I am considering a 40 cal to 9 mm conversion barell on my Glock 27.
I have seen the Lone Wolf brand, does anyone have advise, or experience with this....or any other barells?

Safety, reliability, etc

Thanks
Vic

I'm waiting on my CCW permit app to finish processing before picking up my G22. In advance I have in my possession 2 "Storm Lake" barrels. one in 9mm the other 357 sig. Looking forward to testing them out soon! I ordered them from glockworld.com, quality looks good.

I'm looking at the same thing. One in 9mm, then one in 357 sig. I have the G27 and was thinking of getting the barell for a G23, non threaded. I know it will be almost a half inch longer, but I am just wanting it to look different anyway. I have heard that a G22 won't fit due to different lugs, which doesn't make sence to me, oh well. That is my plan, unless anyone can give me a reason not to. The extra barells would be for range duty only, not CC.

What is the benefit of the .357sig instead of the .40? Is there any? I know both rounds will get the job done...just curious pros/cons of the two compared. The .357sig is no .357mag from what I've read thus far. Really haven't seen anything that shows the .357sig to be superior to the more common rounds... Anyone know?

For my purposes, it just gives me different options on ammo at the range. As far as SD, I couldn't tell you of the benefits. It's like having a different gun to take to the range for me, just something different. I will shoot .45 for a while, change over to .40, then would like to shoot 9mm, and 357.

I have been shooting a Lone Wolf 40-9 conversion barrel for over a year now. It has been 100% reliable and very accurate. I also bought a 357sig. barrel from Storm Lake. It is as well made as the Lone Wolf. I like the 357 rounds because they offer a 9mm-ish bullet propelled by 40s&w power. It offers greater bullet speed and therefore higher penetration. It is another option as was stated above.

CCW Permit came through, went shopping and picked up my G22, G36 and SA 1911-A1 Range Officer (Life is good). I plan to test out the 357 Sig and 9MM drop in barrels this weekend for the G22, will let you know the results.

The nice thing about geting a .40 caliber Glock in the first place is the ability to drop in a .357SIG barrel, .40S&W barrel, and then a .40-9mm conversion barrel.

All you need to convert to 9mm is the conversion barrel from us and the Glock OEM magazines that go to the 9mm equivalent model of Glock you are using.

Maybe for a conversion the LWD will be fine. But I am very disappointed with the lack of consistency and accuracy I get from my LWD G34 slide/barrel. The performance is similar to a military 1911. My OEM (almost) G17 is twice as accurate as the LWD set up. Also, the LWD slide appears to be very soft. The peening is much more apparent in the G34 S/S slide than my OEM G17 slide (there is NO peening). I won't be buying LWD barrels or slides in the future. My G34 is now my tucked away-in-my-vehicle-last-ditch survival gun.

I have two G22's and one G23 that have a LW 9mm conversion barrel for each. Not one problem. I also have a 10mm=>40s&w that has not had one problem. Good products. A good number of my friends have them as well and have had no issues. We have put hundreds of round through them.

If you get one, before you shoot it, clean it with some real strong cleaner then soak it in clp and wipe clean. It helps with clean up and break in.

I know this thread has some age on it, but I just ordered the LWD 40-9 barrel/ 3 glock 17 mags today for my G31 .357. And will be picking up a .40S&W barrel in the near future for versitility.
I like the .357Sig round its self and was introduced to it via a Sig P229 DAK. The recoil impulse is different from .40, it has less muzzle flip... and
Design wise its an accurate cartridge.
It tends to best 9mm+P+
the downside is a box of winchester USA fmj tends to be $27-$32 dollars
For 50. The ability to practice with 9mm allows 3 shots, to 1 for the same approx cost. And I allready have 9mm handguns so nothing new to buy ammo wise.

I am a bit late to the party on this thread but I'll post anyway.
I have converted my G23 to 9mm with a LW 40-9 barrel and I am very pleased with the result. It shoots very straight with no malfunctions after about 300 rounds. The heavier barrel has reduced muzzle flip to virtually zero. In the negative column, I have one caveat however. Some on this forum have said that it is not necessary to change the extractor to the 9mm version. This is true-ish BUT, if you examine the spent casing, you will see a good size dent in the brass that you have not seen before. This dent is caused by the larger 40SW extractor trying to wedge into a smaller space. While I had no malfunctions after 300 rounds, I reason that the extractor wear is accelerated and there could also be a weakened point on the brass. If you reload your brass, this could be a problem. Glock parts are not expensive so when I convert to 9mm, I also change the extractor and the plastic bearing on the end of the spring.
Just my $0.02.
