I noticed there was a discussion on bullet setback due to re chambering the same round over and over, so I figured to post a solution here so everyone could see and comment as to if this will help prevent it.
After cleaning my semi auto I load the mag, then I lock the slide back, insert the round directly into the tube, then release the slide, thus there is no chance of the bullet getting set back. Then replace the mag.

Exactly. There are only a few pistols where that loading method does not risk breaking the extractor.
Your concern is a valid one though and here's a way I teach to handle it.
1) Insert magazine
2) Pull slide to the rear
3) Slowly let the slide move forward, stripping the top cartridge from the magazine, and moving it into the chamber.
This type of loading is an administrative task and the technique isn't used anywhere else.
Be aware that some ammo/gun combinations are more susceptible to setback than others.

Oh snap! I never thought of that! See, thats why sites like this are a good thing.
How is the extractor affected on the Glock and HK to doing this??
In general, leaving aside gun makes ....... the pre-chambered round approach means that as the slide closes the claw has to whip out fast to get past the cartidge rim and then settle back in front of it. The ''mag stripped'' round will be pre-engaged with extractor so no sharp trauma.
Extractor design will have some bearing ... a cast internal like some 1911's is IMO very succeptible to this trauma whereas I reckon my short external on my SIG is pretty tough - even so, being short it gets one heck of a jolt if having to get round a pre-chambered round rim.
The ''slow feed'' Randy mentions can be fine and it will reduce that feed ramp trauma on bullet but there could be instances where the lack of ''slam'' does not quite make 100% battery - maybe 99% and so potential for a failure - depends on the gun and the ammo in use. The extractor still has to be fully past the loaded round case rim.

Some good points to ponder, will change my method of chambering the round, thanks
FYI this is commonly known as the "Bubba Load"
You all have just about totally covered this with a blanket. About the only comment I can add is that my CCW gun the HK is not fussy about the drop in the round trick, but my son's 1911 platform it is indeed a real bad idea.

Many external extactors pivot horizontally and can deal with this - Ruger specifies it as the recommended method to fire one shot at a time in their centerfire autopistols.
1911 internal extractors however - while they do have some flex in them - are not designed to pivot at all: the round is supposed to be fed up into the extractor claw from the magazine. This is where you really have trouble with "bubba loading".
My GSR for some reason has a really big issue with setback. Any time I cycle a round out of the chamber it goes into a pocket on my range bag. Next trip to the range, I blow off all of these "barney" rounds so that no round is chambered more than two times.
LOL! Good one.FYI this is commonly known as the "Bubba Load"
The lever on the side of your gun is a slide lock, not a slide release although it can serve as that function. The proper way to release a locked slide is to pull the slide fully rearward while holding the slide lock down. Some guns will automatically relax the slide lock when the slide is pulled to the rear.
It was past military training that taught the method of dropping the slide to battery by clicking on the slide lock lever. Same military training that taught us that the 45 Automatic will pick up a 200 pound man six feet in the air and slam him to the ground if you shoot him in the wrist.
In addition to bullet setback and a broken extractor you could also have a slamfire. Those are fun.
Tubby45, have you ever been to an IPSC match?
No, I just do IDPA locally. Don't have time to travel to shoot. Wish I could.

My Glock's "Bubba load" very easily BUT My Kahr PM9 will have nothing to do with it. I tried it just once, and that was enough because it was clearly evident but the lip of the round I though I was going to leave in the chamber, that is wasn't meant to happen.

My GSR as well has this issue big time while oddly no other 1911 I've had has it as to such a degree. The GSR will jam a round up good in just two or three re loadings of the same round. It makes no difference what magazine I use either be it stock Novak/ACT or Wilson or McCormick mags.
GSR have an external extractor but I would not feel comfortable chamber loading a round by hand for fear of slam fire. Traditional aka 'Classic' Sigs though can handle this as I long ago was told toward a P226 I used to own.
What I do with my 1911s is ride the slide forward slowly as described earlier by another countering the recoil springs pull to slowly strip a roundoff the mag and set it slow into the chamber.
