"this barrel works great i use it in my glock 22 so try it i think you'll like it.and if you want a more powerful caliber then get a 357 sig lone wolf barrel then you will have 3 guns in 1. your glock 22 is a 40S&W then if you buy this then you also have a 9mm and finally you could buy a 357 sig barrel.that's what amazing about the glock why buy 3 guns when 1 gun does it all."

"I just got mine last week and so far I've put 300+ or so bullets through it, without a failure. Great product fit my older G22 pistol great, I like the option of switching calibers in case 40 s&w is not available. Bottom line if you own a G22 and you would like to be able to use more common caliber like 9mm this is a must. Spend the money you'll be glad you did !"

"Great barrel. Now this is help for all of you reading this wondering if you should buy it. I had to use G-17 glock Mags for this to work great. You will see forums on using G-22 mags but it WILL jam with them. I fired 200 rounds today without one jam. The ejector does kind of change the brass trajectory but replacement is NOT neccessary. GET G-17 MAGS if you want a reliable shooter."

"The barrel shoots great, but the extractor on my G22 had problems with the 9mm cases. I had several jams (about one per clip). It was worse with the .40 clips."

"I love this barrel. I went to the range and fired 400 rounds through this barrel with no problems. I hit the target dead center with very tight groups. The owner of the range indicated that using this barrel would terminate my warranty of my G22. He does sell guns so he may have his own agenda."

"Great barrel. Have new version Glock 22 with low use. Put the 9mm barrel in and used Glock 17 magazines. Fed factory ammo without a problem. Did have a few failure to feeds with reloads, but I don't expect perfection with reloads. I would highly recommend this barrel and G17 mags to get double duty from your Glock 22!"

"This is a great barrel for my glock 22. That being said, I bought the glock 17 mags because I heard of a lot of ejector problems. I still get from 1 to three jams with each magazine. I am going to buy an 9mm ejector and see if this will clear up the problem. I also have the 357 Sig barrel and no problems at all."

"I was a little skeptical at first but I read a lot of reviews online & watched that guy on youtube.com who bought one & tested it... so I decided to try one & see. It worked perfectly in my Glock 22, just put in the Lone Wolf conversion barrel & use 9mm magazines & I didn't change anything else.... no jams or misfires of any kind. It shoots point of aim and hits the bullseye dead center. The barrel is heavier than the Glock barrel & makes the gun muzzle heavy,that helps recoil. My only complaint is that I don't care for the wolf logo on the top."

"I bought the 357 SIG conversion barrel for my GLOCK Model 22 and was so impressed that I bought this 9mm. I found the advice of the other reviewers to be very helpful and bought the GLOCK 17 9mm mags for it. Flawless performance. The Wolf barrels are true \"drop in's\" and it is easy to have a 3 in 1 pistol now, a 9mm, 357 SIG, and 40 S & W for a fraction of the cost of all 3. Wish they would \"do\" a 22 LR conversion too!"

"At first I was skeptical, esp. about any aftermarket items. The fit and appearance were nice, the barrel has some meat to it. So far I have fired 50 rounds (federal) without one single problem. The groupings were darn near hole in hole, shooting at 20 feet. I recommend buying a factory Glock 9mm mag. I will definately shoot my Glock more with this barrel and the recoil was way less."

"I have a Generation I Glock 22. This barrel slipped right in and functioned flawlessly. I put 100 rounds through it after I lubed it, and it did not malfunction once. Of course, I bought Glock 17 mags. Buy this barrel, buy some Glock 17 mags, and you can practice much cheaper than with the stock barrel."

"I bought this barrel for my Police trade-in Glock 22 40s&w and everything worked really well. I put 200 rounds downrange and had one failure to feed, otherwise 100 % I did use a glock 17 mag but the extraction was fine."

"Ordered this on Wednesday, it was delivered Friday afternoon! I also ordered a Glock 17 magazine. Took my Glock 22 with Lone Wolf barrel and 17 mag to range on Saturday. I was amazed. I love the .40 S&W, but the 9mm is less recoil..and 9mm cost less the .40, so I can shoot more. I went through 150 rounds without a hiccup of any type. I feel I now have 2 Glocks. wo guys were practicing for an upcoming match with their race guns, shot my Glock, and were very complimentary. This is a great deal. I checked around before I ordered from CTD and this is the best deal you'll find. And before you say, \"I've found it cheaper\", check the shipping charges on the other one."

"I bought mine over a year ago and I love it. I use 17 and 33 round magazines in my G22. There is an occasional failure to eject, but no major issues."

"Got the conversion barrel for my Glock 22 and I am having a blast with it. So far I have put 500 rounds down range and have not had any problems. 9MM is definitely cheaper than .40 cal ammo.Also, I bought 4 KCI mags and I have not had any problems with them either. I did take them apart and cleaned out the plastic flashing, and put a slight film of oil in them. I loaded them and left them sit for a week, and they now load easily. I honestly have not had any problems.Good products CTD."

"I purchased this barrel to save money at the range. 9mm ammo is half the price of 357 sig ammo and this barrel literally pays for itself. It works great!"

"250 rnds of UMC 9mm 115gr in my Glock 22 with G17 mags. No flaws and very accurate what a good deal, worth every penny. Target practice a lot cheaper and still have the .40 S&W option for home defense,,,2 guns in one."

"Wanted to shoot cheaper 9mm ammo on my G22 for practice. This did the job, I shoot way more 9mm than I do .40 these days. I had a few G17 mags from a G17 I used to own, and now it's like having my old G17 back. Can change from .40 to 9mm in 15 seconds, and it is just as reliable and accurate as my stock .40 barrel."

"This is a terrific product. The accuracy is spot on and it's nice to save some money on practice ammo, plus it gives you a nice little break from the snappier recoil of the .40. Have fired 150 rounds of Speer Lawman 115 gr FMJ without a single hiccup. I do use a factory Glock 17 magazine. The conversion process is fast and easy; the only reason it takes me a minute to do it is because I usually need to let the stock .40 barrel cool off a little. One word of caution: make sure you always wear eye protection when using this product. The extractor on a .40 Glock tends to eject those hot 9 mm casings right back at your face. Highly recommended, and I may get one for my G-27 as well. It really is like getting an extra gun for a hundred bucks."

"I bought this barrel to save some money on practicing. The barrel does fit nicely. But it is not as accurate as an original Glock barrel, no matter the caliber. At 25 yards this barrel puts them about 3 inches to right at about a 5\" group, whereas the original .357 Sig barrel puts them on center into about a 2-3\" group. Another problem is the fact that the recoil spring from the Glock 31/22 is a bit too powerful for the less kinetic energy of the 9mm. So the slide doesn't always make it back through the whole recoil cycle causing stove pipes, misfeeds and sometimes failure to pull the spent shell out of the chamber all together when someone with smaller/weaker hands shoots. So by the time you get the barrel, recoil calibration springs and new recoil rod, you might want to consider just getting a complete G 17 slide. But, just for close range plinking, this option is cheap. You will need a G 17 magazine to go with this."

"I bought this to save some money on ammo without having to go out to buy another gun. Works good sometimes but the casing doesn't eject right and gets stuck. But that could also be the mag which was non-factory."

"Saw a video review of the barrel on Youtube. I have had no issues whatsoever with this barrel. I purchased a few 17 round 9mm Glock mags and now have two guns in one. CTD sent it out fast like always. The spent shells fly back towards you a little vs. off to the side, but that's why we shoot with glasses and a cap!"

"A year, & over 1000 rounds fired since I purchased my Lone Wolf 40-9mm Conversion barrel, I've come to a conclusion regarding it. It's good, but not perfect. I've had malfunctions(mainly FTEs)with it, once every 250-300 rounds. That's not a bad average, but still, not perfect. The conversion barrel is a nice thing to have, when you run out 40S&W ammo, but have plenty of 9mm ammo left, & you want to continue shooting. However, to convert permanently to 9mm. I would not recommend it."

"This is a must have for any Glock 22 owner. I just received mine and tested it yesterday. I had only one failure in 300 rounds and I was using the cheap korean mags and 115 grain 9mm. Accuracy was fantastic. Best accessory for the Glock 22 hands down."

"After I put this in, my Glock jammed several times. I will not blame the barrel though. I read that I could use my Glock 22 mags and load them with 9mm and it will function just fine. Well, it does, kinda. The 9's flew fast and a lot. It only jammed a few times, but I\uFFFDm sure if you had 9mm mags it would work great. If you got 9mm mags then I'd recommend these."

"I have to admit I was a bit hesitant to believe this would work well--but finally talked myself into trying it. What a fantastic product! About 100 rounds fired so far, using Glock 17 factory mags in my G22--Flawless! Accuracy indistinguishable from my factory .40 barrel, with WAY cheaper 9mm ammo. Unless you like spending extra money for practice, and enjoy .40 recoil, you can't do without this. Makes the G22 the best of both worlds--.40 for stopping power in a CCW, and low-cost 9mm range time. As noted by others, you do get an occasional ejection in the head/face (2 out of 100 in my case), but, as noted elsewhere, that's why we wear glasses and caps. And, CTD provided super fast service and shipping. This is almost too good to be true."

"I used this barrel for the first time after I got it. I have a glock 22 gen4. It would not work. Either it did not eject the spent casing or it would misfeed after every shot. I used a new factory g17 mag. I went through two mags and it did not work once. I am not sure why it is working for others and not me. I have the 357sig barrel and it works great. My g22 is stock except for the 40-9 barrel and g17 mag."

"I purchased this barrel to use with my Glock 22, Gen 3. This thing drops right in, uses the same guide-rail and spring. Just order a 9mm magazine which will fit in your Glock model 22 and you are all set!This barrel has been very reliable with no issues. I recommend this to anyone who is thinking about shooting cheaper with your .40."

"So I was worried about this barrel in the start. I have heard of people filing down the feed ramps to make them work and some just not working all together. Well, I'm here to tell you that you do not need to do any of that. You really only need a 9mm mag and the barrel. The Gen 4 double spring does not need to be replaced, even for a 115 grain round. I bought a 31 round 9mm off brand Glock mag and shot all 31 rounds as fast as I could pull the trigger, and had zero problems."

"I bought this when a friend told me about it. I bought it because I have a .40 S&W Glock 22 Gen3 and wanted a 9mm Glock 17. Let me just say that after buying this product, I saved myself about $350. After taking it to the range, I can safely say I'm fully satisfied with my purchase. I first fired a lot of .40 S&W rounds, and then put the barrel in. Wow, what a difference in recoil!!! As far as accuracy, I was getting hits in the 10 ring with no problem. Only one failure to fully eject in about 200 rounds fired. This may be due to the cheap ammo I was using or maybe limp-wristing, as I started to get sloppy a bit after several hundred rounds. Well worth the purchase."
