well as has been pointed out countless times here.
any new design weapon is basicaly going to have a few growing pains!
look at the new beretta mini 9MM, the Kimber Mini 9 MM, the Sig sauer 238, just to name i few recent introductions!
I had a stainless Colt officers model way back when thye were newly introduced and the thing never would run 100% on anything, and hollow points were terirble, this includes 2 trips back to colt and 1 to my gunsmith.
what may look perfect on the drafting table many times has "Gremlins" when produced.
