    What models have been made with a bobbed hammer in 9mm? What are the ballistics like out of these with 147grn ammo? How would they compare to say the 158grn FBI .38 load? Can they handle 9mm +P ammo? Recoil comments?

    I only know of the Model 940, which is not a "bobbed" hammer, but a concealed hammer, aka "hammerless." It has not been produced for some time, however.

    S&W also made the 547 k frame but no bobbed hammers there either.

    As stated earlier, the 940 has a concealed hammer; it is a Centennial revolver. The hammer spur on the 547 is shorter than hammer spurs on other K frames, but it is not bobbed. I am not certain, but I think Ruger bobbed some hammers on the 9 mm Speed Sixes.

    Recoil comments:
    My M940 with regular velocity 115gr 9mm recoils
    almost exactly like my M60 with 125gr +P 38 sp.
    The 9 is more like a kick and the 38 is more of a shove.

    I am no S&W engineer, but I feel comfortable saying that they can certainly handle +P 9mm (it's only at most 10% over SAAMI specs anyway and the same revolvers do just fine with .38+P and .357) and that you can probably expect to see slightly better performance out of the 9mm than the .38 out of the little revolvers. Maybe the same, but the 9mm is higher pressured, is usually measured out of auto barrels that realistically are shorter than they get credit for, so I think you can expect a little more than you'd think out of the 9mm.

    The 940 will handle +P without a problem. The Performance Center made a run of 940s in 356TSW, same exact gun with chambers reamed a little deeper for the longer case, and it pushes pressures to somewhere around 44,000psi.

    I have a 940. It came with the Micheal's Boot Grip, tiny. Its' recoil is like catching a baseball from a major league pitcher without a mitt. Ouch! (and I have shot 45-70 Thompson Centers without too much of a problem)

    The 940 was the only J-Frame Smith 9mm made. It is a concealed hammer model, like the 640.

    Smith did make an N-frame 9mm, as somebody mentioned, the 547. It came in 3 and 4" barrel lengths and was primarily sold overseas. It had to have a protrusion above the firing pin to keep 9mm cases from rebounding in the cylinder. You could bob the hammer on those, if you can find one.

    The Doc is out now. :cool:

    My BUG is a custom 9mm S&W 360J, it has a scandium frame and weighs just over 13oz. I've found the recoil with standard pressure and +P 9mm comparable to the equivelant .38spl.

    The S&W M547 is actually a K-frame M13 chambered for 9mm with a special extractor so it doesn't use moon clips. I've never heard of any factory N-frame 9mm, although your could have a M27/28/627's cylinder modified to shoot 9mm with moon clips.

    The protrusion in the 547 is actually a retaining pin that strikes the cartridge case at approximately the same time the firing pin strikes the primer. I say approximately as we are talking miliseconds. The 9 x 19 case is tapered and tends to back out of the chamber when fired, so the retaining pin keeps the case in the chamber. If you look at the head of cases fired in a 547, you will observe the retaining pin mark on the case head.

    Like many others, I would like to see S&W re-introduce the 547 and in a stainless steel version as well. However this is not likely to happen.

    I kind of figured 9mm would be really felt in J frame. I toyed with the idea of having my model 63 converted to 9mm. But nothing is cheaper than .22LR for plinking

    supposedly, 9mm suffers less balistic penalties from uber short barrels than does 38 and 357.
