MY MOUSE GUN SHOOTS 22 SHORT AND 25 ACP: Astra Cub 22 to Colt Junior 25 conversion

Love my Spanish Astra Cub ( Colt Junior clone) in 22 short. Did a lot of naughty staff with it- see other videos.
It,s one of the smallest and simplest semi auto pistols. Easy to work with. Great Browning design.
It also comes in 25 ACP, so does Colt Junior.
I wondered and asked around if they share parts and can convert into each other.
Scattered info, vague. Story goes: there was 22 slide+ barrel + mag = kit for a 25 pistol.
The mag well had to have a groove for the 22 mag loading button.
I could not find anybody who converted 22 to 25.
I like a challenge.
I made it more difficult as I bought American made Colt Junior aforementioned parts.
I knew that Astra was contracted by Colt, but the issues of dimensions, tolerances might be a thing.
I took my chance, and here,s my journey of the conversion- the fitment and adjustments took me a few hours.
Some problems and solutions of fitment, assembly and finally performance/ feeding issues. All solved.
I am satisfied: as I have 2 different caliber guns on one frame. Both work very well.
Enjoy.

I did basically the same thing with my Beretta 950b "Minx" in .22 short. Converted to .25 with a new barrel, mag, and slide (with all internals, such as firing pin). I also threaded my shorter .22short barrel for suppressors.

[@STEINBVG]

Did you have to do any machining or it was simply plug and play?

[@1lovesoni]

@@STEINBVG Plug and play in my case. I just had to press out the barrel pin. It helps that Beretta manufactured the 950b in both .22 short and .25acp. Though, the barrel threading DID require machining and attaching a barrel extension.

[@STEINBVG]

Thanks. So the barrel is fixed by a pin? DO you have to punch it out every time you wish to change calibers? Or you just stay with 25? Because with the Browing barrel locking design, once fit- it,s a toolless conversion back and forth. By the way - i also extended the barrel for threads. There,s a video

[@1lovesoni]

@@STEINBVG Yes, I have to punch the pin out each time (along with removing the trigger guard because it's also a spring that tilts the barrel). I've gone back and forth a few times now, but I usually prefer to keep the threaded .22short barrel on it most of the time.

[@STEINBVG]

@1lovesoni Ok. I see. I guess not as convenient as my Colt 1911 or Glock drop in aftermarket conversions. And now my little Astra. But i doubt i will shoot much 25 acp - damn expensive. Just wanted to know i could do it. Thanks for the info. I would like to have this Beretta for a collection. Always loved it

I bought a similar sized gun called "the looking glass" when I was a kid in the early 60's. Mine even had a grip safety. It was a rusty pile of junk with no barrel and some of the locking lugs broke in the frame. It was the first gun I stripped and reblued. We had no Internet to find spare parts so I could only do so much back then. Cute little guns those Astra's.

[@STEINBVG]

Yes. Now I am able to find some odd parts for old projects. Love to return them to working order as much as build new things. Also learn more and more ideas for future reference.

It’s sad u would even bring up that shit gun in the presence of astra cub

Спасибо большое. Очень приятно

@@STEINBVGне буду кривить душой,поверьте за вашим трудом не менее приятно наблюдать, очень познавательно и довольно таки не плохо развивает,я хоть вижу как это все устроено и работает, 👏спасибо

[@Manuel-un4vm]

I tried doing this but got crazy with the dremel and i have all kinds of feeding issues. I don't even know how but my .22 short mag doesn't even lock in anymore. I might just buy another one in .25acp. I think .25 to .22 is easier than .22 to .25

[@STEINBVG]

Sorry to hear it. Not sure where you went wrong. Hope you didn,t do irreversible damage and it,s fixable.

[@Dchannel111]

How much?...

[@STEINBVG]

I don,t sell my work. But I give away the ideas. Thanks

[@hecker2104]

@@STEINBVGmate can i ask did you use same magaine for .22 and .25 ???

[@STEINBVG]

No. 25 mag is different. Typical conversion is a change of slide/barrel and mag in any gun.

[@hecker2104]

@@STEINBVG so mate you changed magazine or you mod .22lr magazine for .25 ???

[@STEINBVG]

Yes, when you switch between the calibers, you use different mags. 22 short mag can,t be modified to fit 25
