Glock 40 replacement barrel in .40

Its only been in the last few years I’ve been able to buy the guns I’ve always wanted. The catalyst was after finally sucking it up and getting my degree, I started making okay money. I have an advantage in that I don’t have any debt..no mortgage, no car payments, no nothin’. As a result, whatever I do make, I wind up keeping a large chunk of. This means that what might be considered ‘just enough to get by’ for some folks is ‘plenty’ for me….although more is always better.

One of the things I’d been wanting for a while was a Glock 10mm as a belt gun for when I was out in the boonies. And, I got one. I threw some quality night sights on it, bought a half dozen mags, a lovely flap holster, and thats pretty much all I really need to do. Except…10mm ain’t cheap. Nor plentiful. But what is cheap(er) and plentiful is .40 S&W. Turns out the folks at Lone Wolf Distributors make a .40 S&W barrel for the Glock 40. I suppose I might have to change the recoil spring out but given how factory 10mm is watered down to almost .40 levels, I’ll bet all I need is the barrel change.

This’ll be a somewhat more affordable way to practice since I have gobs of .40 S&W ammo laying around from the local PD. And, I suppose, from a preparedness standpoint it’s a good idea to have a couple Glocks laying around in .40 since there still seems to be a ton of badges out there still using the .40 S&W.

Personally, I plan on picking up some 200 gr. bullets and loading them up more to what the 10mm was designed for. If modern 10mm loads are loaded down to hot .40 S&W levels, why wouldn’t I just get a .40 S&W instead? Nope…this’ll be a bit of a project for the reloading bench. If I have to ruin a bruin then I want as much metal going downrange as possible.

It’s nice that I finally have the career path that lets me afford stuff like this. I just wish I had more time available to take advantage of the new toys. But, I guess thats the trade off…time vs money.

  1. As your ((invisible internet) friend I’m so glad that you got a degree which led to a stable at least reasonably well paying job. You’ll be able to earn a solid living for as long as needed/ wanted.

    That time vs money thing is real. I greatly reduced my shooting and quit shooting sports a few years ago largely because I didn’t have the disposable income any more. Now things are going better money wise but I’m busier than a one legged man in an ass kicking contest.

    • You know, when we were younger we had plenty of time and no money, when we’re older we have plenty of money and no time. You’d think there would have been a point on the graph where those two lines crossed and life was perfect.

      • Life became perfect for me when I retired from a wonderful aerospace career at age 55. Now I have six Saturdays and one Sunday every week and more fiat than I can spend.

  2. The only thing about reloading the glock in 40 cal is the cases tend to bulge where the barrel doesn’t support them. I seen cases rupture .

  3. It sounds like a good place to be. A ;pistol taking two different performance categories makes a lot of sense.

    Back in the 90’s, I was going to buy a kit for my Series 88 TZ-75 9mm to become a .41 Action Express. But I could never find one that met my budget so never got there. It is just as well – .41 Action Express brass and components are probably in the nearly extinct category.

  4. Congrats on the income stream. I have been having an ongoing Bruin problem.
    I heartily endorse the 10 with 190 grain copper solids at 1250 fps. nothing better.
    I had a face to fur encounter at 60 feet. 400 pound plus beautiful healthy boar.
    I chose to grab the long gun 30 – 06 Rem. 700 bolt. IT WAS NOT ENOUGH GUN.
    Two shots was all it would produce at that distance in the time available. I was backed up by an adult son with a pistol also not enough gun. 45 1911 single stack. Second son had a magnum 13.4 oz can of bear spray UDAP brand he engaged. While walking forward while holding his breath ballsy move on his part. The Boar turned swapped ends in an instant took off and changed zip codes at warp speed. I
    I still pack the 10 mm loaded hot. I also carry a can of UDAP as do both of the boys.

  5. you might want to swap out the extractors also…they are a tad different rounds in size…and the angle of the extractor is different…

      • Yeah, but I’ve also read that it puts unnecessary stresses on your extractor since thats what the cartridge is headspacing on. The article you linked addresses this by saying “I’ve done it and never had a problem” which may be true, but I need a bit more than that. I can afford a replacement barrel, and I like the notion that I’ll be able to shoot even cheaper cast bullets out of the Lone Wolf barrel, so, for me, I feel the extra barrel is a good idea. However, its nice to know that in a zombie apocalypse I can run .40’s through the gun as-is. Although, to be honest, the I’d run out the door with a gun in a caliber other than 10mm in a crisis if I had a choice.

  6. Notes on Alaska carry:
    .44 Remington mag/ minimum 6″ barrel is the absolute MINIMUM
    more preferred is the .500 S&W
    better is .454 Casull
    Best is .460 S&W
    but the .460 S&W is like carrying a carbine rifle

    at least the Casull in a Ruger or Freedom Arms package is like carrying a handgun

    Automatics are not the tools for bears. How much is your life worth?

  7. I’ve got a Ruger 10mm Match Champion that uses moon clips. Using thicker moon clips it also takes .40 S&W. There is a difference in the rims that requires this. It’s only 6 rounds, but allows longer, heavier bullets. Gray Fox

  8. “I started making okay money. I have an advantage in that I don’t have any debt..no mortgage, no car payments, no nothin’.” – I added one other advantage – no wife – without someone I had to answer to for every firearm purchase, or even worse, beg for pre-approval on firearm purchases, I bought whatever I wanted to buy with my money, and never had to listen to “You wanna buy ANOTHER gun?”

  9. Greg here pistols can put bumps on a bear faster than he can rub them. If you can it will. Most revolvers hold 6 rds. the 454 casual just 5 rds. My Glock s in 10 mm hold 16 rds. I can shoot split times at .15 to .17 hundredths of a second. On a standard b23 sil At 15 yards. That is 16 rds on target in less than 3 seconds. Penetration in ballistic gelatin is over 36 inches. There are revolvers that have more potent rds. None hold 16 rds loaded to 41 magnum balistics NOT A ONE. Reliable my first 10 mm Glock went 5000 plus rounds without a failure to feed or fire or eject. All rounds were 200 grain hard cast handloads at 1250 fps. The pistol was cleaned every 1000 rounds. It is not how big your gun is but how fast you can put your hits on target that decides the outcome. Get a 22 lr conversion unit (advantage arms) my choice to develop speed. I now have an M1 Garand with 8 rounds 30 – 06 150 grain solid copper Barnes bullets. Dump time 8 rounds in under 2 seconds standard bill drill take care all.

  10. Have been closer to a bear than I ever thought or wanted to be(tent wall-we could hear each other breathe). If a more serious interaction occurs damage placement is key as any animal has natural strengths and weaknesses; bone structure can be incredibly resilient so look for vulnerability ie,snout,eyes,ears, palate or other path to sever central nervous function or drop blood pressure immediately or cause enough discomfort for a change of attitude . Bear spray backed up with 12 gauge and ability to hit eye size target at range under extreme stress. Calibre helps but placement is key.
