    Hi, om currently running a standard length in my s2 opengun, but i need a longer one to index my czeckmate comp, is there one "inhouse" that i can use? E.g like the TSO or something? I need aproximetly 10mm longer

    QUESTION ABOUT SLIDE LIGHTENING.

    in CZ

    You do not have to lighten the slide on an Open gun if you don't want too.  It will just cycle a tad slower.  I shoot with a guy who had his gun made before lightening because common.  The gun is 12-15 years old and runs like a top.

     

    I have all my 1911 and 2011 Open slides lightened to 10.5 oz.  I have metal removed where it is not necessary, and none in the important areas.  It reduces reciprocating mass.  I spring accordingly.

    Great, I want it to cycle faster (even though i probably wont know if i got better performance out of it)  milled mine to 293grams (including bushing, extractor/spring and firing pin/spring, retainer and charging handle) gonna test out springs when it gets warmer.

    I had my first Shadow 2 milled for an optic when the max weight limit for CO was 45 oz.  At 46-47 oz, the gun was already overweight to begin with for CO (circa 2018 rulebook).  But, since I was shooting it in Production at the time and really liked the platform I bit the bullet and had the slide milled for the optic (SRO) and to reduce weight.  Came in at 44.1 oz w/ optic and empty mag installed.  When I set my second Shadow 2 up for CO, this was AFTER the weight limit was raised so had the option of not doing the slide lightening.  However I had the second Shadow 2 milled with the same slide lightening cuts bc I liked how the lighter gun felt and wanted to keep them both the same.

     

    The cuts look cool, but they do tend to bite the hand if you rack from the front of the slide.  I think I mostly use my optic as a slide racker these days…. 

     

    I would recommend Fire 4 Effect in TX to do the slide milling for the RMR/SRO footprint but unfortunately they went out of business at the end of 2022.  

     

     

    I understand why you guys do it , all good reasons.

     

    But since i run my s2 i ipsc open major and read something about removing material on slide equals less felt recoil - i milled it a bit. Not for looks, but to make it lighter.  Then afterwards i wanted to know how, and how to decide where to mill and how much to remove etc , I know its the wrong order, but i am eager to learn. 

     

    Im in europé, so I cant use companys stateside.

     

    At last but no least:

    I am very happy for all you guys trying to answer my question, thats the reason i like this forum - People takes their time and actually tries to help.

     

    Thanks alot guys!!

    Unless you have a mechanical engineering background (like a degree and practical experience) you're not going to be able to figure this out.

     

    Sorry, but that's just how it is.  If it was so easy that I could give you some equations, there would be no need for a course in engineering mechanics in college.

     

    Not only do you need to understand the formulas, you need to also know how to model the system accurately for the answer to make any sense.  Most of the textbook examples you'll find deal with very simple, unitary bodies.  Not a handgun that has one half that remains stationary in your hands and another half that reciprocates above your hands.

     

    The majority of shops who do these slide cutouts are run by gunsmiths and machinists.  They usually don't have the education and experience to make these calculations and just figure things out by trial and error.

     

    If you really must know, start here: https://www.toppr.com/guides/physics-formulas/angular-momentum-formula/

    Thank you sir, after reading at your link i realised im not that smart, so i must not know at that level, but after some more research i came to the easy answer that its done to make felt recoil more manageble.

     

    Thanks for the help guys

    QUESTION ABOUT SLIDE LIGHTENING.

    Thanks for the answers guys, i know about remowing material to fit in specific Class in us, but i was mainly thinking about why they remove on openguns. 

     

    Jonny, say im not newtonian formula smart, how do I calculate?

    QUESTION ABOUT SLIDE LIGHTENING.

    So, ive been reading a lot here on theese forums about slide cuts/milling for shaving weight. How much does this really affect handling/recoil? Is there some way of calculating? Or is it guessing?

    Open magwell for shadow 2

    in CZ

    Posted

    So, i got this magwell for my s2, but I've seen bigger for both 2011 and czeckmates, is there one with bigger funnel for the s2? Or is there one with really close fit? I haven't found any myself, hence the question.

    Slide racker for shadow 2 slide

    in CZ

    I question the need for a racker.  Only one of my last five Open guns has one.  It is the last one I built as a backup.  I decided to try one.  IMO, it takes more effort and is slower than just grabbing the rear of the slide.  The only time it is an advantage is on a table start if you don't have a thumb rest installed.

    In general you are right perhaps, but specifically regarding my gun you are wrong. My slide lacks serrations due to being fully milled to remove weight.

    I can definitely see a use for a racker.

    Does anyone know of a slide racker that replaces the shadow 2 rear sight?

    I thought the Armory Craft one would fit but on their website it says it will not fit.

    I designed one, it's on thingyverse. I run it on my shadow 2 open

    TSO 3D Printed Magwell

    I wanted to show off something I've been working on. I really don't love the design of the factory magwell on the TSO. Looks wise it's okay, but it sure is tiny. I've had my TSO for a few months and the magwell is already completely chewed up. I've been working on a 3D printed design for a better looking magwell with a wider opening. Say what you want about 3D printed parts, they aren't bomb proof, but hold up better than you'd expect. They're also cheap to make if you own a printer, so replacements are easy to come by. If you know CAD you can also make super custom items that are spec'd exactly how you like them.

    For the life of me I could not get good lighting for this picture, but I'm happy with the look. A good eye might notice a 3D printed mag release and thumb rest, both my design as well. Anyone else running 3D printed parts on their race gun/ rig? I'd love to see some of the stuff people have come up with. You really can't beat the customization that a 3D printer affords. 

     

    Are you sharing this STL?

    Time had come to make the compensator, I found a suitable chunk of aluminum in the back of the shed and started milling.

    I tend to build things on the go, no cad drawings here just a caliper and some scratchings on a piece of paper. Here I am using the pistol to find the right angle for the comp profiling.

    Here is the compensator after some finishing touches with the sanding paper, I don´t want to over do it at this point before I have test shot it properly and found out what the dot movement is like.

    Here is the comp in place on the gun.

    While waiting for a 3.3mm drill to arrive so I can make the threaded holes in the frame for the sight mount I borrowed a rail mount from a friend, I got permission to weld a simple thumb rest to it.

    Here is a pic of the first shot fired with Major ammo, the ports seem to be working so I will try to find more time for shooting this weekend and try to make up my mind about it. I have a RTS2 sight on its way so with a lower mount and the RTS2 sight I think this will be a sweet shooter.
