Fitting wobbly stocks

[drumminor2nd]

Hey, all. I have a Model 27-3 and a pair of Jay Scott oversized trooper stocks I'm trying to put on it (the targets that came are just too big for my hands, while these fit my hands well). They go on just fine, but when attached with the screw tightened down, they rock back and forth (as in pivoting around the screw, finally bumping the backstrap or front strap and stopping). It's not a ton of movement, but I really don't want a .357 wiggling around in the grips every time I shoot it.

What is SOP for getting these to stop doing that? Just cardboard shims, wood filler, epoxy? I can't be the first person to run into this problem, and as such don't feel the need to reinvent the wheel.

Thanks!

Glass bedding, or paper shims would work too.

I’ve had good luck with plastic shims cut from water or soda bottles. Clean them well with alcohol. Aluminum from cans or paper scares me, since they might cause a reaction that could rust the front/back strap. Wood shims or vaneer are obviously the best, but I don’t typically have those on hand.

Cut a few strips the width of the backstrap about an inch long and put one of the grip panels on the gun. Rotate the panel until you have the maximum inside gap front to back and slide one or more shims into place until there’s no movement. Mark the location on the panel and glue the shim(s) into place. Go sparingly and you only want to glue it to one panel, so you can easily easily take the grips off. I use craft glue, since it’s not permanent. Give it an hour to set up and put it all together.

It’s not the way a pro would do it, but I’ve found it very effective for a shooter grade gun.

The locating dowel at the bottom sides of the grip frame should prevent the grips from doing this; "rock back and forth (as in pivoting around the screw, finally bumping the backstrap or front strap and stopping).

Or maybe the locating holes in the Scott grips are oversize. Use stock bedding to fix.

The other possibility is that the back side of one or both grips are warped. Check with a straight edge and sand them flat if needed.

Those are the two most common reasons for grips moving around.

My long time go to is 5 minute epoxy and Johnson's Paste wax or shoe polish wax.

Apply a medium-heavy coat of wax to the entire frame around where you need to tighten the fit. NOTE: NOT car wax.... that's not suitable for this purpose.
Don't wipe the wax off, let dry 20 minutes.

Apply a little 5 minute epoxy to the area needed, quickly mount the grips and align them correctly with each other and the frame.
Snug the grip screw down and allow the epoxy to cure.

Remove the grips and clean up any excess and wipe the wax off.
That's a permanent repair.

To provide long term protection from corrosion under grips, just apply a medium-heavy coat of Johnson's Paste Wax to the areas covered by the grips and allow to dry 20 minutes, then mount the grips.
The coat of wax will prevent rust from moisture and sweat.
