Paladin7,
The six slot moonclips S&W sources, like the ones Brownells, etc, source, came from Ranch Products. They are the same ones used by 25's and 625's. I don't know if they still include the two-slot 'one third' moonclips as mine, bought new 6/11, included. The thickness of the 'clips affects the headspace, ie, they are all a given thickness. The cartridges are meant to be turned or twisted as they are pushed into the slots. Removal is easiest with a 'demooning tool', and I prefer the nutdriver-style available from Brownell's, etc, for <$18. It will hold six empties in it's tube, permitting faster reloads - just have a bag/box to dump the empties in. I've found that Remington & Starline brass seems to load more easily than other brands. I reload, so I ordered 1,000 Starline .45 ACPs years ago (~$130 delivered then - not much more now - just a long wait for stock!). Revolver brass doesn't get scratched up by extractor/ejectors, so it stays nicer longer. As I said, I keep ~240 moonclips loaded, mostly ball ammo but some with 255gr LSWC as a revolver doesn't care what shape your bullets take. The last Ranch Products moonclips - blued steel - I bought were $35/100 - they are probably a bit more now. Nice folks.
I'll grant you, the Governor won't win a beauty contest. The trigger is pretty stout - apparently, #209 shotgun primers take more strike energy than LP CF primers. One range denizen summed it this way, after trying my example's stock trigger; "I didn't know S&W made a Sigma Revolver!". While it's not a target gun, it's accuracy is acceptable, as my sub 3" groups at 12yd were from a standing two hand hold - ie, not rested on/against anything. It's Tritium Night Site does not win points with me - my mature eyes find it, like my 60 Pro and 632 Pro similar sights, requires complete darkness to be seen, making it difficult to see your target. I prefer the f.o. 'HiViz' sights.
