If my S&W 442's a J-frame, what's my SP101?

Where does Ruger's SP101 fall in the S&W sizing? Would it equal a K-frame I guess?

Not sure if there is a definitive answer!

Just compared mine against a K and L frame - and I'd say ''K'' is about it.

Of course the five shot cyl' makes things look smaller but in actual frame size? I'll vote ''K''. ''J'' it ain't :)

Fella's;

I think it's actually the 'R' frame. :neener:

Since the SP101 eats out of J-frame speedloaders, I call it a "semi J" :D.

It's a beefed-up J.

The Ruger SP101 loads with the same 5-shot speedloaders that fit S&W J-frames, but it's heavier (about 25 oz.) and much stronger than the Smiths, being quite comfortable to shoot with nothing but full power .357 Magnum loads on a continual basis, and with no fear of breakage or going out of time.

NONE of the J-frame Smith snubbies can make the same claim. Even the all-steel Model 60s can handle only a modest amount of full power .357 Magnum, and aren't really comfortable to shoot with .357, either.

Hello. I think of it as sort of a beefed up J-frame.

Both use the same speedloader, but the SP101 seems "stouter" than the J-frame be the latter lightweight or steel.

Best.

Thanks for the good replies. Here's an important question, then. If I buy a speedloader that will feed my 442, will it also feed my sp101?

YES on the speedloaders. I have used a ruger moonclip for a sp101 in 9mm in a S&W 940 and I think it works better than the S&W ones.


In answer to the question it is a Ruger.

It is between a J and K, Kind of like a Jframe on steroids. It is what S&W should have made their 357 J frame in stoutness and leave the original J frame alone.

sp101, the j frame, and taurus small frame all use the same holsters for the most part. I would say it's like a heavy J.

In one of the S&W catalogs I recall seeing a M640-1 in .357 magnum being called a "J-Magnum" frame. The dimensions of the frame, bbl, and cylinder are different than a .38 Special J-frame.

The differences between S&W .38 Special J-frames and .357 Magnum J-frames are minimal, basically slight differences in cylinder length and diameter, or in a few cases, frame length. Holsters that fit the former will generally fit the latter, and vice versa, for a given barrel length.

"...sp101, the j frame, and taurus small frame all use the same holsters..."

Unfortunately, this is NOT true.
Many S&W J-frame holsters will fit the small frame Taurus guns like the Model 85. After all, all of Taurus' original tooling was what Bangor Punta left there in Brazil when S&W changed ownership, and their original revolver designs were close copies of the Smiths.
OTOH, holsters made for J-frames WILL NOT fit the Ruger SP101. I have half a dozen J-frames and two SP101s, and all the J-frames fit in the same holsters as each other, but the SP101s won't fit in any of these. It's simply a bigger frame size.

The SP-101 is a J frame + :neener:

I know at least one that will. My SP101 rides securely and comfortably in a Kirkpatrick 4100 j frame belt holster.

A J and a half frame?

A gunsmith told me that both a colt detective and a Ruger SP101 are "D" frames. I don't know if he was pulling my leg or if that is correct.

I do know that from talking with holster makers, the same holster will always fit a colt detective (and other similiar colt revolvers like the agent) and a Ruger SP 101.

Of course, this assumes they all have basically the same barrel length.

The D frame is a Colt designation. It has nothing to do with Ruger.
The D frame and Ruger SP frame are close in size, but the SP is bigger in most dimensions except for cylinder diameter.

I was told that the SP-101 is actually stronger than the K frame Smiths...I would'nt doubt it myself....Rich

Take a caliper to any new made "j-frame" and then to an older (before the introduction of the .357 J-frame versions) J-frame. Even the .38's and .22's are built on the new slightly longer .357frame now.

it would apear that the sp101 is a "J" frame that was built to last, carried a lot and shot as often as you wished, unlike the s&w "J" frame.
it is simply a beefed up version of the J frame...
