Conversion gives one the ability to test out a caliber you would not normally fool with at a low cost.
Spend about $130-ish on a Lone Wolf barrel, go get some ammo, and you are in business.
Once you have tested out the new caliber, you decide if you want to buy a platform for it.
If not, you either sell the barrel on an auction site, and order the next caliber you want to try, OR
you keep it in case you run out of 10mm ammo...always good to have options!!
Bottom line, you get to experience MORE shooting fun!!
That being said, go get an extended length 9" barrel to play with...opens up even MORE options
