Finally got a hold of a couple of Denali slides.
Comparison of the Denali slide vs a Davis P380/Cobra CA380 slide. The squared off edges of the Denali slide gives an allusion that it's bigger than the Davis P380/Cobra CA380 slide, but if it is bigger, it's not by much. I haven't had a chance to put the two on a scale, but they feel about the same weight.
Will the Denali slide fit onto a Davis P380/Cobra CA380? You betcha! It seems to function perfectly fine.
Here's a look at a Davis slide on the Denali frame.
I'm going to have some fun in the coming months!
