I recently bought a used stainless Marui Hi Capa 4.3 that I will convert to a 5.1 . I have a shooters design CNC metal slide that I want to install on the 4.3 frame. While test fitting the slide on the frame, I noticed the slight wobble and play in the slide movement on the frame. What is the best and safest way to tighten the slide on the frame. I want to get the tolerances down to a minimum. I haven't been able to find any postings on how to do this safely without cracking or breaking something
I don't know how to help you with your problem, but why would you buy a 4.3 and convert it to a 5.1 anyhow?
Why do you want to tighten it up???

You can squeeze the slide in a vise and/or peen /swage the rails done. Either one of these can destroy your frame or slide if you are not careful. It does not take much to move aluminum so you will want to take things very, very slowly. You can buy tools to this but they are more expensive than buying a new slide or frame.
I was just wondering. I have seen some custom Hi Capa's at a local shop here in town. One I looked at, the aluminum slide fit so perfectly, no play or hardly any, but the slide still moved freely on the frame. Could this be a result of perfect matching of slide and frame? The frame was a stock TM frame.
I thnk the problem is that your frame is not new. If you find that your new slide is wobbly on your used frame then it is probably because the frame has been worn down enough to create space for the slide to wobble around on. New stock frames should be really tight with new sd slides, but yours is used. A wobbly slide is inevitable after some use. You can remedy the problem by either trying the method with the vise to tighten or buy a new stock or aftermarket frame of higher grade aluminum. I would do the latter as the former is risky.
