SP-101 Upgrades

[Joker18]

Anyone else upgrade their SP-101 w/ Wolff gunsprings and/or grips?
I am pretty sure this has been covered previously at some point in time.
My stock 101 had a very small stock front sight blade and was shooting very high at both close and medium range targets. I called Ruger and Ruger sent me the tallest front blade for the 101 and it put my POA and POI together.
I also replaced the stock grip with a Hogue and replaced the hammer spring with a 10# Wolff spring. The factory DA trigger pull was 14#.
Now the DA trigger pull is 9.5 to 10 # with no light primer strikes. It is a great revolver, very hardy.

I do the IBOK on all my SP101's (Iowagen book of knowledge) … google is your friend.

I do like the Hogue grips, Wood or Rubber.

I have "worked on" all of my SPs, GPs, Redhawks and Super Redhawks. Fine tuning the trigger and hammer assembly makes them shoot so much smoother. Rugers are awesome revolvers, but a little "tune up" does wonders for them.

Same here (as in SteveSt). Never a regret on the SP's or GP. Ruger builds them better than they need to, unlike the Charter's.

The only "upgrades" I've done for mine so far are new insert grip panels.
I might consider some new springs to smooth up the DA pull.

1988 vintage 38 Spcl. Meprolight sight, grip inserts of my own making, stock springs with smoothed and polished internals. I have wood Hogue and Pachmayr grips for it but I shoot it best with the factory grip with my inserts.

I've been using these in all of my Ruger DAs. They smooth things a lot.

New acquisition (French Railway Police SP101 in .38special, issued in 2000 then re-imported back to the U.S.A.), a few weeks ago after a silly colorado infringement waiting period... started out like this.

Cleaned it then took it out for a test drive, it seems to be calibrated for 125gr boolits & is very accurate, plus the Trausch stocks make it a joy to shoot.

I can't leave good enough alone... while cleaning it at home I decided to:

• Install an XS Big Dot front sight
• Clean/polished the internals
• Radiused the trigger as it had sharper edges, now it feels like my S&W
• Since then I've also installed Wolff springs and trigger/hammer shims

FYI the DeSantis Flex-Tuk for the 3" Kimber fits this perfectly as it has the same barrel shroud profile!

I like mine pretty

much stock but I did add hogue grips to a couple.

Cleaned & polished internals, Wolff springs.

Springs, shims, a bit of smoothie on the trigger. Hogue nylon grips complete my favorite.

Just bought a new SP101 4" in 327. Grips were a little small for me. Found some on Amazon I liked. I use the spring and shim kit from Mcarbo. Comes with .001 and .005 shims. This new SP trigger already has shims from the factory. The kit got it down to 3-1/2 LB single action. Double I don't know my gauge only goes to 8 LB. But its much improved. I usually put spring kits in all my revolvers. Didn't feel like polishing it yet , do that another day. Not bad the way it is.

You've got a real beauty. Great looking grips too. Congrats & hope you enjoy it.

Greetings, Gentlemen,
Very early SP-101 in .38 Special. Extremely smooth action, all it needed was Uncle Mikes rubber grips to handle 170 grain Keith bullets at 1270 fps. And red insert in front sight.
