I conceal carry revolvers daily. I also have several to include a couple 4 Inch 686's.
I prefer to carry in a Pancake at 3:30 - 4:00 O'Clock on the belt. This positions the muzzle over the top of my Right Back Pocket. A 3 Inch barrel is right at the top of my pocket. I can still access my back pocket where I carry my billfold, but just barely.
So I consider 3 Inch to be my maximum year round concealed carry barrel length.
WINTER: Also consider that you may end up in a situation where you need to come out of a heavy long cover garment. The longer barrel is a problem in this situation unless you come prepaired with a long wind breaker or similar long garment that you can keep on.
Lots of spot on observations above. The Steel J's like the 60, 640, and 649 are good choices, as are the Ruger SP101's. I have owned 49's, and 649's over the years. I have both a 2.25, and a 3-1/16 Inch SP101 at the moment.
Then we have the next step up the K Frames, and the Six Series Rugers. I have several K Snubs. I have a 2" Model 10, a 2 Inch Model 15 Combat Masterpiece, a 315 Night Guard, and a 3 Inch 66-2. I have no problem carrying any of them.
The 315 Night Guard should have been the Ultimate Lady Smith. Light Enough to carry, and Big Enough to shoot well.
Next up we have the L Frame Size revolvers. The 3 Inch 6 Shot 686-4 has been my Grail Revolver since I found a reasonably priced 3 Inch 66-2 to add to the herd. I do not have a 3 Inch 686, but I do have a 3 Inch Willy Clapp GP100, as well as a RARE LE Distributor 3 Inch Bright Stainless Adjustable Sight GP100. This Baby may have replaced the 686-4 6 Shooter on my Grail List.
The 686/GP100's with a 2.5 - 3 Inch barrel are still carryable, but starting to get a little heavy on the belt. I do not find the weight to be a problem, but I read about others who think they are too heavy. A few Light Weight L Frames are to be found also such as the 386 Night Guard, probably the Ultimate Concealed Carry L Frame.
Then we have the N Frames, such as the 3 Inch 625, 3 Inch 610, 3.5 Inch 27, the Blood Works 627, and the Night Guard Revolvers such as the 310, 325, 327, 329, and 357.
I have a 310 Night Guard, which is a 2.75 Inch 10mm/40 S&W Airweight N Frame. How I would describe carrying an N Frame Night Guard would be to compair it to a 2 - 2.5 Inch Steel K Frame. With the reduction in weight it just seems like the Revolver is a couple sizes smaller. The 357 Magnum 327 Night Guard may well be the Top Dog in an N Frame Concealed Carry Revolver.
SHIELDS UP, Prepair for Rock Bombardment
If I were advising a friend on what revolver I would recommended for concealed carry in a holster on the belt. It would be an SP101, based on Value, Features, and Shootability.
The SP101 has a
pinned on Black Front Sight. The Black Sight is hard to see combat shooting, However the Pinned On Part means you can change the sight easily.
I would recommend a change of Front Sight to either a Gemini Little Wonder Fiber Optic or a 24/7 Tritium for after dark carry. Red or Green Fiber Optic ?? Good Question. I have a Red on my 2.25, and the Green on my 3 Inch. No Wrong Answer.
The SP101 can really be helped with a Trigger Job. A little stoning, and buffing, plus a Wolff Spring Kit and a Shim Set.
I have done several GP100 & SP101 trigger jobs. I prefer to work on a Ruger SP101 over a S&W J Frame.
And last an Altamont Letts style Grip Set with Fish Scale Fancy Inserts, and the Fancy Rubber grip body. The Grips are purely for looks, not much of a functional upgrade. The grips change the SP101 from being another SP101, TO
"What Do We Have Here".
The SP101 is a 5 Shot. We all know this. What most are not aware of is the F Model Jet Loader Speed Loader.
The picture is of a F Model Jet Loader in a Kydex belt carrier. Also shown is an HKS Model 36 speed loader.
The F Model Jet Loader is a Concealed Carryable size Competion Grade Speed Loader. It is a best kept secret that everyone who carrys an SP101 should know about.
