Python trigger reset

[jwxspoon]

I traded for a Colt Python from a member here a couple of months back. Didn't have a chance to use it until yesterday. This weapon had the hammer bobbed and trigger jewelled prior to the trade, so it is DAO. Cylinder locks up tight and appears to function correctly.

Fired 3 cylinders of .38 special smoothly. No problems, very accurate.

Fired one cylinder of Magtech .357 Mag, 158gr jhp. Trigger reset problems after the third round and on each round thereafter. Basically after releasing the trigger it stays back and requires a little push to go back into position.

After firing the 6 .357 rounds, I went back to .38 special. Same results with trigger reset as the .357

Any ideas?

Sounds like Murphy has been inside your Colt. If the hammer was bobbed what else was monkeyed with????? The trigger return spring possibly??? Wonder what else may be hiding inside????? Sounds like your ready to meet your local friendly Gun Smith and have him/her go through it and make right anything that was made wrong.
That's one reason I stay away from modified guns unless I'm prepared to replace everything that's inside......

Pythons don't have a trigger return spring exactly.
At least, not in the same sense that a S&W has a rebound spring.

They operate off a part of the big V-Mainspring that also powers the hammer.

More then likely someone lightened the mainspring too much by bending it, and messed up the trigger return part.

After a little .357 action, heat expansion caused binding in the lock-work the lightened spring was unable to overcome.

I see big dollar signs on the horizon!


BTW: Bobbed the hammer & Jewelled the trigger on a Colt Python?
Mercy! Mercy!

Yeah. When I worked out the trade, I was told that the trigger and hammer were reworked for DA shooting competitions. I would much prefer a stock configuration, but I told myself I would replace the barrel with a 2.5" barrel and have a nice carry weapon if all worked out. In any case it is a unique weapon, which is what I was looking for in the trade.

Python work is $$$$.
There are just not a lot of guys who can work on them and not screw them up.

They are hand fitted from the get go.

And sadly, there are getting to be fewer of them with each passing year!

Take off the grips and look at the V type mainspring.
Is the top leaf straight or "raftered" with a downward bend? The quickie "trigger job" on a Python was to stick a rod through the spring and cock the gun, using the leverage of the hammer to bend the spring down and reduce tension. Even the Colt Custom shop did that, Don Tedford used a 1911 firing pin to give him just the right bend.

Or does the spring show grind marks?

Well, reduce the tension up and you reduce the tension down, and tension down is what powers the rebound lever to return the trigger. (Gough Thomas explained the operation of the Purdey sidelock by saying that if that were not so, as commonly said, you could build a perpetual motion machine with V shaped springs.)

A new spring is about $10 from Brownells.

If it is not a reduced spring, if something were done to the rebound lever or trigger, say; you are really hurting.

Give it a good cleaning first, the v spring return action was not the strongest and may be gummed up some. If it's the spring, Brownells has them (under $11). You might see if it will work as a drop in (you or a smith will need one any way).

Oops, see Jim has already posted the Brownells info

Dropped off the weapon at my local smith today. We'll see how it goes.

Picked the weapon back up, only $25 from the smith. Dry firing the weapon is seems to be working very well.

Glad it's working, I love this thing... it's been like having a sick kid.

What did your 'smith say was the problem?
