I tried to search, but for some reason the function seems to be disabled for me. Anyways, what (aside from H&K P7's) model of autopistol's have fixed barrels? Are there any aside from the H&K P7?
 
And dare I say it!?.......

.....Hi-Points! Actually, I had a C-9 and can't fault it. Put a couple thousand rounds of Wolf thru it without a hiccup. Now I wish I kept it for a car gun.

Almost any pistol in a cartridge less that 9mm can have a fixed barrel. In fact the number of 380 and smaller caliber pistols that don't use simple blowback are pretty limited.

For the high pressure rounds like 9mm, 40S&W, 10mm and 45, the number of fixed barrel pistols is also small - the already mentiond HK P7, HK P9, Benelli B76 and a few others.
 
In 9mm the P7 and HK VP70 come to mind.
in less than 9mm a few popular ones are;
Sig P230/232
CZ82/83
Walther PPK and all clones
Sphinx AT 380 (CZ82 clone)
Makarov
 
The overwhelming majority of handguns .380 ACP an lower (in terms of power), Mak, the above mentioned, Hi Point.
 
Every straight-blowback-operated pistol - which in turn is almost every .380 ACP and lesser cartridge - I know of has a fixed barrel. Most of them follow the Browning 1910 design with the barrel rigidly affixed to the frame and the recoil spring encircling the barrel.

Pressure isn't the determining factor in whether or not to go with a straight blowback or locked breech. Recoil impulse...that old equal/opposite thing that
punches the bullet also punches the slide/breechblock is the thing. Whether it's straight blowback or locked breech/recoil operated...they all function with pretty much the same set of dynamics. Force forward equals force backward.

The .22 rimfires generally operate at higher average pressures than the standard .45 ACP...but .22 autos are straight blowback in operation. Even .22 magnum autoloaders are generally straight blowback.

9mm and .45 caliber High-Point pistols are straight blowback, but have massive slides and strong action/recoil springs to control the breech opening.
Others use some sort of means to retard or delay the event...such as the HK
P7. The .308 caliber HK 91/G3 employed a roller delayed blowback system in which two spring-loaded rollers engaged into keyway-shaped recesses in the receiver in order to retard the bolt until the bullet exited and pressure dropped to a safe level.

The P9 doesn't have a fixed barrel...

Um, I'm pretty sure it does. I know that the P9S does, at least, and the P9S is just a double action version of the P9. To my knowledge, both use a roller-locking delayed blowback action, just like the H&K rifles, and both have fixed barrels.
