Glock 22 9mm conversion barrel

Just got a Lone Wolf Glock 22 9mm conversion barrel about a week ago and finally got to the range and try it out. I fired 150 rounds of ammo using Glock 17 mags and 100 rounds through the Glock 22 mags (because I heard 9mm will function through them). The ammunition consisted of Blazer aluminum, WWB 115 grain, Rem Golden Sabers 124gr and Rem FMJ 124 gr. The gun was flawless with the GL 17 mags, no malfunctions at all. Only had two malfunctions with the Glock 22 mag, both failure to feeds. The failures with the GL 22 mags happened when I tried to fire one handed with a loose grip, went back to flawless when I used two hands again. Anyone else have a conversion barrel for the GL 22? Same results?

Yeah I pretty much had the same experience. I got tired of changing barrels and bought a 17. It was fun while I had it though. Enjoy yours.

For best functioning I would suggest the use of 9MM magazines. Their are some slight differences in the 9mm and 40 S&W magazines,the feed lips on the 40 S&W are .010 wider than the 9 mm magazines. While they may work after a fashion you will get a much more harmonious out come with the 9 mm magazines when using your conversion barrel.

I used G17 mags and found the G22/LW40-9 combo to be very accurate and reliable.

This makes sense. The .40 caliber breech is only a millimeter wider than the 9mm breech face.

I noticed the same thing with my Glock 27. No failures to feed using the G26 mags with the 40-9 conversion barrel, but a few ftf's using 9mm ammo in the G27 mags.

Agreed. I heard you could use the .40 mags too, but didn't even bother. When I ordered my LWD 40-9 barrel from Cheaper Than Dirt I just went ahead and ordered a couple Glock 9mm mags to go along with it. One 17 rounder and and one 10 rounder. Works great, no problems.

Apparently, some of you have experience with 40/9 conversions.

I have been looking at 40/9 conversions for target practice. Storm Lake offers a machined stainless steel barrel that is OEM length and one that is 1/2" longer, whether you look at barrels for the G22 or the G27. I don't know if that extra 1/2" really makes any difference.

I have seen discussion regarding the use of 115 gr. or "low power" 9mm ammo, since the slides on the .40 cal pistols are thicker and heavier, supposedly, necessitating the use of moderate to hot loads for positive cycling. The extra 1/2" *might* make a difference in that regard, keeping the pressure on the slide a smidge longer.

I want either a G17 or a G34, but for now, I could get happy with allowing the ammo savings to cover the cost of the barrel and a couple of mags.

Aside from stainless steel, etc., are there really any notable differences (pros / cons) between the Lone Wolf, KKM, and Storm Lake conversions?

I only wanted to try the Glock 22 mags because I heard they would work, good info to know, but I will use the Glock 17 mags exclusively from this point on as I have 6 of them that I use with my Glock 19. Man that is a lot of "Glock" in one sentance. LOL

I have a LW 40-9mm barrel for my G22. With 9mm mags, I have no problems.

+1
I would add that if you use an extended mag in a short gun,
and pull on the extended part of the mag, even the right caliber mag can FTF.

If you use an extended mag in a shorter gun.
Recommend using a sleeve like XGrip.

Good Luck.
