Guide to properly polishing to smooth the action of the slide

Does anyone know of a decent guide to smoothing out the feel of the slide on a gen4 ?
Ive tried a lot of searches but as soon as you mention polishing or smoothing all results are for trigger mods. I am not trying to affect the trigger at all or change the amount of force required to cycle the slide. I would just like get the slide to ride a little smoother but not looser, without waiting until ive shot a few thousand rounds through it.

Im new to glock and before I start changing things I figured I should ask the experts.
Any good links ?

Seriously, how long is it really going to take to shoot a couple thousand rounds??? One year? If you can't average 200 rounds per month to while learning a new pistol platform, why buy it?

All that aside, it doesn't take thousands of rounds to smooth out a Glock - it happens in a few hundred. Put away the dremel and shoot the gun, at least then the gun and the shooter will get polished.

There is a product called "JB Bore Cleaner" that will do what you are looking to do without harm, it will not embed. Just put a dab on the inside the rails and work it back and forth until you like it.

Thanks, Ill check into that.

-- to clarify -- I shoot anywhere from about 150 to 350 rounds a week across many different calibers and platforms. I tinker with all of my firearms, just as I do with my cars and bikes. I had a glock 23 for a few months a while back but traded it and just picked up a new gen4 glock 20 and a kkm standard length barrel for it. Looking forward to shooting it tomorrow.

Nothing wrong about treeking to make it work better , but you are wanting to start in the wrong place. If it's a glock 20 you wanting to treek you need to be reloading for it on a 10mm that's the 1st major thing you need to accomplish.
Polishing anything other than trigger components is a total waste slide and rails are so loose theres nothing to be gained.

1) You have what is called a "pre-conceived notion".
2) You will be on what is called "a fool's errand" if you pursue this.
3) Luckily there is a cure.
4) It is what's called "shoot the damn gun".

:D

Ive used jb bore paste and kroil myself. OP asked a question . Just wanting to work on his pistol. In return he gets a bunch of smart ass remarks from the keyboard cowboys. If any of you have actually built a pistol (polymer80) than you would know how everything works together maybe then you would understand how minor details can have a big impact.
 
#14 ·
Big impact? How?

I have built the p80 as well as other guns, computers, and inserted a LSx engine into a Mazda, and GM small block V8 into a Porsche, and changed turbos on other cars, etc, etc... and I live in a 100 year old house, where nothing from Home Depot fits. I've spanked my share of monkey till it hurts.

FREE advice here: From experience, I can honestly say that the factories have much more wealth, professional operator/ninja consultants, data, and experience to do it "right for the vast majority of the population in the widest range of usage" at their disposal, whereas a tinkerer is just fooling him/herself in thinking he/she can finally get it right the 5th time for that narrow range of use.

I’m sure you are a master at everything you do . Including tooting your own horn. I don’t care what you say you’ve done. That means nothing on the internet . These forums are full of people like you. Clearly you don’t know sh!t about guns and tuning them . I have built worked on and ransom tested enough guns to know. You are flat out wrong. If you want to blast silhouettes at 7 yards this entire conversation is irrelevant. Fact is - Glocks are mass produced to be cheap. That’s why there is such an aftermarket. This is a waste time.
No hollowing out a kit doesn’t make you a gunsmith , however working out problems to make a polymer 80 run smooth May teach you a thing or two. Clearly you have NOT built one. Or any firearms for that matter. Ransom rests don’t lie - Glocks can be improved upon . This is a fact. I shoot at Sandy Ford in Streator Illinois I’ll invite any of you know it alls to meet me there and see what I’m talking about. Maybe you are more of a visual learner. You bring your Glock I’ll bring mine well lock them in the ransom and I’ll show you exactly what I mean.

I've gotten into the habit of "pre-breaking in" guns before taking them to the range.

To smooth out the slide (as you mention), I clean and lube and assemble the gun without the recoil spring assembly. Then while I watch something on TV, I'll hand-cycle the slide 200-500 times or until I feel that it is as smooth as I want. Then clean, re-lube and put the RSA back in.

Taking the time to do this "hand-break in" routine has resulted in me having far more firearms that have never had a failure of any kind.

I’ve seenlapping compound applied to the rails and the slide worked repeatedly to mate the surfaces on high end 1911 builds.
Or they could
“Just shoot it” lol
Glocks and lapping compounds are not needed. They are already loose. and only have 4 points of slide guided contact. JB Bore paste or other fine non embedding compounds mixed with oil 50/50 on tight slide to frame fit 1911's are an option but you have to flush every bit of compound out afterwards. I would have a stripped frame and slide to do that on a 1911. Les Baer won't lap his guns and they are tight.

No, you sir, are clearly enamored of your own ability to make things better on a very limited scale, and range. Perhaps your one or 10 p80 guns are impressive on the Ransom, or my car can be impressive in the 1/4 mile at my local track against other hackjobs, but to the universe, that is irrelevant, and worthless. Do that 2000 times a day on a consistant production basis, make 99% of them reliable, then that would be impressive.

Smothing the slide movement will be equivalent to putting a coffee can on your exhaust. It sounds faster, and feels good since you can claim it, but will make no fffing difference at all.

Nothing will smooth it out better than shooting it.

Does it feel gritty or just clunky? The slide "clunks" a bit as the barrel locks into the slide.

Maybe just make sure the gun is unloaded, hold the trigger back, and work the slide over and over and over again.
