    Awesome vid I really appreciate it because now I know I gotta go get a 357 barrel to shoot the 357 cig because I got home with it read the mag and was like oh shit and not knowing was fixing to shoot the 357 without changeing the barrel but after watching this now I know so thanks

    Neck a .40 S&W casing and it would be too short. The starting case for .357sig is 10mm. Also the .357 sig bullets are slightly tougher than your common 9mm bullets. Otherwise all other comments are valid.

    Can I put 40 shells in a Glock 31 ?



  4. JAF Supply on August 31, 2022 at 8:18 pm

    Would you know if the M&P barrels are compatible with the sd40ve?

    I own SIG P226 in .357 SIG. loaded with Underwood .357sig 115gr. it’s a hot load,,, ( THAT’S WHAT SHE SAID. ) seriously its screaming demon hard hitting mofo. 1450pfs too 1580fps I EDC .357SIG AND RANGE TIME .40CAL (9mm isn’t even in the same ballpark )



  12. Kenny Strange on August 31, 2022 at 8:27 pm

    Great!! I have the m/p 40 was wondering if you could really do that..



  13. Michael Rodriguez on August 31, 2022 at 8:28 pm

    So you HAVE to convert the .40 slide to fire .357 sig and .40?



  14. Most Perfect on August 31, 2022 at 8:30 pm

    My m&p 40 c always jam after the first shot..is there a reason why? Help me



  15. mksthill on August 31, 2022 at 8:30 pm

    Has anyone else here besides me converted a 40 S&W Shield to 357 sig? It makes for a nice package in my book, but I’d be interested in learning what others think. It’s certainly more fun to shoot than as a .40.



  16. Christian Layman on August 31, 2022 at 8:32 pm

    I wanted to buy the conversion barrel but I can’t find the barrel for my M&P .40 2.0.



  17. BamaBoi1991 on August 31, 2022 at 8:33 pm

    Great video I just purchased my m&p 40 and was noticing the mags say 40s&w /357 and this video explains it all thanks



  18. MEGALODONS CORTEX on August 31, 2022 at 8:35 pm

    Where to get that and the 9mm barrel



  19. Torris Hicks on August 31, 2022 at 8:36 pm

  20. Jerseydre856 on August 31, 2022 at 8:36 pm

    What size barrel 357 do I get I got the 40 smith &wesson m@p40 m2.0



  21. Orion Steve on August 31, 2022 at 8:37 pm

    Informative video but dude you shoot like absolute dog shit. Quit snatching that trigger and maybe you’ll shoot better



  22. traxxastrucks36 on August 31, 2022 at 8:38 pm

    Just ordered a Smith and Wesson M&P 40 compact M2.0. Have a KKM 357 Sig barrel coming for it. Thanks for the video. šŸ‘šŸ»



  23. Andy & Amys Arizona Adventures on August 31, 2022 at 8:41 pm

    Well said,just picked the same gun,can’t wait to fire it.The 357sig is awesome at long rang over other semi auto calibers. The sig also has thicker brass and barrel .I have become really fond of the the quick snap of the recoil, good videošŸ‘



  24. William Lennox on August 31, 2022 at 8:43 pm

    I need to try this conversion. I’ll see where I can buy this barrel the cheapest.



  25. Emillionaire 2k18 on August 31, 2022 at 8:44 pm

    HELL Yeah! Dope Video! Very Informing!



  26. Randall Hatcher on August 31, 2022 at 8:45 pm

    I have a 40 S&W . I’m thinking of getting a 357 barrel for the extra velocity . But what about 40 calliber plus p plus hollow points ? Would they be equal in velocity ?



  27. Richard Swan on August 31, 2022 at 8:47 pm

    Does the 357 barrel have to be m&p



  28. bradh74 on August 31, 2022 at 8:47 pm

    Not sure if I missed it or you didn’t say. Where did you get the 357 sig barrel?



  29. Jesse Perkins on August 31, 2022 at 8:48 pm

    I can tell how much it sucks doing this in the coldšŸ˜…



  30. door gunner on August 31, 2022 at 8:49 pm

    Just bought a m&p 40 leo trade in.Glad to see this video.I have some NO WAY friends and this will prove them wrong.Ordering my 357 barrel now.



  31. Troy Hutton on August 31, 2022 at 8:49 pm

    A lot more energy,Better round flatter shooting and very accurate. Out of the box many popular brands Iā€™ve had similar results to 10mm with 357 sig . A lot of ammo loadings are weak on 10mm . Only High end specialty 10 mm separates itself from 357sig or hand loading 10mm . Those 2 options provide awesome options. 357sig seems more consistent in more ammo offerings .



  32. Carlos Yehuda Lopez on August 31, 2022 at 8:52 pm

    Great video Thanx for posting…



  33. Poke12Gauge on August 31, 2022 at 8:53 pm

  34. Antonio Baskerville on August 31, 2022 at 8:55 pm

    Thank you For the Demo Video !



  35. Victor Williams on August 31, 2022 at 8:55 pm

    Good information I just picked up the S&W M&P 40 2.0 compact and didnā€™t know you can swap the Barrows, where can i pick up the extra barrow.



  36. Lt_Dans_Legs on August 31, 2022 at 8:56 pm

    Im sorry but you can’t shoot watching you pull that trigger cracked me up šŸ˜‚ just squeeze it you were tryna break its damn neck šŸ˜‚



  37. Lathaddeus Anthony on August 31, 2022 at 8:57 pm

    To shoot 357 bullets in 40cal m&p do I have to change the barrel



  38. Colt10mm Security on August 31, 2022 at 8:58 pm

    Older video but still good. I recently put a KKM .40 barrel into my Glock 32 (.357Sig). I tried to load up the Speer 40cal 180gr TMJ into the Glock 357Sig magazine and guess what? It does NOT work! The problem for me was the .40 bullet doesnā€™t fit between the ā€œnoseā€ end (bottle necked end), of the magazine through the feed lips. I was so ticked! It looks like Glock slightly tapered the nose end or ā€œshoulder endā€ of the feed lips, thus preventing a wider (No shoulder) bullet of the 40 from functioning properly in the magazine. So, I just ordered some Glock 23 (40 cal) magazines and theyā€™ll get here in a few days. Iā€™m hopping that it will work because .357Sig ammo is near $50/box per 50. If the new mags work, Iā€™ll buy more Glock mags in .40 in that case. Hickok45 mentioned the same issue on his channel. He briefly explained in one of his Glock 357/40 videos of using one of the two magazines for a caliber swap, but he couldnā€™t remember which mag would feed both calibers. It looks like I figured out what he meant now. It seems that the feed lips are slightly narrower near the shoulder only and on Glock 357 magazines, than their 40ā€™s. I know people that do the 357 conversation from a .40 Glock gun, but not the other way around. Itā€™s nice that S&W just uses the same interchangeable magazine between the two calibers.



  39. Jesse Rodriguez on August 31, 2022 at 8:58 pm

    No the 357sig started with Sig P229 than P226 than the Glock 31,32,33,



  40. traxxastrucks36 on August 31, 2022 at 9:01 pm

    I reload 357 Sig and push them mid 1400fps using a 125gr Speer gold dot bullet. Hard hitter for sure.



  41. Ward Atkins on August 31, 2022 at 9:01 pm

    Those calibers are all deadly " it’s a matter of perspective " reality guns kill in general



  42. Luis Lopez on August 31, 2022 at 9:01 pm

    To bad that 357 Sig barrel & Ammo is impossible to find in 2020



  43. Ryan Bond on August 31, 2022 at 9:03 pm

    Can I swap the barrel in my sd40 to do the same?



  44. John Mcknatt on August 31, 2022 at 9:03 pm

    will this work with my s&w40ve ?



  45. Brian Johnson on August 31, 2022 at 9:05 pm

    Where did you find the conversion kit ??so all it is , is a barrel swap ?? Nice



  46. DIXIE MAN on August 31, 2022 at 9:05 pm

    Hi: Can I convert my 9mm M+P SHIELD to a 357 Sig in this same manner? Can I convert my 40 M+P SHIELD this way? Where can I get a 357 Sig barrel? Thank you. GREAT VIDEO.
