10mm Ammo Choices 4 Dummies

Now if we could take this one step further... spring selection for these different loads. 
Heavy springs for heavy loads?
Lighter springs for lighter loads?

No, a properly sprung 10mm Auto pistol will drop "FBI Lite" neatly at your feet. The "full house" loads will jump a good three feet from the ejection port.

My Kimber Eclipse throws them a LONG way ... maybe around 20 feet or so.  Doesn't seem to vary noticeably with load, springs, flat firing-pin stop, ... .  I've given up worrying about it.

Idea....shoot your guns first with all the loads before getting new springs..my g40 shoots everything like a sewing machine with stock spring.it is right now  stripped apart and being ceracoted...gonna be as good looking as it is shooting!

The reason I ask is because a Tanfoglio I'm considering comes with 3 different spring weights...

This is somewhat common in high end target pistols.  Guys may shoot really light loads for bullseye style shooting that may not cycle a gun with a "standard" weight recoil spring.

Until recently, I stayed with the stock recoil spring (18.5 lb) in my Kimber Eclipse, and it functioned fine with full-spec ammo ... Kimber just recommended changing the spring more often than the standard interval for medium-power ammo.  But I started to notice some battering, and since then I've been using the next step up (20 lb).  Still shoots the full-spec stuff fine.  I shoot only the full-spec ammo (DoubleTaps, of various weights), and so I don't know if milder rounds will cycle OK or not.
