View Full Version : Glock 23 9mm Conversion issues. (PICS INSIDE)

I've had my Gen3 Glock 23 for Well over a year now. I bought it used, replaced every spring inside it except the mag catch spring. Never had an issue other than some feeding issues that were narrowed down to one (damaged) mag. And the slide stop locking the slide to the rear, due to me pushing it up with my thumbs during fire.

After doing a bit of reading. I purchased a Lone Wolf Distributors 9mm conversion barrel. All the reviews I found spoke of ejection issues, and that the barrel should not be used for defensive purposes. Even if paired with a 9mm extractor. Fine by me. I just wanted a way to cut costs at the range, and a bit of versatility so my GF could shoot it with lighter recoil.

I've run about 200 9mm rounds through the barrel, with only one malfunction. A failure to eject, in the form of a stovepipe. I also ran through another 200 rounds of .40 since purchasing and using the 9mm barrel

Usually my Glock gets a field stripped, wiped down and a bit of oil on the frame rails after every trip to the range. Every few hundred rounds I'll do a complete tear down and clean it out.

This time however, I noticed something odd. I was disassembling the slide when I had difficulty removing the firing pin safety. Usually it comes out easily after the extractor is removed, but this time it was stuck. I pulled it with my fingernails, and noticed it was full of brass shavings. Presumably created from extracting the 9mm rounds with the 40 extractor. Upon further inspection, i found the shavings to be throughout the slide, firing pin channel, extractor plunger channel, and in the frame.

My concern is that the brass shavings will have a negative effect on the firing pin safety, potentially seizing the firing pin safety and making the gun inoperable, or unsafe. Is this a valid concern?

Also, would switching to a 9mm extractor resolve this issue? or is this just the nature of using a conversion barrel?

Another thing, possibly unrelated that I've noticed is damage to my firing pin. I took as good of pictures as I could get. I would also like to know if this is another potential issue, and what may be causing the damage to the firing pin.

Any advice appreciated. Thanks

I am also thinking about getting a 9mm barrel for my glock23. Was wondering do you use the same glock23 magazines?

I have once. It worked, but I picked up a 9mm mag anyway.

I honestly wouldn't worry about it. Have run converstions in G24, G22, G23, and G27 and seen similar shavings but never had any issues.

Okay, that's what I was looking for. I clean it regularly. I just wanted to make sure I wasn't going to cause problems.

Re-assemble it fire 200 rounds of 40, and reinspect. I know that isn't very helpful, but you need to make sure its limited to the 9mm conversion. Please post your findings. My guess is its not limited to the 9mm. Also, keep in mind that it is possible that too much lube could help such debris migrate to the firing pin channel.

I did the 200 rounds of 9. (work put on a range day/shooting competition. My team won 1st place :cool: ) Had similar results.

Next trip to the range it will be fed a steady diet of 40, and inspected.

As far as lube, I use a 50/50 mix of ATF and 10w30. I use a small child’s paint set paintbrush to put a drop or two on each of the frame rail contact points, and a quick run down the rails in the slide. Then I use my finger to put a light coat on the barrel where it wears against the slide. It is possible that I'm using too much and promoting debris collection.

Sounds like you clean you gun on a regular basis? That said the pics show much more crud and grime than I'm used to seeing. May wanna skip the Oil/ATF mis and just go with oil by itself. I've never seen the need to mix ATF with Sythetic Oil when the oil works just fine by itself.

The first time I noticed it was after ~ 500 rounds, mixed 9 and 40 over the course of several range trips.

Usually I just do a quick wipedown after a trip to the range. Every now and then when I'm watching the boob tube I'll do a detail cleaning. That's when I noticed it, actually I didn't think anything of the grime until I had trouble removing the firing pin safety. That's when I noticed the brass shavings.

I have seen the same copper shavings in the firing pin channel of my old G19 - wasn't a conversion, all factory.
I didn't lube in the fp channel, just cleaned it out every time with a q-tip.
