Initially I didn't understand what alot of the reference numbers were about but, having taken the gun apart it now make alot more sense to me.
I think I'm going to go with the stronger/heavier cocking lever and cocking spring for starters. While I had it laid out on my bench the other day it just looks like those two modifications alone will be enough to give me a slight increase in performance without alot -no turning back- of alterations.
If these two small changes don't do enough for me then I'll seriously consider the mods listed in those instructions.
Do you happen to know what the exact size and compression strength the cocking-spring is?
I finished up my work early today so I took that extra time I had and installed the receiver mounted peep sight I mentioned in one of my other posts. Nothing fancy, just functional. I milled down the front and rear factory sights and dove-tailed the front for a "Globe Front Sight."
If I get some more free time next week I'll start on the heavier cocking lever then move on to replacing the spring. I think I've figured out an easy way to add a little more mass to the cylinder that impacts and opens the air valve; and it doesn't require any alterations.
More to come. Oh yea, I forgot to mention; my 909 is the one with the single air reservoir. I think it's the 909S.
