Shimming?

I saw another forum user mention that he 'shimmed' his trigger and hammer to take out side play. What exactly is shimming and can an amateur do this with careful instruction OR is it better left to someone that has experience doing it? I do not feel my Blackhawk needs it but I am curious.

The basic concept is to measure your gap and add a shim or shims to center the hammer or trigger. If you check the link above there are instructions and videos on how to do it. Pretty simple process if you feel so inclined and well within the skills of a DIY'er.

This post caused me to check the lateral play in my triggers. I'm seeing about 0.020" to 0.030" amount of play in all of them. Other than that, the trigger is square and there's plenty of interaction among the parts and they work great.

What issues are you having that make you want to do this? What problem are you trying to solve?

I shimmed my SP 101 and my GP 100. In my mind it takes the sloppiness out of the moving parts and creates a smoother operating pistol.

Hammer and trigger shims are mainly intended for DA revolvers, where the two parts may drag on the sides of the frame cutouts when shooting in DA mode. I can't see where shims would really be needed on a SA revolver.

It's actually pretty easy, there are several good YouTube videos on how to. I followed the instructions and smoothed and shimmed my SP101. 22LR and added the new model spring kit.
Trigger and hammer pull much smoother and lighter!

I've shimmed several revolvers. It does improve the action but there's a slight negative when dealing with a Ruger DA revolver. Every time you remove the hammer from a Ruger DA revolver such as a GP-100, SP101 or Service-Six, you must re-install the hammer shims. It's not a huge deal but the shims used to center the hammer are held in place by the hammer pin, which must be removed if the hammer is removed from the frame. The other shims (DA sear, and trigger shims) are pretty much a one time only job.
If you disassemble your Ruger DA revolver often, the hammer shims can be a bit of a pain to re-install every time. Other than that minor annoyance, shims are a great idea.


Shameless endorsement here for: Triggershims.com - they're great company to deal with.

A trick I learned to keep the hammer shims in place as you put it in the frame is to use a light grease to stick the shims to the hammer, line them up with the pivot pin and put the hammer in the freezer awhile!
They will stay in place when you put it together! A real headache otherwise!

Good post jalopiejoe, I've used this trick for a lot of years from everything to working on farm equipment(grew up on farm), motor vehicles, heavy equipment, and of course firearms. Good link by Waveforms on the business that sells shims, glad to know of their existence, will be sending order to them. A lot of good info on the shim link, they offer a lot more than Brownells carries.

Google trigger/hammer shims for Blackhawk's and you'll find a page or two of threads dealing with this subject. I've bought a few packages of Triggershims shims and they do tighten up the action. The only RSA I have that doesn't have shims inside is one that is at Clements Custom right now.

Make sure you put them in per the directions. If you try to get the trigger too tight, it will not operate correctly, so measure and leave yourself a little room.

Does it make the revolver more accurate? Not necessarily. However it does tighten the thing up and doesn't hurt.

YMMV and all that.

Thanks! I shimmed my hammer on my SP101 WC, and it was frustrating to say the least.
