Has any one any experience with the lone wolf conversion barrels for block 23's? I am anticipating buying one with some 9mm magazines instead of buying a Glock 19.  I wanted to see if anyone had any experience with them.

I have used lone wolf barrels but not their conversion barrels the lone wolf barrel I had shot quite well.  I wouldn't hesitate to buy one of their conversions I know they are quite popular.

Wait, is it just a barrel or is it a whole slide? A little confused on this. I don't see how a .40 extractor would work with a 9mm. The only thing I know a .40 with work with is a .357Sig, cause my dad bought a Glock 32 and a Glock 23 barrel to go with it since the case of both rounds are the exact same dimensions.

Works just fine. I have a 9mm barrel for my XD in 357 Sig. I use 9mm mags, but it feeds and extracts great.

Interesting, first I've heard of that.

Look at all the instances there have been of guys accidentally shooting a Glock 19 mag (loaded with 9mm) through their Glock 23 (chambered in .40 S&W).  The extractor is what holds the smaller 9mm casing against the face of the slide allowing the firing pin to hit the primer and set off the round.

I run a Glock 24-C (.40 S&W) and have two spare 9MM Lone Wolf barrels for it. One is extended and threaded, the other is just 9MM Compensated. Never a problem. I like to hoard my .40 S&W ammo, and practice with the cheaper 9MM.

I also am pretty sure you can only go down in caliber conversions so you can take a .40 S&W Glock and convert it to 9mm but not the other way around due to the size of the hole cut into the front of the slide.  Not 100% but thats what I seem to recall when i was looking at getting a .40 barrel for my Glock 34.

It's not recommended as the breachface is wider for the .40 case. The ejectors are also different. Lots of people do it without issue, but I never will.

I just ordered a Lone Wolf 23-to-19 conversion barrel yesterday (black/threaded). I'll let you know what I think in a few weeks after I test it out.

So I sent about 100 rounds down the pipe in the new conversion barrel without a problem. Plus now I'm suppressor ready with the threads.............. I'd call the Lone Wolf conversion a pretty good buy.

I was also thinking about this as I want to make the switch to 9mm from .40. Rather than ditching everything and getting 19s and 17s, I figure the barrel and mags would be a cheaper way to go.

I'm still on the ropes about the .40 to 9mm conversion. I would expect there to be failures to extract or the occasional failure to fire due to the different sized cartridges.

It is also possible for the primer to strike the ejector and cause a discharge

So I took my 40-9 conversion barrel to the range. I purchased  (4) 9mm 15 round magazines to go with it and tried a couple different types of rounds.  While researching before shooting it, I found out that its best to go with a 124 gr round to keep from any malfunctions due to the higher strength ejector.  115 gr rounds will work and most often do, the only rounds I've researched people have issues with is WWB in 115 gr.  I tried Atlanta Arms ammunition in 115 gr, Hornady Critical Duty and 124 gr.  

 

Shot flawlessly with both rounds, did not have any failures or malfunctions what so ever.  Shot very accurately up to 30 yards, just as accurately as my OEM Glock .40 barrel.  

 

Have to say I'm very happy with it, since the intention was to try and stay with a single type of round in our house hand guns since I have two other 9mm for my wife and another home defense handgun.
