    Colt 1903 conversion?

    So i have a colt 1903 .32 and was curious if it was possible to convert it to a .380? I have read and done some research some say it can be done some say probably not. My idea or plan is to possibly put an entire .380 slide assembly and place it on the .32 frame and use a .380 magazine. Ive heard the 380 slide would fit on the 32 frame and id be using a 380 barrel and extractor that came with the 380 slide. I heard the 380 will be snug but itll fit inside the 32 frame. Curious if this is probable.

    Anything is possible. But the question is begged.

    Why?

    Been a while since I massaged these brain cells, so forgive me if my memory isn't 100%.

    There are several versions of the 1903. Many of the .32's will not accept a .380 magazine. So your first step is determining which version of 1903 you have.
    Or it's as simple as this... If the .380 magazine fits, then its really no problem at all. If the magazine doesn't fit in the mag well, then its not really doable.

    I read some years back about using a 32 brrel as a conversion for the Pocket Hammerless, you don't even need two slides as the breech face is open on these Colt's.
    But as posted with the .32 and 380 we have the 380 magazine will not go into the 32.

    Someone asked why. Id rather have a 380 than a 32 since its a larger bullet and i like to carry the 1903 around sometimes so id like the bigger bullet if i can. I have a 1903 built in 1919 so i have a type 3. I suppose i can always just buy a 380 magazine and see how it fits inside the mag well. If it fits ill perhaps try getting the entire slide assembly and give it a shot.

    Buy a Colt 1908 Pocket Hammerless in .380acp. Colt built them right at the factory, and distributors sold them to the public. Now they are on the secondary market, and anyone who can pass a NICS test can own one.

    I dont want to spend that much. Ive already scoured the web for one and a nice one theyre running a little under a thousand. Itd be cheaper for me to build one or do a conversion if possible.

    I had a M1903 in .32 ACP a long time ago. I misplaced the magazine for it. The LGS a friend owns had a .380 magazine in their spares. I used that for about a year until I found my original .32 magazine.

    Spend a thousand, and you will have a gun worth a thousand dollars.

    Spend $400 on a shooter grade in .32 acp, and spend $2-300 to convert it to a pseudo .380 acp. You will have a gun which may or may not work, and is worth five or six hundred dollars less than you have in it.

    Do you specifically want a bigger bullet, or just better results with ammunition? You may want to save yourself some money and just research ammo. There is some ammo that outperforms others. However, a .380 will always start out bigger than a .32.

    If you are looking to convert your .32, why not just sell or trade it for a .380? Or, if you truly must have a pistol you can convert to shoot other calibers, you might want to consider the old HK4.
