Smith and wesson 1006 10mm

Sebego - nice bunch of them! i was hoping with my 1006 that i could use it in an up coming match "like" a model 52 . it has not a had any accuracy work done. using a bunch of different ammo the groups were huge. my sig hammerli shot 1/2' at 25 yards. my 65 4" 2.5 inches. 1006 was bigger than my model 13 3". by quite a bit 10"-15" at 25 yards.

Accuracy with the 3rd Gen guns depends a lot on how well or how poorly the factory armorer's barrel-fitment was. Initially, my model 1006 was only so-so. Not horrible but not great.

Back then my go-to 'smith had a lot of experience with S&W 2nd and 3rd Gen guns, and some of those were cop guns. He diagnosed the mediocre accuracy as being from poor barrel fitment and even showed me - by way of his caliper measurements - where the issues were, like how the hood had been relieved too much, thereby causing too much slop.

Right away I ordered an unfitted 5" factory barrel from S&W (for 1006/1026 models). You could still get them at the time and I even remember the S&W parts guy telling me over the phone: "You know a gunsmith is going to have to fit this, right? It's not a drop-in part."

Well, my 'smith fitted the new factory tube perfectly and accuracy across a range of factory ammo improved noticeably. Later, I ordered an unfitted/oversized Bar-Sto match-grade 10mm barrel and he fitted that perfectly too. I wanted the Bar-Sto for the IDPA/"Practical Pistol" matches around here and so I could avoid running up a high round-count on the factory barrel.

Proper barrel fitment seems to have been a perpetual issue with S&W's 1st, 2nd, and 3rd gen pistols. I think the 1st and 2nd gen pistols with the removable barrel bushing were likely the worst offenders. Sloppy fit of the bottom lug to the slide lock pin and the top lugs to the slide coupled with overly generous clearance within the barrel bushing and a very loose fit between the bushing and the slide was a recipe for mediocre accuracy. The fixed barrel bushing of the Models 469/669, 645, and all 3rd gen pistols helped a lot, but I don't know if barrels and slides ever evolved to being CNC milled.

Good points.

And there was a difference, clearly, between 10XX-series guns built on the "assembly line" and those built by the S&W Custom Shop/ProShop, or whatever it was called back then.

I read somewhere that the final batch of "FBI" 1076s sent back to the Bureau after the Recall were assembled by the CS/PS.
