Hi Kevin, well I should have gotten is this one:
Thanks for the tip, I just ordered one, my CP-1M arrives tomorrow...
As an aside, I do like that style knockdown target. But it always bothered me that the kill zone is a gut shot so a while back I fixed it by adding a paddle behind the brain.
I'd go with the cp1 if you can afford it. Much better, steel breech instead of plastic, magazine. No comparison really. Plus you can get the new grips and stock for $25 if you decide you want to carbine it.
