Changing out MIM parts on S&W 15-8?

I spoke with Apex directly, and they tell me the L-frame hammer also fits the K-frame.

That's interesting, but it would have to be in one of the later revolvers with a frame mounted firing pin. I know that pre-MIM S&W hammers are different between K and L (and for that matter, N) frames because the distance from the stud hole that the hammer revolves on, to the location of the hammer nose/firing pin is different on all three. I am under the impression that later MIM hammers are also different. Triggers are the same.
 
Neal and Jinks show patent office registration, Jan. 12, 1926, for the coloring of the hammer and trigger, and renewal Feb. 10, 1948. I saw something to the effect that keeping that trademark in use is the reason for the (rather ugly) mottled coloring S&W uses for their MIM parts. In order to remain in effect, a TM must be both used and defended.

As to the idea that the hammers for the L frame and the K frame are the same, that is simply not true. The Apex person might have meant the triggers, which are the same, but the hammers are definitely not.

Factory K- and L-frame hammers may not be interchangeable, but the aftermarket Apex K/L hammer will fit both K- and L-framed revolvers with frame-mounted firing pins.

The "Apex person" wasn't confused - we were speaking directly and clearly about their hammer, not a trigger (they don't even sell a trigger). I have an Apex hammer in my L-frame, and I know of others who have one in a k-frame. If you want to know how it can be, I suggest giving Apex (Randy Lee) a call.

At any rate, it's a moot point, as the OP's not interested in an Apex hammer.
 
If that's true, it's interesting.
Can't see how they'd do it.

Are his hammers meant for carry guns?
Last time I talked to him about using one of his Smith hammers I was told they were for competition guns only, not recommended for a carry or field gun.

Yeah, I'd have to open up and closely compare a k-frame and an L-frame and the hammer to see how it's done, which is why I suggested Randy Lee might have a simpler answer. ;)

Randy Lee & Apex do a lot of business with competition shooters, so my guess is their customers normally buy the hammer and other goodies with that in mind, and that Apex is just playing it safe. If you don't spring the gun too lightly, I can't see why it wouldn't be an excellent hammer for a carry gun.
 
This is pure speculation.

Apex hammers can only be used in recent production S&W center-fire revolvers that have frame mounted firing pins. The distance from the pivot point to the face on the hammer that strikes the firing pin is slightly higher in an L-frame then the K.

But if the flat on the hammer face was extended far enough it could hit either firing pin depending on which size frame it was mounted in. But his does not take into consideration the cut-out to accommodate the hammer block.

So we will have to wait and see what the gentleman at Apex has to say.
 
What the gentleman at Apex has to say AGAIN, being that he has already told Mr Borland?

I think I (or maybe we) know what he's going to say, but I'm interested to see how they do it, considering the difference between the respective frames. :confused:
