G27 to the G23 for off duty carry.

Did you consider changing ammo before going through all the other things? I have owned to date 3 Glock 23’s and many other Glocks of other calibers and had never experienced the problems you are describing.
For that matter a Glock is the only gun I will carry with out doing the hundreds of rounds break in that I would do with other guns (if I had to and I have).
I am not a Glock stock holder or married to the Glock family but I still think that Glocks are the best weapons out there at least for me and believe me I have shot all of the other ones extensively.
Now if I could not get a Glock I would not hesitate to go with an M&P in a minute.
I failed to mention that differant ammo was used in the mix, both FMJ and JHP. both with the same results, untill I changed the mag springs.
this a new or used gun? if it’s brand new it should easily run through 2k+ with no problems. yeah the 40 cal glocks are “less reliable” than the 9mm’s, but they should still be incredibly reliable. keep your mag springs and recoil spring changed at a regular interval (2500 or so on the recoil, mags vary… if you load them to less than capacity the springs will last longer)
The spring and rod you bought is not required in a properly functioning gun. I have no use for them. If the gun wasn’t running with the OEM captured spring, you’ve only put a band-aid on an underlying problem.
WWB is marginal ammo, but if the gun will run with it (in OEM config), bonus.
The mags aren’t your problem, but the revised spring is best.
Short: If the gun didn’t run out of the box, send it back.
Didnt Glock go to a stronger recoil spring in the Gen 4 23’s?
How can it be a band-aid for me putting in a stronger spring?
My first gun ever was a Glock 23, then I got rid of it and bought a Sigpro2340, got rid of that for another Glock 23 (which I have since sold).
I’ve shot several thousand rounds through two different Glock 23’s and NEVER had a single ftf, fte, misfire, stovepipe, or any sort of malfunction. I’m surprised you had so many…
While this would be ideal, it is just not going to happen for 99.9% of shooters out there. Telling someone to put $500-$1000 of ammor through a $475 pistol before they use it will be seen as an extreme my most. Man made creations fail, and no amount of proofing of an individual sample deem it 100% reliable.
Most carry ammo seems to be around a buck a round.
Are there many (any) of you sending $1000 worth of defensive loads through your handguns before you decide to carry that load?
I test new loads out before deciding to carry them, but it’s never been quite that high a volume. That’s simply excessive for most of us having to pay out of pocket.
Did you buy this used?
Put the OEM recoil spring back in it, rebuild those mags and you should be good to go.
The problem with the heavier recoil spring is you just increased the slide cycle speed and made it that much harder for the magazine to keep up with it.
That would be the last thing I would try for feeding issues from the bottom rounds in a mag.
