Well, I did it. My model 336 went out to Marlin yesterday for the "Cowboy Conversion" and I am already having second thoughts, mostly because my baby is out of my reach. It will be interesting to see what I get back, if it will have the full length magazine or the shorter one like the old model 336A had.
The longer sight plane should make it easier to shoot accurately, and I hope to be able to wring a little more speed out of the bullets compared to the 20" barrel. At any rate, I asked to have the old parts returned in case I decide I really liked the original configuration better. We'll see.
