lighter dot

I have a walter gsp with a Champion choice mount. I have a ultra dot 2 mounted. However, after shoulder surgery, the gun is too heavy. any lighter sights for a replacement

Had similar problem. Holosun was the only lighter choice.

There are others….Sig Romeo 5, and others….

But if you really want to have a lighter dot, you need to look at reflex open emitter dots.  They’re accurate and VERY robust.  They’re a bit problematic to adjust for range changes but there are ways around that.

I have Vortex Venoms on my .22 and 1911.  They are simple, weigh very little, and have worked fine.  As others with astigmatism  my 'progressive' corrective lenses can make the dot look like the 60s, but this was mitigated with new shooting glasses that are UNprogressive (single Rx = distance).

You may also want to consider a lighter gun for awhile.  A Ruger 22/45  with a trigger job, and a lightweight red dot might save more weight and help keep you shooting.
