I have been shooting mine a lot.
Sights: I put the Hi Viz Green Fiber Optic front sight on mine. As was said it is a hair too tall. However for Combat Practice at close range I am putting the Green Highly Visible Dot on the Target and pulling the trigger. When you are just picking up the front sight you normally have the front sight a little high anyway, so it is not a huge problem. For longer deliberate shots just hold about 1/2 the Green Dot out of the rear sight trough. For me being able to pick up the front sight out weighs the need to hold a little high for deliberate shots.

Reloading an LCR-22: The Tuff Products Model 1022 Quick Strip works fine. The Model 1022 is designed to hold 10 rounds of spare 22LR ammo in a stick. To convert it to an LCR-22 loading device just load the strip up in pairs like this: OOxOOxOOxO You need to leave a round out between pairs for cylinder clearance. Loaded in this manner you put 2 rounds in the revolver chambers at once just like with a 38, and rake them off. The Model 1022 will only hold 7 rounds loaded in pairs, but this is as good as a Quick Strip gets till the company feels the need to make a dedicated 8 shot Quick Strip for the LCR-22, S&W 43C and 317. Load 7, Index the Empty Chamber under the hammer when closing. Works fine. Also order direct from Tuff Products and get it in ORANGE. You can find the Orange ones on the ground after a practice reload. I can load 7 in my LCR-22 quicker than I can load 5 in my 442.

Speed Loaders: Speed Beez makes a dedicated 22 Speed Loader for the LCR-22. It is slick!! I got the package with 2 each Speed Loaders and a 4-Banger Loading Block. It is a little Salty however I see no way to wear it out. I rate it worth the expense. It will load up 2 ways. One you can manually place all 8 rounds in the Speed Loader one at a time like a conventionbal Speed Loader. Using the 4-Banger Loading Block. You fill up all 4 sets of holes in the Loading Block. You hold the Lower Body of the Speed Loader and push it down over the shell rims. Loaded just that quick. To reload the LCR-22 start the shell noses into the chambers and push down on the Speed Loader top knob.

Speed Loader Carrier: You have a couple choices. Modify a Safariland CD2 steel Speed loader Carrier to fit the Speed Beez loaders. OR Have a holster maker who works in Kydex make you a couple.
Holsters: I am carrying mine in a Lobo Enhanced Pancake with Optional Inner Hammer Shield. I instructed Ray to NOT Bone the Cylinder Flutes. It will also carry your LCR-38 or LCR-357. Great holster, I have 9 of Ray's holsters at the moment. The wifes dedicated LCR-22 holster is a Lobo Full Flap for retention trail riding her horse. It is a great Field Holster.

Improving the Trigger: Pick up a case of 550 Pak's and try and wear it out. The trigger should smooth out a little, and your trigger finger will be in the best shape of your life.
Ammo: Shoot some of what you carry. My LCR-22 works fine with Stingers. They are just a little stiff to eject. Velocitors lock it up on the first shot. You do not need to figure this out someday when you needed it to work. If you carry Premium Ammo in it, shoot some of it and make sure it works without issue. I have been running bricks of Federal Bulk Pak through mine. The LCR-22 loves it.
The LCR-22 is a Great Practice/Training Tool. You can shoot it till your trigger finger bleeds, and you have not hurt your budget much at all. The 22 LR works out great for Training due to the fact it does not Recoil much. You may be jerking the trigger on your 38, and not realize you are doing it. If you jerk the trigger on an LCR-22 you and everyone watching knows it. No recoil to mask you jerking the trigger. If you want to master shooting a J Frame airweight 38, the LCR-22 is the easiest and cheapest way to get it done.
You can practice Weapon Presentation, drawing from the holster.
You are working on Trigger Control, Sight Alignment, Confidence, and Building Up your Trigger Finger shooting it.
You can practice Quick Strip Reloads with the Tuff Products 22 LR Quick Strips. Reloading the LCR-22 works exactly like loading an LCR-38.
And best of all, you can get the wife to put in Trigger Time with it. You will not get most ladies to shoot many rounds through an airweight J Frame size 38. I got the wife to shoot a couple hundred rounds through the LCR-22 at one time a while back.
Whats not to love.
