-JCN- Posted February 17, 2020 Share Posted February 17, 2020 Hi guys, I was used to Glocks where you can put any slide on compatible frames because the fitment is so loose. I am shooting CZ shadows now and I think I effed up by mixing slides and shooting 20,000 rounds. Now the slide has a little up and down “play” when I push on it, that a new one doesn’t have. I’m sure it only affects accuracy minimally for this sport... but wondering if there is something I can do to tighten the fitment of a worn frame to slide. Or just deal? Is there such a thing as wearing out the frame and did I accelerate it by not being generous with lube (sandpaper effect)? Just trying to get a context of how long a competition gun should last. I’m at 20,000 rounds and that doesn’t seem like a lot from a competition perspective. Thanks in advance. Link to comment Share on other sites More sharing options...
jwhittin Posted February 21, 2020 Share Posted February 21, 2020 Is it possible you didn't catch it when you first mixed the slides? Unless custom fitted to tight tollerence there will be movement. And yes it will loosen with use. There are a lot of factors. Many smiths offer slide tightening service. Link to comment Share on other sites More sharing options...
jwhittin Posted February 21, 2020 Share Posted February 21, 2020 (edited) And for a 5" barrel, ever .001" of slide to frame movement translates to .18" at 25yrd. This is worst possible case but likely much less. Your call if you think it's worth spending $200 to improve.

SGT_Schultz Posted February 21, 2020 Share Posted February 21, 2020 Never mind the fit of the slide to the frame. How does it shoot? Link to comment Share on other sites More sharing options...
waktasz Posted February 21, 2020 Share Posted February 21, 2020 The sights are mounted to the slide, so the play between the slide and frame doesn't affect accuracy at all Link to comment Share on other sites More sharing options...

The fit between the barrel and the slide is what matters. OP, again, what kind of accuracy is your pistol producing today in capable hands?

OP, again, what kind of accuracy is your pistol producing today in capable hands? That’s a good idea. In the meantime I received a replacement optic (lens cracked) and sighted in the well worn gun and the new one. I’m guessing that the accuracy of both is still under 1.5” at 25 yards. I was using 1” pasters and a 6 MOA dot from a bench rest. But good idea. I was just sighting them in, so stopped when I was clustered close. I can just do a 10 shot test of each one separately and measure the spread. Link to comment Share on other sites More sharing options...
-JCN- Posted February 22, 2020 Author Share Posted February 22, 2020 Well, I guess that answers that. Thanks Shultz for the real world data request! Loose gun best 4/5 group at 25 yards is 1.33” and new, tight gun same thing at 25 yards is 1.56” so the loose one still is as good as anything else!

So I appreciate you taking the time to help me help myself! I was right only inasmuch as I asked the right question: how does the gun shoot? Hopefully you've learned from this whole deal the most important truth in shooting: the bullet never lies. It means that you can get wrapped around the axle listening to all the so called experts and all the internet bulls#!t about slide to frame fit, or you can shoot the gun and see what IT tells you.

jwhittin Posted February 25, 2020 Share Posted February 25, 2020 lesson learned. I should have asked more questions. Glad you got your questions answered. Link to comment Share on other sites More sharing options...
