The problem with the .45 model is the ejector is in a different place and even if you could find a barrel and slide to git the 1911, the ejector would hot allow the slide to be mounted.
The barrels on different models are not the same. They are of different lengths and even different configurations on some of the short models. Full length 5” barrels are extremely common. I have no idea about the officers model but am sure it would be less common than the regular barrel.
Thanks again, I certainly appreciate it. I will make sure to look quite closely at the conversion kits I was previously interested in to see if I missed that. Honestly, though, for target practice since 9mil ammo is cheaper than .45, even a single-shot, manual eject and slide-release would work. Just need to keep the shooting skills / accuracy up is why I was considering the conversion. I would just change it back to .45 after the target practice when I was finished.
Hmmm. About the barrel(s)... the Officer’s Model I acquired is all stainless steel, but I was under the impression that was the only major difference between it and similarly-framed and -sized versions. Too, I think the barrel is 4 1/2” if I recall correctly, so I need to look further into that it seems. Another good tip. Thanks.
