Brilliant question on a hobbyist gun forum.
What is this thing "need" you speak of?!
I need food, a little sleep, fun time with my kids. That's pretty much what I need. The rest is LIFE, and LIVING. Try it...ya might like it.
Just my opinion, it's an impractical waste of money, at least it's not my money.
Of course, I'm thinking of getting a Glock 21 just so I can convert it to a 460 Rowland, and I already bought a Glock 20SF to convert to a 9x25mm Dillon, I'm just waiting for the barrel for the last 6 month's.
