I finally bailed my new/used GP-100 out of layaway yesterday. took it home and gave it a thorough cleaning and oiling. I don't think its been fired in years, there was alot of solidified gun oil in the action. The only problem that seems to be there is that the trigger is a bit lazy, sometimes it doesn't return all the way forward. I'm thinking some dry fire practice should loosen it up and maybe solve the problem. Man, this thing is big and heavy. I don't think it would be a problem for the gun to be built as a 5 shot .41 or .44. Anyone know of a good shoulder holster rig for it?

That's a beauty. Try some solvent in the trigger group to loosen it up and flush it out. The trigger return spring might have been changed or weak. It is easy to replace the mainspring and the trigger return spring if necessary. 8) 8)

Man thats a ugly gun I`ll take if off your hands!!! because I only have 2 GP`s and I don`t think it`s enough :) Nice gun

I just got finished with 3000 dry fires [ with my GP100] and the trigger is very very good now....I have read that for whatever reason... I have no idea, some that had problems with the return of the trigger...their trigger spring was broken...I`m not saying that's your problem...but if it is it`s a simple fix with a inexpensive new spring....Holster... I`m thinking it`s a Uncle Mikes I saw that was nice and reasonably priced....Jim
 
How far "down" did ya go with it ???

I`ve smoothed up some very ruff trigger return spring wells !

& as easy as it is to change springs in someone may have installed a 8# trigger spring , which is a bit too lite in most GPs without smoothing things up .

Even after smoothin things I like the trigger return to be snappy & I consider the 10# return spring to be minimum.

But there`s other things that can cause a "lazy" return.

Looks to be an early 1 `86 or `87

Nice peice !!!

For woods bummin & huntin I like chest holsters !

GP100man......Do you remember if the GP100 factory trigger spring is a 12 lbs. I just finished dry firing [ gp100] and I have the springs and I`m going to experiment with different springs, what do you think is the best lb. mainspring is also.

SORRY FOR THE LITTLE THREAD JACK......

Nice revolver. A good cleaning, a drop of oil here and there and a bit of dry firing will fix you right up. :)

Great looking GP100. You will enjoy shooting one of the finest 357 magnums around. Like others had said dry firing a lot will improve the action. That is the beauty of a Ruger DA revolver.

Enjoy yours,
Howard
 
Thanks alot guys. Yeah, more dry firing is in store for it. The trigger fails to reset only about 1 in 30 pulls. What happens is that the trigger doesn't make the very last little click to fully reset. I did remove the trigger mechanism and clean and oil it last night. If I had to guess I would say everything is just stiff inside it from not being fired in so long.
 
I don't recommend dry firing the gun because you will wear out the action quicker. Sitting in front of the tv and pulling the trigger over and over is a waste of time. Just change out the springs and buffout the trigger action is very easy to do for this gun (look up youtube!). Here's a good post from the other Ruger forum (read Iowegan post!) http://rugerforum.net/ruger-double-action/11178-dry-firing.html
 
The latest GPs come from the factory with a 10# trigger & a 14# hammer .

Most have a 12# trigger & 14# hammer , my latest ons are a 2001 & a 2006 & they both had 12# trigger springs.

My preference is 10# trigger & 12# hammer & smooth !!!

I also concur with actionflies , a good smoothing of the parts of the GP is alot easier on the finger & revolver than dry firing 3000 times , the notches & cyl stop catch trouble in the dry firing !!!

Shimming the trigger & hammer does alot for consistentcy also !!
 
That is a very nice looking GP100! From what I can see in the photo, it sure doesn't look like it has been used much, not much of a line on the cylinder and blueing looks really good. It could be that a very light or modified trigger return spring has been installed, or just really gummed up. Removing the trigger group, and removing the trigger return spring should tell alot. At any rate, it should be a very simple and inexpensive fix, and that is one beautiful blued steel revolver. It should serve you well, and I'm sure you will be very happy with it!
 
It's not a clamshell grip. Remove the grip screw and slide it off. Just do a search in youtube.com and all your questions will be answer.
 
Dry fire away, you will never wear that action out...

I use one of my GPs for action pistol shooting, I shoot more in a season than most people do in a lifetime.
 
Thanks for the kind words. Now, I have found that the wood grip panels on this gun are bonded to the rubber somehow. I can't tell if its glue or just the rubber became tacky and stuck to it over time. The panels are seated pretty firmly though and I think I would have to carefully cut them out to remove the panels. Is this the way they are supposed to be?
 
Here's mine:

looks like a twin brother, doesn't it?

I bought it a short time ago, it was used and, in overall, good condition. It had one annoying problem though: a catch in the trigger movement. In the beginning of a trigger pull something would get stuck and require additional force that would eventually pull the trigger through and all the way, causing the gun to fire. The fact that the previous owner installed the Wolff springs made it even worse, as there was no way I could control the trigger after pushing it over "the hump".
Last week I took it to a local gunsmith, whose initial inspection confirmed that something was wrong. He kept the gun for a week, and today I picked it up. The gunsmith fixed it, and guess, what it was - the grip screw was out of alignment and the mainspring was catching on it!
He said he had never seen anything quite like it.
On my request, the gunsmith also changed the springs back to the original ones, which were thoughtfully included together with the gun by the seller.
Later this afternoon I fired a whole box of .357's through it, all double action, with no resistance above the typical GP100 trigger pull, which I, unlike some others, don't find bad at all.
I'm very happy now, it feels almost like getting a new gun!
 
I did quite a bit of dry firing last night both DA and SA. The trigger is feeling really good now and only failed to reset once or twice. In fact, I find that the DA pull on it is very easy to control and keep on target.
