I have 4 sets of them, 3 on J frames, the 4th on a Model 66 with the 2.5 inch barrel. I became a CCW instructor in 1996 and assure you there is nothing faster for self defense use. Lasers are only for use at night and in low light situations, which is when you cannot see the sights anyway. They also replace night sites.
The push bottom activation on the grip lets you quickly shoot from the hip or anywhere the gun might be, without even raising the gun. The bullet goes where the dot is.
The last 2 sets I bought from CDNN for $79, a bargain. I have had one set for close to a decade and never changed the battery once. I own other CT products on semi autos and never had a single problem and never had a battery fail. When your battery starts getting weak you notice it and simply replace them but it is years before it is needed.
Lasers are also about the greatest training device there is, the student watches the wobble factor and learn to control the gun and they know when they throw shots. It also solves all of those eye issues like astigmatism.
They also create a situation in which a non gun person can simply pick up a gun and have a good chance of defending themselves. When we hike I always throw in a second gun, a J Frame with a laser, any one in the group could use it if an emergency occurred or if someone was injured and had to stay on the trail while others went for help. Once a group of bad guys attempted no good,
we were the only car in a stranded and dark tourist parking lot. A car blocked us in and guys got out and approached in darkness. I handed the spare to my BIL while I gripped my own and the likely robbers left quickly when they saw it. Later we learned that people were robbed in that exact spot on 2 other occasions. Nothing better than a spare J frame with a laser as a second.
I carried a J frame in law enforcement both as a primary gun and a back up and now as a retiree I simply do not see a reason not to use them on CCW wheel guns. So your question on should you put them on a J Frame is different for me, my question is why would you not?
I have them on two models 637, a model 60 three inch and the model 66 two and a half inch. These guns are often used with snake shot as the first round or two depending on when snakes and I are out at the same time. The 357s are also carried when I hunt and walk out of the woods after dark, we have cougars where I hunt and I once was only about 40 feet from one, so I walk out in the darkness with the gun in one hand a light in the other, the laser is simply the fastest way to deal with any issue in the dark.
Hope that helps. And CDNN is a great company, bought lots of products including guns from them over 40 years. This is their current add. I just put a set on one this last week. Well worth the money to me and a no brainer. They are not pretty but they work. Hope this helps.
