For Ruger revolver guys...

[A.J. Holst]

...I used to hang out at the Ruger Forum and met Gary Bunker [Iowegan] a retired gunsmith with an affinity for Ruger revolvers. Gary had published a copyrighted, now-out-print guide to "provide a person with average mechanical skills a means to inspect in perform routine maintenance on Ruger double action revolvers"

Being such a person, I wanted to tune up my SP101, which included successful dis and reassembly of the all the trigger parts pieces and springs.

The guide also has an advanced section if you or know somebody with the tools.

I recently spoke to Gary and have permission to share some of the information in:

Iowegan's Gun Guide for Ruger GP-100 and Super Redhawk with supplements for SP101, Security - Six and Redhawk.

For general questions and recommended tolerances, post here, for specific / detailed information shoot me a PM.

I got as many of the Iboks as I could back in the day.  That man was a wealth of knowledge.

I had one of these Iboks downloaded at one time, reasonably helpful.  The biggest deal with Ruger DA revolvers is hammer spring and friction points.  The Ruger action is an interesting design and a total departure from the Colt, S&W and Dan Wesson actions. I think anyone with reasonable mechanical ability can probably safely completely disassemble a Ruger DA revolver and do a helpful fluff and buff. In lieu of the IBok:

I sold mine. Kinda wished I hadn't.
I REALLY wanted to get the package Bowen offers for it.

They are awesome little pistols.
