Unintentional Double tap

[Tunachaser]

Recently at a local steel match I had an unintentional double tap.  Shot the rest of the match with no more problems BUT It is a concern.  The pistol is a Bull Shadow with a Cajun hammer and a Cajun adjustable sear and a 8.5# main spring and about 8K rounds fired ( a wild azz guess).  Could a heavier main spring help or replace the sear and/or hammer.  Not sure where to start.  Thanks in advance.

Check your Sear Spring. It might be too weak to reset the seat. 
 

Next, I would check your hammer and sear itself to ensure there’s no rounding of the material. Should almost be a sharp edge.

start from the simple .

check spring  tension  of the "trigger bar". this area must be clean and light lubricated.

next what SouperMan say.

It could have been a bump fire if your grip was not good.

As Amra86 just pointed out, was it a double? IE two shots with one trigger pull, or one intentional and one less intentional IE one shot, perfect finger and trigger reset and the recoil of the gun touching off the second shot?

One pull two shots.  I'm going to get a new sear spring and check the hammer hooks and sear edge at that time.

 

Thanks and I will report back after the parts arrive.

It's like catching 2 tuna on one hook

I had that problem in the past.

 

If you have a trigger with post travel adjustment, increase the travel a bit more, past the trigger break point. Even when its set nicely to avoid hammer and sear contact on manual decocking, a bit more travel ensured I didnt get double taps on a single shot.

 

And what all of above mentioned.

Adjusting the over travel screw seems to have done the trick, thanks coolbox!

It’s always a good idea to back the overtravel setscrew out at least 1/2 to 3/4 turn more than the minimum required.

 

The gun still runs when it’s filthy, and when the springs wear… and you really won’t shoot a stage any different.
