I have shot one and I own a Model 60. The LCR is not bad and weight is always a concern when backpacking. The SP-101 is heavy.

LCR = 17.1 oz
SP 101 = 26.0 oz

I use a 329pd and it is a 6 shot 4" barreled .44 magnum and is only 25.1 ounces. If you are willing to pack the weight of the SP 101 I would get the 329 and gain 1 shot, 1 3/4 inch of barrel, and a bigger caliber. But that's just my opinion.
