How will a thumb rest change the recoil spring

[bill87123]

Fixing to add a thumb rest to my Caspian open gun and wondering how it will effect the recoil spring? Almost seems as if you may have to go down in spring weight to keep the slide from dipping the muzzle as it closes.

I guess it depends on how hard you press down on the thumb rest and running to light of a spring could affect reliability. When I used a thumb rest on my open pistol I used more to find my perfect weak hand grip easier, not really for recoil control.

running an 8# spring in mine and it made no difference with or without the rest. A thumb rest is just that, a rest. It's not really for pushing on too much.

[Shadyscott999]

You don't really want to push on the rest.

does the thumb rest help from pushing against the slide?

Sandman,

Depending on the thumbrest being used, It definately can help from touching against the slide. But like the others have said, may be the first thing is to focus on your grip. See what will work for you that keeps that site picture from coming off the target when you squeeze the trigger. The recoil spring would be something to address later on if it became an issue . Play around with your grip, and find out what feels the best for you, than go from there.

My addition of the thumb rest was to give a consistent position on the gun to place the thumb. The GasPedal I have shields the thumb from the slide so you can't push against the slide.

You should not push against the thumb rest as this will cause you to steer the gun in recoil.

I have a very small thumb rest on my limited, which I use more for a perfect grip reference.

Your go-no-lower weight for recoil spring should be set for reliability shooting weak-hand-only. The thumb rest doesn't change that factor at all, you can't use it w/weak hand shooting.

I use the same weight spring with the GasPedal. I use it for thumb/grip location only not to control recoil.

No change in recoil spring necessary, which is nice because you won't have to change it again when you decide to throw it in the scrap pile.

I ran them for a couple of years, and made M and GM shortly after taking them off. The more consistent tracking of the gun was obvious after just a few hundred rounds without the rest.

I am with you on this... I think. still undecided but leaning toward no thumb rest.

I have a thumb rest on my primary open gun and use it for the sole purpose of getting the same grip every time. My backup gun does not have one yet (unable to find one the same as that on the primary gun), but will put one on soon.

Using the same loads requires the same recoil springs.

Once you get used to a thumb rest, its tough to do without.

Sorry its been so long since I got back in here. Got the thumb rest on and as mentioned there was no need to change the recoil spring. The gun returned to position and stayed flat just as before. I have only shot the gun a couple of times but so far I am really liking the way it feels.
