Happy one day early birthday to me

[Russ McDonald]

Happy birthday! A GP100 in 4" is one of my more recent acquisitions and its my primary carry gun.

It will take you 20 minutes and $5 to swap out the main spring for a Wolff and polish the hammer strut and the gun will get lot more fun to shoot. 

Does that change the trigger pull weight or just smoother?  I changed out the hammer and trigger on my AR so I am feeling confident in changing simple things

Thanks all for the birth day wishes.    I always think of the forum as my extended family.

Happy belated birthday, Russ. Sounds like you had a few good days of celebrating.

Happy birthday! A GP100 in 4" is one of my more recent acquisitions and its my primary carry gun.

It will take you 20 minutes and $5 to swap out the main spring for a Wolff and polish the hammer strut and the gun will get lot more fun to shoot.

The new main spring by Wolff makes the trigger pull lighter. I believe its 12 or 14lbs and I put in a 9 or 10lb (don't remember). Go with the 10lb. Polishing the hammer strut makes the trigger pull smoother. Ruger revolvers, specially the double action type, have a more pronounced "clunk" to them than  a S&W when the cylinder locks up. If you bought it new and not used, load up some snap caps and click off about 300-400 dry fires and it will also help smooth up everything.

If you can change the trigger in a sport utility rifle you can do this in a GP100. I just threw in the  lighter hammer spring and DID NOT mess with the trigger return spring. That's a little more work and some say its not a good idea.

The process was easy enough for me and my spastic fingers. There are myriad videos on YouTube walking you through. The most challenging aspect is simply to keep the hammer strut pointed in the same direction when you reinsert it. Look at the photo below. The side of the tip of the strut that the spring is on is more rounded than the other side. Keep that side pointed towards the muzzle. pay attention to it when you pull it out. I'm pretty sure it will only go back in one way. Simply slip off the spring over the top of the strut and plop the new one down in its place after you polish off the edges of the tip a little bit.

One will cost you $4.29 and three will cost you $8.99. I also have a  couple of delicious 3" SP101's as CCW for wife and a safe queen and since the GP100 & SP101 use the same hammer spring I bought a three pack.

Take it to the range afterward and pop off a box of rounds before taking it on an important hunt to make sure everything was done right.
