I found a good deal on a Certified Pre-Owned .40 cal at a gun show and purchased the gun. After I got it home, I decided to go ahead and buy a .357 barrel and a .22lr conversion so I would have multiple options when I went to the range.
So, now the difficulty starts. I received my .357 barrel and tried to install it on the weapon. No luck. The original barrel works fine. Easy in, easy out. It seems like the new .357 barrel is sliding back and then the feed ramp hits the locking insert inside the frame. Thinking there might have been some problem with the new barrel, I make arrangements to exchange it for replacement and back to the vendor it goes. Next, the 22lr conversion comes in and it installs and shoots like a dream. While I'm waiting on the replacement barrel, I find a used .357 barrel on the Equipment Exchange and figure "Why not?" I know its been in another gun and worked properly. The new barrel and the EE barrel arrive on the same day and I immediately install the EE barrel in my gun without problem. I remove it and try the new barrel. Same problem as before. When I move the slide to the rear, It stops where the feed ramp is hitting the locking insert. Now for a few questions. 1. Is the anodizing on a new barrel thick enough to cause this problem? 2. Can I sand down the top of the block on the new barrel (or feedramp) if necessary to allow the barrel to clear the interference? I know it might change the POI/Aimpoint. 3. Anyone else had this problem? How did you resolve the issue? Any other suggestions (other than the obvious gunsmith)? Thanks Since I received so many different suggestions and had no practical experience, I decided to do the safe thing and take it to a gunsmith. He removed a little material from the bottom of the feed ramp to allow it to slide properly into the frame. Total cost $25.00 |

Is it an aftermarket barrel? (Like Bar-Sto.) If it is, it may have much tighter tolerances and require fitting to your pistol. Some require extra fitting, some just drop in. I used an emeryboard and smoothed it down ever so slightly. Bar-Sto, EFK and other after market barrel makers have instructions. |

That does sound odd. If it's a Sig OEM barrel I would think it should fit without any modifications being necessary unless some modifications were made to the handgun itself. (But the 2nd .357 barrel fitting and working without issue would seem to rule that out) Again, if it were a 3rd party manufacturer some fitting could be expected, but as a Sig OEM part... Try calling Sig Customer Service @ (603) 772-2302 (press #3 for Customer Service) during normal business hours. Describe the situation & the OEM/packaging of the part to see if they can shed any new light on the problem before attempting to file anything down or engaging a gunsmith. |
| I got a SIG barrel in .357 SIG for my .40 S&W model 229. The barrel hood was just a tad long and required a bit of hand stoning to allow the barrel to lock up in the slide properly. The good news is after I fitted the barrel it worked fine and is super accurate. Don't be too surprised that your barrel requires a bit of hand fitting. |
| I bought both my 229 in 40 and a 357 barrel brand new. I also had the same problem with the fit because the coating is a bit heavier on the new barrel. It is a common problem I am told with these new stand alone barrels. I took it back to Top Gun Supply, where I bought it, and they slightly sanded to the parts that were catching. When checking the barrel you can se they barely took any off and it fits like a glove now. |
