If it is marked .40 S&W then that is the caliber....JJ
Hello i am new here, have a question. back in the 90's I bought something For one of my sigs that i thought i had to have appearently didnt need it as bad as i thought because i was cleaning out my safe and found this barrel new still in package. I remember I bought it to convert my 229 to a 357sig. I was looking on the package and it says .40s&w barrel for sig 229. so my question is did they give me the wrong thing or does this work for the 357 sig? Thanks for your help.
If it is marked .40 S&W then that is the caliber....JJ
It would require a .357 Sig barrel.......JJ
I have seen and shot a .357sig out of the .40sw barrel in a 229 and it was fine. (not my gun!) Since the bullets are so close everything functions proper. But they are CLOSE not perfect matches. It's extremely likely you can blow a hole in your hand if not worse by tryin this. You could get lucky (as I have) but it's far more likely you'll get hurt. Go to topgunsupply.com you can buy the .357 barrel and not hurt yourself!
Also buying the upper reciever and barrel to make it a .22 is awesome! So much $ saved on ammo and you can still get the thrill of shooting your favorite gun!
I have two examples. I got a .357 SIG conversion slide and barrel for a 9mm 226, then got a .40 S&W barrel. The .40 barrel fit fine with no problems. I got a .357 SIG barrel for a .40 229 and the “drop in” barrel didn’t drop in. I had to carefully grind just a bit off the hood for it to fit. I fitted it and it shoots great, but it may or may not “drop in” for you.
