RMR on target pistols

I use one on my 38sp 1911 purely because it's the lightest reliable red dot I can find. If you let the gun 'wander' it can be very hard to pick up the dot again as you don't have the tube aperture helping you align it. Other than weight I feel it has nothing to offer and is even or worse in every other respect.  YMMV.

I put one on my 45 to save weight. Spent a couple weeks raising the pistol to find the dot. Took it off and put the Matchdot back on without firing a shot.

YMMV.

They’re accurate enough.  If you have to hunt for the dot you’re moving your wrist to align the dot to your eye.  That is a grip issue.  Your hand is in the wrong place on the gun.  From a 45 deg low ready you should be able to lift the gun and the dot should be visible.  If you have to move your wrist adjust your grip so it does line up.

It just occurred to me, that was when I was still shooting weak hand, cross dominant eye.

In the immortal words of Emily Litella ...

"Never Mind"

Agreed on all points. The issue is that if you lose alignment, really only an issue in RF, then they are a total pain. 

This was, funnily enough, the first indication that I needed to go to ortho grips - my right hand can no longer adequately hold the 'fore and aft' grip for a whole 2700. I can get through the 22 just fine - with 850 ish scores. The CF starts OK but tails off really fast.  Moved to Dick's ortho grips and the 22 scores stay the same but the CF scores immediately added 40 points - all in sustained fire.  So I swapped the CF grips to the 45, worked up a reduced load for the short line and, in practice anyway, seem to have replicated the result. Conclusion - getting old sucks - especially when you've spent far too many of your earlier decades doing stupid testosterone fueled stuff that you end up paying for.
