That's a kind offer! I'm in Washington state, but I appreciate it.
My friend has both .357 and 9mm LCRs and we've a range date planned.
My other issue about the 640 Pro is that I'm not sure who makes the sights. They LOOK like Novaks, but Novak doesn't list them as a catalog item. So you're stuck with the front sight it comes with and have to file it to change POI. Also when the lamps go dim, it doesn't look like I can just knock them out of the dovetails and replace them.
The big draw to the 640 Pro is the weight to soak up recoil, and the fact that all my J-frame speed loaders, grips and holsters will fit it.
The .357 LCR is only a couple ounces heaver than my Airweight 638s and I have buy new support gear. I'll have to do some a/b testing and see if the sights are worth that.
Thanks for your thoughts!
