this is a complete newbie question but i'm going to ask it anyway, better safe than sorry.

I just took apart my CZ 75 SP01 and after i put it back together i pulled the slide back like i was going to #### it and i noticed the barrel moves backward slightly. Is that normal on pistols or do i have a problem? I'm pretty sure it is supposed to happen because the barrel is not fixed to anything, it is just held by the spring inside the slide.

Anyway be gentle
Thanks
 
this is normal in all firearms that use "short recoil operation"

when a round is fired, the barrel moves rearward slightly, then the slide, ejecting the casing and the slide returns closed, chambering a new round. the barrel moves foreward locking the action closed.
it is normal
 
This is normal buddy! every pistol has its own type of movement of the barrel, if it shoots straight there is no problem generally speaking. But don't rely on me, there are much more knowledgeable people here, and I haven't done any pistolsmithing as of yet!, I just work with them as a tool to keep me alive.

I am new to firearms, and after a long winter break noticed the same thing with my SP01. I couldn't remember seeing it before....but then I was still blinded by the new and shiney.

I thiought I had reassmbled it incorrectly, and was going to post this same question.

I decided to wait until I shot an IPSC match last weekend in the COLD, and the gun functioned flawlessly (best of the ones there), so I figured all was ok.

Nice to get the confirmation here. Thanks for asking for me.:wave:
 
The short distance in which the barrel moves with the slide allows time for the pressure to reduce and the casing to contract slightly before extraction. If it didn't do this, the casing could rupture, or stick in the chamber and get torn apart by the extractor. There are some other methods of locking the breech on pistols, but the tilting barrel type as on yours is the most common.

Direct blowback firearms, typically in smaller calibres (.22, .32, .380) hold the casing in the chamber with the weight of the bolt / slide, and the strength of the mainspring.

ETA: it's nice, by the way, to see people asking total newbie questions ... 'cause it shows we've got new shooters joining us! :D
