I have see advertised on differnt sites ammo for sale and some say what the feet per second and the foot/pounds of energy is for that round.
What would be considered an average foot/pounds of energy for a 9mm round.I have two 9mm pistols, one is an original Colt Government model in 9mm, its about 20 years old and I have a new CZ75.Ive shot ammo with 345 foot/pounds and 430 foot/pounds in my CZ but would 430 be too much for the older Colt.
Any one got any experiance in this subject?

It's not the velocity or force generated, but rather the pressure generated that dictates whether a particular load should be shot in a particluar firearm.

I would be comfortable shooting any non +P in the 1911, and the CZ should be able to handle any standard or +P load.

Bloke, I agree with Red-leg, although, I think the Colt should be able to handle +P just fine.  You might put a heavier recoil spring in.  However, if you have no tangible reason to shoot +P, don't bother.
