Double damages CNC!

My .45 ACP long slide doubled on me while shooting in the shop a few days ago, I looked all over the ceiling and saw nothing, the door frame into the back room where the bullet trap is and didn't see any new holes, so I gave up looking.

The next Monday morning my employee asked if I'd been shooting, "Yeah I was Saturday" I said.
He showed me where a bullet had hit one of the lathes keyboard frames.

Total $401 to replace that.

So now I'm wondering what to do, the trigger is 4.2 lbs and very short and crisp, a sweet shooting gun except now for this problem. I do know I won't be shooting it in the shop anymore, nor is this the first handgun that's done this, a P-08 doubled on me once and put a hole in the roof.
Is the remedy bending the leaf spring, I mean, is that enough? This has an aluminum alloy trigger so it shouldn't be trigger bounce.
Thanks,
parts

A sear with a secondary and rounded hammer hooks can, if overdone, be the cause, too little engagement. Check for short pre-travel, which is also a contributor. A short sear is also a possible reason with that high a trigger pull.

All the parts are new, but I think I did have a trigger with reset tabs and maybe the short reset was caused by that. I'll adjust for a bit more reset and shoot it with a live round over a dummy round, if theb hammer falls I know.
Thanks Log.

Too little pre-travel and really close over travel is a great condition for doubles and more. If reset is close, from too little over travel, just a slight relaxing of the trigger finger after firing the recoil will rock it enough for your finger to bump the trigger. It happen so fast it can be confusing.

Jerry Miculek has emptied high capacity Para's and stayed on target by mastering trigger bump.
