Always good to see practical advice for making the most of our firearms

Swapping barrels for different calibers like .45 to 10mm can really change up your shooting experience.

Was wondering why it was stovepiping every few rounds w the 10mm barrel. You just saved my life from a Grizzly Bear Lol. Thanks Lenny!

I just said f it and bought a 10mm slide 🤷🏻

Dang it, Lenny. Looks like i have an excuse to go pick up a .45 now and get the 10mm conversion barrel. Lol

I’ve seen these around before from some other companies, but if you guys are making them too, I’m sold!

This was an awesome video and to the point

I have bought your Double Diamond .40cal/9mm conversion barrels and love them. I was excited about .45/10mm but when I got mine it failed to feed. Extraction was fine. Seemed like the long 10mm just would not make the turn at the top of the ramp (maybe it doesn’t actually make a turn, but that’s how it looks when the round is stuck there). I sent it back, got another one and had same problem. Gave up and got refund. I had correct mags and oiled the new barrels. Tried two kinds of ammo. It was in my Gen 3 G21.

What happens if you put in the 10MM extractor, with its additional .025" engagement length in the slide, and fire .45 with the original barrel?

Good information sir

Mr Lenny Maggill Always Staying Yolker Up… A Pleasure Good Sir To See you Doing well Sir.

A++ video Lenny!!!

solid info as always!🇺🇸

Love me some Lenny but, just buy a complete slide on this conversion. Although this will work its worth noting the 45ACP slide breach face is larger than a .40/10mm slide breach face. Also the ejector is different angle.

Hey Lenny love ur content. I purchase my glock survival kits through u. Would u recommend doing all this with the 41 Gen 4 knowing the slide is thinner? I wanna convert the 41 to 10mm thinking it would shoot more accurate maybe lil less recoil being the larger frame and longer slide than the 21.

Lenny, please make a threaded conversion barrel for the G30!

I've read hard cast lead unjacketed are supposed to be fired in Glock barrels. True? And is the Diamond 10mm conversion for my G30 like that also?

I'll have to try an extractor; I've had a 10mm conversion barrel for my G21 for years, but hardly shoot it because it mangles and tears up the brass beyond resizing in a reloading press.

Lenny.... why would I got to the trouble of replacing parts in my G-21 to convert it to shoot 10mm.... when I could just buy a G-20 and have TWO powerful Glocks? Come on Peeps.... open the checkbook!!! 🙂

so maybe a year ago, they had the conversion .40 to 9mm also for the Gen 4, to make my .40 M27 to run like a 9mm M26. Well it did not work out and later found the Glock Store had to update the specs because the 9mm did not work on the G4., I have the 19, but wanted my M27 to run like a M26 9mm. I also have g4 for M29 and M30, so not sure if this would make any advantage to me. I love my 10mm.

Do you have the longer 10mm barrel for the alongside MOS?

Please make a video on your black nitride re-finish. I’d like to learn more.

I have the 10mm to.40 conversion barrel. Don’t need to swap magazines. I put the 40 barrel in for training only.

Okay Lenny, question, totally off the subject of .40 to 10. I have a 80%, every time i rack the firing pin nob gets stuck on the back side of Crucifix and the slide wont come off. Ive replace every from the trigger and bar to everything in back. What's wrong. I know you'll probably said the 80%... lol

Does anyone know what Glock frames will accept a Glock barrel # 2240 TH? Happy 4th of July

Can you do a video on 10 mm to 50 cal.

Lenny I thought you where converting a 45 acp to a 10mm 18:48 and a a few more times you said 40 cal from a 45. In the beginning I was with you but you lost me when you started talking about 40 cal I had to rewind the video to make sure I didn't miss anything I think you might have gotten off track I know it's easy to do when you deal with as many different firearms as you do. Great video I think this video will fix a lot of people's problems with the 10mm conversation kit witch could be everything from stove piping to failure to extract. When I ordered my conversion kit I ordered a new extractor for a 10mm because I knew the case heads where different sizes.

When you're use a conversion barrel 40SW to 9mm, do you have to change the ejector I suppose? I don't even live in the US and I like a lot this videos XD

What..... Lenny talking about Glocks... woe someone pinch me am I dreaming??

Lenny... is your channel non-monitized.... or how are y'all getting around KZfaq's rules about showing modifications on firearms? Just curious. Tks!!

When I purchased my Double Diamond10mm conversion barrel from you several months ago, your website said there was nothing else to buy. Simply swap out barrels and go. Now all of a sudden, a different extractor is needed. What gives?

Should I change the extractor back to the 45 when converting back to 45acp?

Makes more sense to just have 2 complete slide assemblies and swap back and forth.

What about the Glock 36?

Do you have these for the G21 gen 5 ? And do you have to change the extractor also ?

@glockstore Lenny do you recommend the hot loaded 10mm underwood ammo? Ive read store bought ammo is loaded the same as .40 S&W

Hey how can I find out info on a Glock 19 that I have owned for over 24 years?

Some guys say they would trust conversion kit in grizz country and to just get real 10mm. Also, does this technically make this bull barrel and better accuracy. And what model is the long barrel 10mm I forget.

Хорошо):

The sound effects.

Do you have a 10mm to 40 caliber conversion?

Will this work on Glock 36?

make a conversion barrel for the 30s! because theres is none!

So why doesn’t the 10mm convert to a model 22?

Folks, although this can be done, don’t mess with Glocks keep them in stock and just buy a 40 and a 10 mm if you choose to have both calibers don’t be swapping the barrel then swapping the extractor you’re gonna have spring issues recoil issues slide mass issues just get two different guns

Why not just buy a 10mm slide instead of having to swap out extractors?

Actually a .40 is a 10mm cut in half

Boom!

Is Lenny having a "Biden " moment? The Video is confusing saying .40 cal to .45 on a video about a .45 to 10mm conversion (Unless I miss understood) Other than that the video is awesome and I didn't know I could do this.... Question? Can I make my Glock 30S (.45acp) into a Glock 29 (10mm) using your conversion barrel ?
