When I let the slide down on the first round- sometimes with a mag, sometimes without. I get a slamfire as the hammer follows the slide.

I took the frame apart and noticed no undue wear and have good hooks. Once the hammer is set back, you can not pull the hammer up. This only happens on the first round.

I recently resprung the pistol according to 'Tuner's recommends- a 14# recoil and a 20 pound mainspring, but this did happen once on a slide drop with no rounds (thanks to my buddy who did not know that I did not like that). It has never happend in competition.

I will be sending this back to the factory for a revamp (lifetime warranty) but am more interested in what it could it be- is it the spring?

I followed the thread about bending the left spring in, and it did not hlp- how far in should I bend it- should I go to a 21# spring?
 
You should not be letting the slide close on a round without a magazine, that is hard on the extractor.

You should not be getting a slam fire even if the hammer follows, it should be caught by the half cock or safety stop, whichever style of hammer it is.

I do not know what you mean by: "Once the hammer is set back, you can not pull the hammer up."

But something is bad wrong.

Howdy hube,

Hard to diagnose this one without seeing it.

If you're getting a slam-fire from a a slidelock reload, there's more wrong
than a new sear spring can fix. If it happens with your finger off the trigger, the half-cock should stop the hammer before it hits the firing pin.

Hooks are worn to a negative purchase angle maybe...and the mainspring tension pushes the sear away from the hooks. Inertial trigger bounce
kicking the sear out from under the hooks. Half-cock should still stop the
hammer fall.

Check it with one dummy round in the magazine and trip the slide with the slidestop...finger OFF trigger. If the hammer falls, the half-cock should stop it unless the notch has been altered or removed.

Test it again with the trigger pulled. If the hammer reaches the firing pin
stop, the hooks are probably worn and the slide's impact is bouncing the
hammer off the sear. If the hooks are worn, when the hammer resettles
on the sear, it squirts the sear out of engagement, and it could be getting
past the half-cock.

A 23# mainspring is all that I use, and is discourage the use of anything
lighter than 21.

If the hooks are square, and not shorter than about .021 inch long,
try a new sear spring and a 23# mainspring. Check the sear primary angle
to see if it's rounded off or damaged.

'Bout all I can tell ya without a look-see.

Luck!
