cz 70 slide wont hold back after last shot

[yourfns]

Hi All, I just bought a cz 70 and it fed and ejected flawlessly. The only problem is the slide doesn't stay back after the last shot. This only happens when I shoot it. When it's unloaded with a mag in it holds back everytime. Also it happens with 4 different mags.  I'm no gunsmith but I'm pretty good with my hands. I'm thinking slide stop spring. Any Ideas??

If it happens with all the mags then you're probably riding the slide catch with a thumb. Try shooting it left handed.

Thank you Widge! I'll try that next time at the range.

Always look for a simple fix before busting out the $$$!

Here's a very good thread on another forum that addresses the problem you're having; while aimed primarily at Sig pistols, it's causes and cures are applicable to many others as well: http://sigforum.com/eve/forums/a/tpc/f/150601935/m/749101723
