Have a LCR 357 with Hi-Viz fiber optic sights on it.  I love it!  Carrying it a lot because it's super comfortable to carry and I shoot it really well.  I bought the LCR 22LR the other day with the intent of using it as a trainer and getting the same sights.  Unfortunately, it turns out that the Hi-Viz FO sights don't work on the .22 and 9mm versions of the LCR and no one makes a FO sight for them.  The sight on the .22 and 9mm versions is shorter, so they hit really low, even at 7 yards.

So, I designed my own FO sight that works with 0.060" FO rods and is the same height as the factory one.  I printed it on my resin 3D printer using Resione K+ resin.  This a new resin that is supposed to be very tough and can produce functional parts.  Not sure if it lives up to that yet, but this is just a range gun so I'm not too worried.

Nice. I’ve been looking at LCRs as of lately. Hope yours shoots well.
