just buying because i want a revolver to go with the collection and target shooting . i want the smaller barrel and is the size difference is a lot ? none of the gun shops have them in stock so it is hard to get a size comparison of one being next to the other .
It's enough.
If you want the shorter barrel, I can't suggest the SP101 enough. Less grip options, though. You can only get round-butt grips from Hogue, but the rubberized one they sell is GREAT for range shooting.
Personally, I have boot grips from Badger, which are GREAT for carry (though thick, so they kind of get in the way of ejection and speed-loaders...). I think Trausch sells a more squared grip if it's a dedicated range gun, though I've never handled their products.
Long story short, both are great guns. They're strong as it gets. They're all GO, not as much SHOW (the opposite of Colts). Have a trigger job done, and you'll have a perfect revolver.
