Ooooooooo, nice Christmas present Ken. Question is though, didja treat Moma at least as good as you treated yourself, hmmmmmmmm????? Sorry, just being a bugger (LOL).
Savage has some good suggestions. I too would treat it just like any other 45. But, for loads, I am a hardball kinda guy and prefer that or a reloaded equivalent, be it cast or jacketed.
I would break the gun in as Savage suggested - I do that with all my autos - take at least 200 rounds to the range and break it in. Then, however, and because I usually stick with hardball, I stuff it with a 22 lb recoil spring kit from Wolfe. Liability statements aside, you should be able to shoot cast without any problems what so ever. My only thought is that you might pick up some lead deposits in the barrel ports if you shoot some of the softer cast bullets but if you shoot hard cast you should not have any problems at all.
My younger brother is finally giving up the ghost on his 9mm and trading it for a 45. Only problem is that he doesn't quite yet know which one he wants. He shoots little but carries a lot, so I have thought that a lightweight Commander length might be to his liking. I'm trying to orient him to Springfield but he keeps talking Kimber. So, we'll have to see what different models they may or may not sell and then select from the maker who makes what he wants. I know Springfield makes a lightweight but I don't know what they call it.
Hay, let us know how that shoots........................This be yor ol buddy the Original Mikey...
