Default Thoughts on lightening the slide on my c9

So I was looking into it and want to get some feedback on my thoughts. I know that blow back guns act on a good part of their mass to function. So I was think that if I get spring wight on both springs and divided the spring weight by the weight of the slide individually. That would give me a base line to work from I then could increase the spring weights as I lighten the slide to equal the base line I know that it would make cocking the gun harder but I'm not that worried about. What I need to know is where could I take the weight from I remember a thread about there being inserts in the slide of different metals in spots that prone to fail. So let me know what you all think and we'll go from there.

Check this out. It's math heavy, but may get you going.

Thanks for the site I looked it over and I still believe that mass can be cut down by compensating with spring weight and like it says it will be harder to load but I will be going into this knowing that but my question still remains is there an ideal place to remove the weight or a place that I should avoid thank for the site

Default Perceived recoil will be heavier if you make the slide lighter

My C9 and JHP .45 have very little perceived recoil compared to other guns I have shot in the same caliber. The carbines have very light recoil as well. That is due to some extent to the mass of the slide.

You are playing with fire... The weapon was designed a certain way to operate and function the way it does... If you can figure out the proper spring to slide weight ratio.. You still run into the problem of WHERE exactly to remove the extra metal... if you take it off in to wrong place.. BAD THINGS can happen...

That's what I'm thinking. To much in the wrong place and it's goodbye good day at the range and hello bad day at at the hospital ( if I'm lucky). What I was thinking was a long narrow port on both sides of the barrel and sliming down the side straps a 1/16" or 3/64" then milling in some new serration on the front and rear of the side straps the top before the sights. I'm looking at maybe milling off 4 to 6 oz. total what do you all think

I'm plotting to play with fire as well. I'm going to make my JHP shoot 45 super. I'm not doing it to make a 45 super Hi Point because I don't think it's possible to do safely. My interest is in the round. If I can make the HP shoot it, then I can test the round and determine if I want a gun that shoots it safely. Because I understand the gun may fail I will shoot all 45 super rounds from a vice. I think you are risking a gun failure just as I am. I would not shoot your gun as you plan on modifying it with my hands. You can't just hack weight off the slide haphazardly without having some clue how the forces flow through the gun, and expect it to be safe. I'm likely to ruin my JHP, but I don't care. I also will not shoot it with 45 super with my hands. And if it survives the experiment I wont shoot it with 45acp until I have thoroughly inspected it with dye penetrant and a magnifying glass for cracks.

I apply a good amount of Tetra grease to my C9 slide, and it is effortless and slick sliding across the frame.

AFAIK, the top and the areas in front of the chamber to the muzzle would be pretty free of any inserts. Go for an open top slide, like the M9/92 series, and you'd be OK, I think.

If it blows up, don't blame me.

Thats what I was thinking... As long as any removal of material takes place in front of the breech face chances of failure would be reduced greatly.. An open slide Hi Point would be rather interesting to see...
