The lightning, having a smaller, lighter frame, shouldn't be subjected to 357 pressures. I've never tried but I'm guessing you can't fit it in the cylinder as is. Curiosity may get me to check.

I answered your pm. See you there.
frog,
where are you? i have a pair she can try. my wife shot them till she pretty much wore them out and now shoots a full frame with gun fighter grips.
she can try these lightnings, my thunderers or her GF grips. send me a PM with contact info or tell me where you shoot. we live in norco and you can usually find us at west end or cajon on saturdays.
