K frame 10oz Lug Terminology?

[TriTone]

Howdy,

I was looking into some Bianchi holsters and their firearm drop-down list has me a bit befuddled. Screenshot attached.

My initial reaction was that the (medium) reference was redundant, since the K is a medium frame. But, perhaps they are referring to a ‘medium lug’ here, based on the 10oz listing?

Either way, I searched our forum and ran a google search for “K frame 10oz lug” and all I got were other holster listings.

Could someone with greater knowledge, help me out, here?

Does anyone know the difference they are listing between a K frame, K frame (medium), and a K frame with a 10oz Lug?

I don't know. I would call them and talk to a human being.

Makes no sense. Some K-frames have a full underlug but the 19 is not among them. Though the 14, 16, 17, 617, 648, etc., have been made with a full lug.

For all the years I've been shooting revolvers, I've never heard of the extractor rod shroud being referred to as a "partial underlug", until the L frames came out. As you know, they have a full underlug, and not only do those go to the end of the barrel, they are shaped differently than an extractor shroud, being round instead of tapered. Maybe it's called an "underlug" on L-frame guns, or some of the newest K and N frames, but guns like the M19, M66, M27, M57, M29, M25, M26, M520, and a few others, have extractor rod shrouds, which are never the full length of the barrel.

Unless your gun has a full length underlug(aftermarket or factory) I would not choose that option.

 

[TriTone]

Thank you, gentleman. Sounds like we’re probably not missing anything, here, and maybe they are all, in fact, the same thing, labeled multiple ways.

I’ll give them a call, as J-Bar suggested, when I have a chance, and we’ll see if they can shed any light on it, lol.

Unfortunately, I think the old nomenclature of shrouded and unshrouded ejectors gets lost in the later generations of folks who learn everything from manufacturer's websites. Ruger calls them partial of "half lug". Which I think is dumb but somehow it stuck.

I suppose part of the "problem" (not really a problem) is that different manufacturers use different nomenclature for a lot of their gun parts. S&W does use the term "full underlug", but theirs is distinct from the extractor shroud on mostly older style revolvers. They say "yoke" instead of "crane", "stocks" instead of "grips", etc. Being the old fart that I am, I tend to cling to the older terminology.

If y’all think gun terms are kinda cloudy from maker to maker, you should try car parts. For example, what most people would call a “radiator support” can be a radiator support, a core support, a carrier, a bulkhead, a front end, a cooler housing, and probably a few more things.

Not only do the younger generations of buyers/owners have their way of identifying parts of virtually anything, but the manufacturers are experiencing older employees being replaced with younger people.

Then, there's the usual cross-pollination of people moving back and forth among gun companies. Older knowledge (including some terms and terminology) are aging out and walking out the company doors in retirement (or dying) ... and people coming over from another company may be bringing terms and terminology that's become familiar to them, with them, to the new company. Changes may start occurring among a company as some traditional terms may be replaced by newer terms, or terms more easily recognized, etc.

I remember first hearing the term 'barrel lug' and "under lug' being used to describe how an ejector rod was covered, and wondering why fully-shrouded and partly-shrouded ejectors (and unshrouded, for that matter) were terms that were no longer good enough to use.

Then, when I went through a S&W revolver armorer class, I had to start keep straight that there was an ejector rod that screwed onto the extractor.

Words help make sense of things, but that doesn't necessarily mean the words, themselves, have to make sense.

All those sound like PPC revolvers with heavy barrels, ribs and add-on underlugs.

 

[cfullgraf]

When did S&W make guns with 1" length barrels?

 

[Jim Watson]

I kinda sorta suspect it means 1" DIAMETER barrels.
Not factory but a common modification for PPC shooting.

I wonder if they're talking about PPC type revolvers. I've never seen a Model 19 with a 1" length barrel, but I have see (pictures) of them with a heavy bull barrel, probably about an inch in diameter. I've also seen them with big full length slab side barrels. Pretty common back in the day when PPC was a big thing. Those cats liked a heavy barrel, and the K-frame Smith and Wesson of most any variety was the most common starting point. That's how we ended up with things like "Smython's, Smolts (Smith and Wesson with a Python barrel) and Cougars (Ruger Security-Six with a Python barrel). I have always believed the "Smolts" and such influenced revolver design from the factories and gave us 5/686's and the GP 100's with full length underlug barrels.

Shudda read all the way to the bottom. That's what happens when you wake up and start posting....
