I just returned from sighting in my new Crimson Trace grips mounted on my Model 60-14 (357 Magnum, 2 1/8-inch barrel). Wow! I expected them to be good, but had no idea how easy they would be to adjust to. It took a few shots to dial in the aim point of the laser, but then they were rock solid and incredibly comfortable, even with full-house 357 Magnum loads of my own creation. I shot half a dozen different loads and bullet weights and at the 5 and 7 yard distances, it made no difference. I've attached a target showing 10 rounds at 7 yards. Each set of 5 shots was shot rapidly, between 4 and 5 seconds for the full cylinder. Perhaps the biggest suprise was how comfortable they were with the 357 Magnum loads. They were on par with the Hogue rubber grips. These have found a permanent home on this firearm!
I've had a similar experience sighting both a 66 2 1/2" and a 629 5". I'm using the Crimson Trace 207's on both. The more solid grip material of the 207 takes a bit of getting used to, especially on the 629, but they're just right on the 66.
They are just the ticket for home defense, especially with poor lighting conditions..... Hope you enjoy yours!!
Now you can load some practice ammo and experiment. Check the CT video for some examples. And by the way, for cleaning they recommend removing the grips. What works for me is a piece of painters tape to protect the laser. Easy to apply and remove.
