I got a chance to get out for a bit today, and shoot my BUG, which is my old 442.
I have a set of old CT laser grips on it, and have always maintained that they are the single greatest aid to marksmanship that I know of for J Frames.
My eyes have changed drastically over the last few years and front sights are very fuzzy to the point that I often just "use the force" and pretend I am a Jedi.
Anyways some pictures of running what I call my Ear Nose Throat gun.
Conditions were overcast, with a slight bit of rain.
At 7 yards there was not a huge difference, but I was still more in the center, with the laser versus irons:
First group w/ laser:
Next was w/o. Then I compared.
10 yards was where the difference really was noticeable:
I need some new paint for the front sight too, the gun is fairly worn.
Unfortunately I ran out of time, as I had some rifle stuff to do before heading back, so I did not have a chance to run the J Frame at 25 yards and further.
For me, the CT laser grips are a rather significant advantage over irons if the lighting conditions are appropriate. If it is bright out, then I go straight to irons.
