Help with disembly of a CZ 75 B pistol in .40 caliber.?

I recently purchased a CZ 75B handgun in .40 caliber and while trying to disemble it I found it slightly difficult to get the recoil guide away from the barrel to take it out....and even more difficult to get the recoil guide to go through the hole below the muzzle on the slide during reembly. Is this normal with these types of handguns? Am I doing something wrong. It is just a really tight fit and when putting it back in, the guide is at an angle and under a lot of tension and it is just kinda difficult...I don't think this will interfer with the operation of the gun....if anything I'd imagine a tight fit would be good, but I'm kind of concerned.
