The chance of you limp wristing the 83 are slim to none..literally. My son who is 8 and 60#'s shoots both of my 83's with all kinds of ammo and has never had a problem...in over 500 rounds. Then again hes very strong for his size
The situation you describe sounds like a union of little problems causing you a bigger problem. If you have a little too much friction at many points ..it will cause FTF's.
The feedramp can be smoothed out like Walt described (thanks Walt)...you can finish it off with scotchbrite pads. You dont need it to be mirror smooth..just smooth to the touch...your feedramp cant tell the difference between bullets or your fingers.
Take you mags apart and smooth out the tops of your followers..the plastic thingys that push the bullets up.
Again not rocket science..just make them smooth and even.
Question? When you put bullets in your mags do you feel friction or roughness on the feeding lips as you load them?
If so...take some scotch brite to the "underside" of the lips where they contact the bullets...just a little to make sure they are smooth....This helps on brand new mags at times.
Put a tiny bit of oil on them when putting them back togethor and wipe dry when reassembled.
Now a couple of other tricks..K? When you have you gun apart..turn you slide over...youll see a little smooth raised area on the bottom of the slide behind the ejection port...right under the firing pin....see it?...Its about 1/4" wide and 1 1/2" long. This little strip is where the top bullet in your mag 'rubs" as the gun shoots and is waiting to be chambered...make sense. The forward edge of this strip is what actually takes the round from the mag and sends it into the chamber. The bottom of this strip should be very flat, smooth and even. You can give it the same treatment as your feedramp...just dont go bonzai on it. Just smooth to the touch.
Now a couple of other suggestions. Your slide has a certain timing to it. When the round is fired, when all is right with your gun, the slide comes back and ejects the fired round.
The recoil spring is compressing and building tension. The tension has to be just enough to take up the energy from the slide and stop it with out letting it "slam" into the frame..and send it back with enough force to strip the next round from the mag and chamber it. While the slide is coming back your top round is rubbing on the slide as described earlier..causing friction..not much, but its still there.
My point is your recoil springs have to a "good" tension and so do your mag springs. You may have a slightly weak recoil spring and/or strong mag springs putting force on the slide that the recoil spring cant overcome.
Just as a precaution..you can get new springs from CZUSA...a couple of each is good insurance, you have spares that way.
Ok...your feedramp is smoother, mag followers are smooth, mag feedlips are checked out and smoothed if needed, mags are clean and slightly lubed, the little steel area under your slide is smooth and slick, We are gonna assume your recoil/mag springs are good and your gun was cleaned and properly lubed....you should have NO problems. If not, get a set of springs from CZUSA...recoil/mag and see what this does. I use BreakFree CLP for lube. It works pretty good.
Shoot well and let us know how any of this works.......
