So, I've got a '66 on backorder and am looking at bits to slick it up.

How do the SliX and the Pioneer lifter/lever springs compare? How effective is the Pioneer Coil Mainspring? Or should I first try whittling down the factory springs?

Any other tricks to buy?

Tricks?  Don't need no tricks.  Just a screwdriver.

First, a DISCLAMER:  AS a retired Gunplumber, I completely disagree with running screws "loose."  Either do the job right, or don't do it at all.

I personally think the Slix lever side springs are just fine.  A little fitting but simple.  I don't personally care for the Pioneer lever side springs.  The Pioneer Coil Main conversion works quite well.  You will need to fit the Butt Stock to clearance though.

Now you have to decide just what you want.  Do you want a Top Tier competition rifle or just tweaked a bit??  Like in auto racing, SPEED costs MONEY.  In some cases, lots of money.  there is also no real "one stop" shop.  You will need to shop around and prepare yourself for a hefty Credit Card bill.

If you are conversant with "Spring Grinding 101" whittling down the OEM springs can work quite well.  If you're not real conversant with spring grinding 101, first order up replacement lever side springs and Main Springs as you will need them somewhere along the line.  Then there is reducing the firing Pin Return Spring and perhaps an extended Firing Pin.  The ubiquitous Sort Stroke kit.  Extra light Aluminum or Titanium Carrier Block.  Lots of opportunity to clean out the Piggy Bank.  Just remember:  Gunz-r-Fun

Thank you gentlemen.

I don't plan to race this thing. I've handled a race 73 at the club once, and I really liked the super smooth cycling of it. A tricked out Marlin felt loose in comparison, although I think the Marlin is a superior design overall.

On your advice, I will first play with the factory springs and shimming, etc. Abilene, I have a copy of the 1875 Winchester catalog as well. I didn't have the best luck playing with loosening screws on my original 73, but perhaps this Uberti will work better in that regard.

Since I plan to be shooting subsonic only, I do plan to buy the carrier for the 45 Cowboy and see how I like that. That shop also had all the other bits on offer, so I was tempted to combine an order if the parts were desirable.
