I was wondering if anyone had any tips on how to smooth out the DA trigger on a GP100.

Dry firing, lots of it...:D

The whole trigger assembly comes out pretty easily, but I wouldn't suggest messing with it unless you've got some experience in that regard. Polishing an action isn't particularly difficult, but it's pretty important that the angles not be changed.

I took apart the entire gun to do a "deep" clean when I first got the gun. Lots of rough machinging marks on the hammer, sear and the rest of the assmebly.

Suggestions of polishing.

Fluff and buff with Flitz and dremel?

Switch out the fctory springs and put in a lite set of Wolffe springs and try that before you try anything else. This has helped all 4 of the GP100's that I own and its pretty inexpensive to. Then dry fire it a lot and you'll be surprised at how good it becomes! :D

You can use cloth dremel polishing wheels with toothpaste or a LIGHT polishing grit paste *sparingly* with no problems. Especially if you work on the sides of the hammer and the places where it would rub. But for God's sake go easy, and if you're not SURE you're not hurting anything, stop!

I personally would do that first, as it won't cost anything and if done right, ignition reliability actually goes UP because the hammer has more freedom to fall faster. Then if that's not enough, lighter springs will get you even further and with the hammer less restrained by the polishing, ignition will be more likely to be OK despite the lighter springs :).

Ehhh...<scratches head>...was that understandable, or too confooosing?

There's a lot of stuff going on in the GP100 DA trigger pull.

Lots of little parts and multiple springs moving and rubbing against each other. I've got one that I worked on that I'm happy with, but it was quite a bit of work for not a huge benefit. And, there are numerous ways to screw something up...

I think on this one, if you have to ask for help that's a good sign you should leave it alone.

A reduced power hammer spring may help, but may also make ignition unreliable. If you swap out springs for reduced power springs, you should shoot it a LOT with the ammo you intend to use for self-defense to make sure you don't get unpleasantly surprised.

I'd hesitate to put in a lighter trigger return spring. The GP100 isn't noted for having a snappy trigger return even with the standard power spring,

I'll second the Wolff springs and mucho dry firing.

I think your best bet for polishing things up a very light and very flat hone, or some polishing compound on a peice of fine cloth (lightweight canvas) and then place the fine close (heck, glue it) on a peice of glass. This assures you are working with an extremely flat surface, which is easier to keep from changing any of the angles...

Just my 2 cents worth..

i can't believe no one has mentioned the mainspring strut yet. polish the lenght of the edges of the strut. it is just a stamped piece and has a rounded and a flat side...you can do this with a dremal. deburr the ends too...but be more careful...back to the stone or sheet.

Now there's a good point.. I haven't actually dug into cleaning up the action on my GP yet.. too busy shooting it ;-).

I figured I'd run a few thousand through it before bothering, that'll make any problem areas easy to identify.

I got a chance to take the GP100 out with Gumshoe4 after smoothing out the trigger. I like it!!!
