Is it feasible to convert a P6 to 40 S&W? Besides a complete Slide & Magazine, anything else needed? |
| I think this would be a huge no-no. In the first place I don't have any idea that other slides and barrels would work on the 225 / P6 frame, and second I suspect the expense if they did, would be far more than the cost of a 239 or 229. For sure, there would be no support from Sig for this either. Besides, with the right loads, I think the 9mm gives up very little to the .40...but that's just me. |
| One of the reasons SIG came out with the 229 and its milled stainless slide is they didn't think the stamped slide of the 228 would hold up to 40's. Since the P6 slide is basically the same as the 228, it would seem the answer would have to be no. I'm sure its at least theoretically possible to do it, but not cost effective and probably just a plain bad idea. |
You must have been asleep most of your life! Yes, I can buy an complete slide/barrel and maybe magazine and make my 1911 a: 45 ACP or a 45 Super or a 10mm or a 40 S&W or a 9mm or a 38 Super or a .22 LR or even a 38 Special WC… Gosh, I don't have buy 8 separate guns to get it done either… |
Changing calibers on 1911s is not as easy as you make it out to be. At least not if you want something that will run 100% in all calibers. You will want a ramped barrel for 9x19 and others, while typical .45 ACP barrels are not ramped. This is not just a barrel issue, since the type of barrel determines the type of frame allowances. So you're stuck with going one way or another. Different ejectors (frame part) are typically needed as well. Not to mention the great deal of fitting and hand-tuning that will be required to get additonal slides to function 100% ona single frame. 1911s are not drop-in-and-go guns by any stretch. |
Nonesense! Yes fitting is required, but I have never had to go to a gunsmith to get it done! I am not going to enter a which one is better. I asked a simple question, and you good folks have replied that SIG's design does not allow the versatility that the Colt system has. And that versatility has a price so you go with the one you like... |

you said colts not 1911's. Either way it is not very practical. But if you thought ahead and wanted a sig that could change calibers you would know that you need to start with a larger caliber and convert down, not buy a 9mm and expect it to be engineered to handle a higher pressure cartridge. You could have easily bought a .229 and converted to 9mm or .357 sig if thats your thing. I would rather invest in complete guns instead of a pile of parts with 1 frame. YMMV. By the way, this is a sig forum, did you expect a "you're right" reaction to the colt remark? |
 how so? The gun I mean. I'm a 1911 man, but not die hard, so I'm curious why you're not impressed with it.I've not held mine yet seeing as it's back home in PA at my parents place. |
First lets start off by saying that the 1911 is a great platform but it really hasnt changed since its inception. This allows for lots of companies to come along with some designs that allow the 1911 to be converted. They will continue to develop these things because the gun will remain the 1911, a very popular platform . Sig and other manufacturers have different makes, models, and sizes so it is not practical to have all of the conversions that a 1911 will. Sure, some parts are interchangeable with different sig models but you arent going to see a big market for conversion products. I hope that clarifies |
