I've shot the .38+P LCR and the .357 LCR.
I used the same box of .38+P ammo in both. I then used S&B .357ammo in the .357.
If I were to buy one, I'd get the .357 and plan on carrying with .38+P ammo in it.
The extra weight of the .357 LCR [a couple ounces] was noticeable in the amount of motion I felt in my hand. The perceived recoil in .38+P was less in the .357mag version.
The .38+P frame was way too lively for me. I'd trade a few ounces for that trigger and easier control.
I know- shoot it more until I get the hang of it.
Good plan. Yet, my dozens of other flame shooters would be jealous of the LCR taking all of my time.
I actually might buy this- if it gets onto California's approved list. I don't have a barrel shorter than 3", and I like the trigger.
I just wasn't going to buy one without a thumb-cockable hammer. This LCRx fixes that objection. Glad I waited.
