Glock 33 to 9mm

[CharlesT]

I am confused when it comes to Glock conversion barrels.

I would like a slightly longer 9mm barrel for my Glock 33 so I can get it threaded.

What exactly do I need?

It should work with just a conversion barrel and 9mm magazine.

There are some differences in the ejector and extractor between Glocks in 9x19 and those in .40S&W and 357 Sig, but I wouldn't worry about those unless it is going to be a defensive gun. Otherwise it should be plenty reliable for range use.

I have a standard length Lone Wolf 9mm conversion barrel. I also have a factory G27 barrel, they both work perfectly in the G33. This http://www.lonewolfdist.com/Detail.aspx?PROD=1005&CAT=241 is their threaded variant.

The 9mm magazine turns out to be a must have, but I was fortunate to run into 2 10 rd G19 magazines for $20, which work fine. A friend of mine has an XD40 that runs a 9mm conversion barrel just fine with 40 S&W magazines, so I was a little bummed.

I used a Lone Wolf 40-9 conversion barrel in my 31 with good results. Just use a 9mm mag, and you should be good. Ive heard some say the extractor and ejector could be a problem, but mine never as much as hick upped with the 9mm barrel in the gun.

Lone Wolf also has threaded barrels. This should work in your 33.

I use a Lone Wolf barrel on my G32 with no problems at all.
The Glock Store has the threaded barrel for yours for $125
