For years I have been looking for a grip that is small enough for pocket carry, fits my hand nicely, absorbs recoil and isn't "sticky". I finally found it. Plus it looks cool on my 642.

Diamondback SDR and the Recoil Rider grips are the CHEFS KISS!!!!
...and No i am not being paid or being given any merch from anyone. Here is my humble review of both these items in the hopes that you out there reading who might be curious can make a better informed decision...The SDR has been flawless. Its the glass bead finish 2 inch barrel model. I have a total of about 500 rounds and after todays range session I consider it broken in and ready for Fall EDC. I ran over 150 rounds with a 50/50 mix of 38 special plus P and 357 mag. This was never possible before because the beautiful cherry Altamont grips were downright painful after a wheel or 2. Single Action and Double action were a joy and the fiber optic sights stayed in place! The softest 357 mag ammo I ran was Winchester Train and Defend 110 grain SJHP. Felt good and not like a sledgehammer. The Recoil Rider grips are everything that I have read on the Reddit forum and the website did a good job of describing them. They never got sticky like my rubber grips. They DID SOAK UP the recoil as was mentioned. I went with the standard size so my guess is the larger ones would be even better for recoil control but I don't feel it necessary to upgrade since the regular sized ones are good to go. If you can get over the price then make the jump and dont look back! Its nice to know we have another option now for us Revolver Aficionados!

The Standard Fit J- Frame Grips are a very good upgrade over the OEM S&W stocks. These grips are easy to install, fit well, and are very comfortable. I also believe they provide better recoil shock absorption along with being lighter in weight - approximately .8 oz lighter. Overall, I am very satisfied with these grips, and I recommend them for the S&W J Frame revolver.

Took my UC 632 with the Boot Grips to the range yesterday. A buddy and I put a full box of Lost River Ammunition's .32 H&R Magnum 100 gr Polycoat Full Wadcutters through it, and it was great. The grips aided in natural pointing, and reduced the felt recoil to almost nothing. They are very concealable as well.
My buddy and I are both retired law enforcement firearms instructors, and would highly recommend Recoil Rider grips for any of your revolvers.

Love these grips! I compared them to the Hamre Forge grips I currently own and the Recoil Rider grips were superior in comfort and recoil management and equal in concealment. The switch to Recoil Rider grips was a no brainer for me. Now I’m thinking of trying them for my Ruger LCR.

This is the third grip i have tried to tame the j-frame (638). My hand exceeded the dimensions listed on the site so i ordered the bigger grip and it is very nice. I don't have to shove my trigger finger halfway into the guard anymore. For the first time i took this to the range and shot 100 rounds of 158 grain 38 spl and it was a pleasant experience. I used to shoot 25 and move on to something else due to the discomfort of shooting. All this and I can still pocket it without dressing like a tactical Hobo.

Smaller than the factory grip. Made the perfect fit I was looking for in the way I carry.

Instantly changes the feel of the Ruger LCR. Makes for easier grip allowing 3 fingers to be on grip. Grip also does away with the snag factor that the original hogue grip has,since I carry it aiwb. Shot with 38 and 357 mag grip does well with the recoil of both. The grip at the trigger guard also eliminates the "Glock knuckle" factor that the hogue grip had for me! Highly recommend this grip,don't think you will be disappointed.

Bought a set of these grips for my Ruger LCR and they are perfect. They hold much better than the stock grips and don’t grab at clothing at all. Their footprint is also smaller (but just the right size) than every other option I looked at on the market. You won’t be disappointed!

Absolutely completely changed feel and performance of my Smith and Wesson p 360d. Tamed this beast, pleasure shooting 357 now

I recently purchased a Smith & Wesson MP340 and found the stock grip to be too small for my hands, making it hard to control the weapon. After doing some research online, I decided to purchase a set of large Recoil Rider grips. The difference is is phenomenal in controllability of the weapon,accuracy and reduction of recoil.

THANKS FOR THE FAST SHIP. THE GRIPS ARE GREAT, GLAD I ORDERED THE LARGE SIZE, THEY HANDLE THE RECOIL QUITE WELL.

Excellent.Reduced perceived recoil. More natural angle for wrist. Better trigger reach distance. Definitely worth the upgrade.

After a million revolver grips that all do the same thing because "that's the way it's always been done," someone is finally trying something different. These grips combine three things that you normally don't see on the same grip: 1) a covered backstrap to cushion the hand and put the trigger finger on the trigger where it should be, on the first crease; 2) greater clearance behind the triggerguard, allowing you to get a higher, three finger grip in the same size as a normal two-finger grip; and 3) a radically straighter grip angle, making the gun point more naturally for more people.

I loved the result. Better pointing, an easier trigger pull, and better recoil control.

The only points of improvement I could suggest would be more traction, especially on the backstrap, and I wish the pinky ledge was more vertical, to give it even more leverage. But those are quibbles. A great design overall.

After installing and using the Recoil Rider grips for both LCR and Taurus 856 revolvers, I sincerely recommend them. For the LCR, I've tried all the Hogue grips, with none being satisfactory for me (either too small, too large, or too "clingy" against fabric), the Recoil Rider - size Large for my average-sized hands - is a perfect compromise in size, shape, and texture. Grippy when held, but not "clingy" to clothing.
For the Taurus 856, I had gone from the large, slippery, original wood grip to a LOK-brand G-10 grip with finger grooves not well-placed for my hand. The Recoil Rider is lighter-weight, which slightly changes the balance of the 3" barrel gun when held, but is fine for shooting.
Both grips absorb recoil nicely, without being spongy, and are the best compromise I've found for shape, size, and texture. Totally happy with them, and with David's quick and friendly responses to emails.
