what would be the biggest differance between sonsonic and regular ammo in a unsuppressed pistol, and will it funtion right
Comments
No advantage to shooting it unsuppressed that I am aware of. I shoot a lot of it suppressed but I load my own.
Unless I am wrong it is usually more expensive then "standard" ammo. If you are just looking for plinking ammo and you can find SS cheeper there is not reason not to shoot it.

a. Even unsuppressed its still quieter than ordinary (ie 115 or 124 grain) 9mm ammo. That might be an advantage, I guess.
b. You *MIGHT* be able to find it cheaper than other premium 9mm luger rounds (though probably NOT).
c. MOST full sized guns will run the 147 grain ammo just fine. Some won't because of bullet shape and/or overall length. There is only one way to find out. . .
d. Terminal ballistic improvement is questionable. I strongly doubt 147 grain ammo works any better than say 124 grain, etc.
Edit: For what its worth, I've only tried 147 grain ammo in a few different guns, but the ammo I've tried ran fine in SW99, Glock 17, CZ-75. Again, it will *probably* run fine in any of the modern design full sized autos (ie Sig, Glock, Beretta, etc). You may have problems in compact guns or in older designs, especially ones that don't have feed ramps.
In terms of recoil, usually the heavier the bullet the MORE the recoil. I'd say there actually is a little MORE recoil with 147 grain ammo, but its a fairly small difference, and in any case, we're still talking about 9mm luger which has intrinsically low recoil anyway.
One other potential difference relates to use of the round in CARBINES. In theory, heavier bullet weight might help cycle the action of 9mm carbines with picky/stiff blowback actions (though in my experience most 9mm carbines work fine with ordinary 124 grain ammo). Also, while pretty much none of the 9mm carbines give you pinpoint accuracy, you might expect slightly different (I'm not sure if it will be better or worse, probably worse) accuracy with heavier projectiles, depending on carbine barrel twist rate.
I do, however, shoot a lot of 9mm and I have to say that the only, ONLY, problems I have experienced with my pistol have been while trying to shoot 147 gr ammo.
But maybe it's my own particular gun.
I don't think I'll try anymore 147 gr though.
I have shot quite a bit of 147 grain ball ammo, and have never really had problems. I like it because where I shoot the feedback od the sonic boom off trees and walls is almost as loud as the shot. So it cuts down on noise polution.
