Yeah...Technically the slingshot is when you pinch the slide between your thumb and index and or tall fingers. 

I wrap my hand over in front of the ejection port as well.  Pulling to the rear and letting my hand glide along the top of the slide and off the back releasing it.  This clears a stove pipe as a part of racking the slide.

The trick when learning this drill is it feels awkward to do at first unless you rotate the muzzle towards the weak side, potentially breaking 180.

Or rotate your body 90 degrees CW, so that the gun remains pointing downrange (or toward the bad guy).  To make it easy, you DO need to be moving your two hands (and forearms) laterally across the front of your body, in opposite directions, approaching each other, always held close to your chest.

I am gonna guess dred means he chambers a round using the slingshot method, not by depressing the slide stop.

Yes, exactly.

Quote from: Mike_Fontenot on December 15 2016 08:27:37 AM MST(The bulls-eye technique is necessary to ensure that I don't get an inertial trigger pull, because of my very light trigger-pull (2-1/2 lbs)).  So in this case, the firing-pin safety DOESN'T protect me, but that's not important then, because the gun is pointed in a safe direction and it's not a disaster if it fires.

Fair enough; 2.5lbs is light enough that I might have trouble relying on the ledge to prevent a bump, jiggle or forceful sneeze fire.  I am imagining myself responding to a squeeze that light by beating my pistol with a nylon mallet until I was confident that the sear held the hammer securely.  My triggers are all factory. (3.5 to 5.5lb)  My old Vbob did make a trip back to DW to re dress the sear and stop the occasional unplanned double fires.

And regarding the slingshot ... I grab the slide with weak hand, but I rack by pushing the frame with my shooting hand.  I do this because my shooting hand is controlling the direction of the muzzle and I'm not willing to give up a secure grip just to get the slide racked.

In my case, I am still waiting for my first negligent discharge.  When it happens - my primary concern is to have the muzzle pointed in the safest direction available.

If you experience reliability problems in the 1911 platform with 10mm, I suggest you look into making the hammer spring, recoil spring, and firing pin stop modifications I noted.  All of this helps control the excessive slide velocity of the 10mm.

I tried all those things shortly after I bought my Eclipse, but I found that I couldn't get the light trigger-pull that I wanted (about 2.5 lbs) with anything other than a light 18lb hammer spring.  And jamming frequency always seemed to increase with heavier recoil springs ... I used the stock 18.5 lb recoil spring for years (because it seemed more reliable than any other choice), but finally upped it to 20 lb after seeing some battering.  I HAVE been using a flat-bottomed firing-pin stop for years, though.

All I can offer is try different mags.  Mine works with all I have tried though (factory and Tripp).  I have not measured my pull, but it's pretty light.  I put my time into appropriate polishing of internals.

I will say, in general and beyond just Kimber, the more guns a company sells the more complains you can find on the internet.  S&W is regarded as a fine revolver company in general but boy, if you really look at the revolver forums there are plenty of horror stories about their QC.  Some guy received a 357 with  7 shot but fluted for 6, a couple of the chambers probably would have ruptured with normal pressure loads if he had tried to fire it.  I think Kimber suffers the same numbers problem compared to DW  and other lower volume brands.

I break into a cold sweat every time I imagine 9 rounds of 10mm going off in about a second or two ... who knows where that muzzle would end up pointing.

That is something to ponder for about anything(specially cars/trucks). Something else seems to me if 10 people are super satisfied with something maybe 1 will take the time to post about it unprompted, but if 10 people are dissatisfied maybe 1 wont take the time to let everyone possible know about it.Then it becomes kinda pack mentality.

All's I know is that I am very happy with mine If I wasn't happy with my Kimber I would have sold it and bought the new Colt Delt Elite. I trusted mine so much that I carried it several times with me Deer Hunting in WI this year, and loaded with Underwood 180 gr XTP @ 1350 FPS felt well armed. Now that Deer Hunting is over with I still carry both the Colt and my  Kimber for when I take my dog for his 2 daily walks as my 9mm S&W Shield sits on the window sill.
Like I said before if I didn't like the gun I wouldn't own it!!!
