I have a 4" SP101, and a 3" M60, both with adjustable sights. I also have a couple Black Hawks, 4 5/8" and 6" and a GP100 6". The M60 and SP are more portable, and both shoot well enough to be a threat to foxes or groundhogs out to 20-30yds, and better shots than I, much farther.. The 6" guns are more effective at 50yds, but are in the way at times. None of them are for sale.

For the shooter wanting "more portable", the 5 shooters are so close, it's a flip of the coin.
