markc: Yep, it needs a breaking in.
Your ammo could also hang you up a bit. White box is on the slow side. I would buy 500 rounds of Sellier and Bellot 230 gn ball (850'/sec, functions my 1911s with 22 lb recoil springs,is reloadable) and about 4 more magazines (get 8 rounders from Chip McCormick), a large cup of coffee and a couple of frosted thingys or a good sammich and shoot that thing, like maybe 500 times or more. It will be broken in by then, certainly.
I would start out with a clean, lightly oiled gun and shoot it until you use up your ammo - any way you want or can at your range, fast or slow, target, combat, IPSC, silhouette, whatever you want but have a couple of different types of targets to shoot at or you can get awful bored looking at one large hole in one long dead target. Of course you want to bench it for accuracy before during and after to see if the groups shift.
I would bring a cleaning rag to wipe off any excess oils that may start to creep out from nowhere after the piece starts warming up and maybe something to run a dry patch into the chamber if it starts running sluggish and it isn't your hand starting to palsy after a couple of hundred rounds........ but I wouldn't clean it until I got home or if it needed some cleaning to function (but not with new, quality ammo).
Ah yes, your wife {Well Marc ol buddy, ya see, ya depends on us now to keep tight lip about this, so maybe if ya send us yer gun an alla yor ammo we'll shoot'm up fer ya (snicker, snort) an not tell yer wife, maybe or} you could always make it a family day at the range and find out from your wife how she thinks it handles. Family oriented I iz............... Mikey.
