Again my search abilities are challenged!
I cannot find a single big bore airgun that is not a rifle but a handgun. Well, except the Girandoni repeating air pistol:

Do you know some commercial maker for big bore (say, around .5 caliber) air handguns? I Or some homemade projects maybe? cannot believe I am the only one would would like make/buy/shoot one

Not 50 cal but there's
Dennis Quackenbush (who also makes a
0.375" shot pistol) and Gary Barnes who makes them in
45 and
32.
The above are relatively expensive customs though, there are also high-powered 0.22" multishot pistols like the
AR6 and the
FX Ranchero more readily available.

Gah the Girandoni guns for their time were just.....wow. The craftsmanship not to mention the engineering with period materials and tools is mind boggling.
Brilliant stuff I tell you.

Correct, but that was also the problem. Brazing and such, as well as good seals were issues back then. Though they are still good designs..

A few years back, (1990) an English fellow by the name of John Bowkett, made a pcp style pistol that fired .495" roundball.
Stunning craftsmanship with superb styling. 8)
Charged to 2500psi, it would flatten said ball utterly at 25 yards.

"English fellow"? Try "living airgun legend"

I suppose if you are on that side of the pond, you would be more likely to know the name and the work.
Unfortunate really, his custom works are definitely worth seeing.

Didn't know the name, being new to the hobby...
You didn't provide a link.... it was a test to see if I could do basic Googling, right !?
If found a few about
Mr Bowkett and his work, But none about his handgun.
Your not the only one,
I was pretty sure about that
i just bought a shock pump for my new projects, a series of pistols/handguns ranging from .22 to .60 cals!
A series,
wow...
Back from the Home Depot, I have just bought some tubing, so my very first experiment will be a basic .56 launcher (9/16" ball bearing) with a ball valve as a trigger, just to familiarize myself with the pressure... I hope to go close to 400psi, let see if I shoot my eye off...
But first I need to finish those tax income papers...

Yep, I agree. For some practice projects when I get my lathe (probably lathe/drill/mill combo).
I'll make two pistols, .378 cal, homemade QEV with hammer valve, pumped to 300 psi for multishot. Or perhaps one QEV-hammer and one purely hammer.
Just got to do some tests to find a reasonable size for a chamber..and get the bloody lathe
Edit: I found
this.
Is that it? Pistol carbine.

No, nice little carbine, but not what I was referring to.
I couldn't find a picture online of the pistol in question. There are a bunch of Bowkett creations (pistols and rifles) in a Guns&Ammo article. It's in the 1990 Annual.
I'll see if I can scan and crop some of the pictures to post later.

The pictures of course, don't give justice to the mans work, but you'll get the idea.
Good stuff indeed!
Edit: Sheesh... open the pictures to look please.

JSR, those guns are beautiful, just pretty expensive.
