Can you run 45acp +P ammo in a Colt Series 70?
What about +P+?
Yes. Should not be a problem.

There is not such thing as 45 +P+. That would be 45 Super and not safe to shoot through the 1911.

Your correct, I picked up the +P+ from the .44 mag line right above the .45 acp listing.

You might also want to put a heavier recoil spring in it, 18.5 or even 20 to compensate and prevent too much battering. 18.5 for occasional +P, 20 for a more steady diet and if so inclined, Shock Buffers. Just my .05 cents worth (adjusted for inflation)
