I just converted my glock 27 into a 9mm. I ordered and installed a lone wolf barell. I enjoy shooting my usp 40, but the glock 27 didn't feel comfortable in my hand. I'm hoping converting it to 9mm will help. Anybody else do this conversion? I've read good reviews mostly, but a couple gun shops mentioned possible extraction problems. Lone wolf says just change the barell, use a 9mm glock clip, and you're done. I won't get a chance to shoot for a while, but I've loaded several clips and cycled them through with no problems. Not the same as shooting though. So...anybody convert their glock?
 
Wouldn't it have been slightly cheaper to sell the 27 and buy a 26?

but then you couldnt swap back and forth between the 9 and 40 at will.... honestly I have thought about it... but that is due to the great price on a used 27.
 
What's done is done. I like having .40 and .9mm capability in one gun, especially. Since I have a usp .40 and plenty of .40 ammo.
 
I'm just looking for reliability feedback from people who have done a lone wolf conversion, not looking to sell my 27.
 
I have a .40 caliber Model 23. I purchased the Lone Wolf 9mm conversion barrel. All I did was swap in the barrel like they said, along with a 9mm magazine. I bought the barrel for $99 and four new Glock factory mags @ $20 each. For $179, it is like having 2 guns. Last time I checked, I couldn't find a Glock 9mm for $179.

The 9mm setup shoots perfectly. I've fired 6 matches with it (50 rounds each) and I had only one misfeed. Not really sure why it misfed, but it only did it once and hasn't done it again since.

I'm a bit surprised that I didn't have to swap out the recoil spring, but it sure is working great just the way it is.

I think you'll enjoy your new barrel. The 9mm is much less "jumpy" in your hands than the .40 caliber.

Good luck!
 
I've done the conversion on a Glock 22 to 9mm with their compensated barrel. It works well. It doesn't have extraction problems but it just barely ejects the brass. I use Glock 17 mags in it. I think they are good for plinking and such but I don't know that I'd trust it for defensive purposes.
 
So if the only difference after the conversion is the extractor, what's involved in getting a new extractor in there. I'm gonna be using it as a 9mm full time since I have a usp .40 anyway.
 
There could be a problem with the .40 extractor - or also with a new 9mm extractor due to breech face differences. You might also have to change the spring loaded bearing for the extractor plunger for a 9mm unit.
You will also probably have to change the recoil spring assembly for a 9mm as the .40 unit is quite a bit heavier and the 9mm rounds may not enough energy to overcome the heavier spring.
All in all these conversions have not worked out for a lot of people. Some have had luck and have had guns that worked after a fashion... but others have given up on the project. Much better to buy a 9mm Glock than to go through all the effort to build a (marginally reliable?) 9mm conversion.
 
Swapping the extractors is easy....junt around online for a video showing a full slide strip to see how to do it. I broke mine down with no instruction....Glocks are that easy to work on. If you want to leave it as a 9mm, you should also swap the ejector housing...which is pretty simple too. I've converted a G24, G23, & G27 all with positive results.
 
1) The 40 SW and 9MM recoil springs are the same (in my testing they probably shouldn't be, but they are).

2) The extractors are slightly different but the hooks are the same depth and distance from the breech face. The only difference is the angle of the hook face.

3) The ejectors are different - just look at them.

4) The firing pins (strikers) are different.

5) The breech face width is different.

6) The extractor "spring loaded bearing" is the same on all the small frame guns. The only difference is between the "loaded chamber indicator" extractor and the "old/original style".

If you really want a Glock 26, buy one. I would never trust this type of conversion for anything serious. If you are thinking of practicing with 9MM and carrying 40SW I think you are making a mistake. The recoil characteristics are quite different between the two and you will not get proper feedback for good shot to shot performance.

Does this go for the other conversions as well, G22 to 9mm and G20 to 45 acp, in particular?

I have a G22 I was thinking of converting to 9mm and I was thinking of getting a G20 because I could convert it to 45acp, but I don't want anything that is not reliable.
 
In my approx fifteen years of experience with more than two dozen Glocks of various types I have concluded than when you venture outside of Glock design parameters you are asking for reliability issues.

This does not really matter if you are only playing at the range.

Remember, Glocks (and many other common weapons) were originally designed for military contracts. Military weapons are designed to be very reliable with issue ammo which meets a tight performance spec.

What I said before - do whatever you want at the range - stay with strict factory specs if it might really matter.
 
I have the Lone Wolf 9mm barrels for my 27 and 23. I have never had a problem with either gun. All I do is swap the barrel and the mag. I do however only carry the guns with the 40 cal barrels.
