Pachmayr Gripper Grip w/Finger Grooves Black for Ruger Special Police 03175

YES! This grip will fit the older model of the Ruger Security Six with 150-xxx serial number. I recently acquired an older 150 series Security Six with the original walnut grips. The ergonomics of the grip were pretty bad, especially using .357 ammunition. The grip was simply too narrow. I started the search for something after-market but since this frame design was phased out in 1974, it was almost impossible. This frame has a 'square butt' design and the follow on model (serial number 151-xxx) had a rounded butt. There are some older grips by Herett and a few others available if you search ebay etc. but they were $75+ and were wood. I talked to a half dozen people who do custom grips and there too I was looking at the same cost. Even then, of the 6, only 3 would do the job and all of the grips were wood, bone etc. and no rubber. I personally wanted a larger rubber grip.I gave the Pachs a shot after reading multiple forums from folks who had done the same thing. Here's how it worked for me. Remove the screw and original grips. At the base of the metal frame butt, there is a metal roll pin with a smaller roll pin inserted inside of that. The smaller pin just slides out. The larger roll pin then needs to be tapped out. I put some WD-40 and Rem oil on the pin and let it sit for 30 minutes to loosen it a bit. Then I tapped the roll pin out with a small hammer. Once the pin was flush with the frame, I used a flat tipped tap (you can use a nail and flatten the tip a bit against a vice) to 'lightly' tap the pin the rest of the way out by catching the inside lip of the pin inside the hole of the frame. While I was doing all of this, I had slipped the grip inside of a heating pad on high, just in case I needed a little flexibility during the fit. I put the grip on and seated it. It is a snug fit, which is good, then I put the screw in. Charles Gudruth is right in his review. I had virtually no gap at the front (less than 1/32) and a bit of excess (3/8 ") on the frame rise just behind the hammer where the web of your thumb would be. This can be cut flush with an exacto knife left as is. I left it as is as I liked the additional recoil support.The grip itself is first rate. Rubber is not too hard or soft and the checkering is comfortable and not overly aggressive. I have medium hands (6', 172lbs) and it feels perfect to me. The difference when firing was very noticeable and gave me much better control for follow on shots using both .38 and .357 ammunition. I would highly recommend the product. Another great product from an equally great manufacturer. Product arrived in 2 days with Prime - thanks Amazon.

Arrived today and took just seconds to put on my Service Six. (Important: You have to remove the 5/32" by 3/4" roll pin on the bottom of the grip frame if you are replacing the stock grips, something that isn't mentioned on the package. The pin is there to give the stock two-piece grips two points of attachment. That is not necessary with a one-piece grip like the Pachmayr. ) I spread the seam at the front of the grip open about 1/8" and it slid easily onto the frame -- literally one second to install and another few seconds to tighten the screw.The result was a perfect fit all around -- I do not have any of the gaps around the edges that other reviewers have mentioned. The seam (which is on the front and bottom) is completely closed with no unevenness or protrusions.The grip feels far better than the stock grip. It's noticeably larger front to back, side to side, and top to bottom, and fits my average-sized hand better. The "feel" is really nice -- it's "grippy" without feeling rubbery. I also like that it covers the backstrap and gives some measure of padding to the web between thumb and forefinger as well as putting some rubber between the trigger guard and my middle finger. I expect my hand tol be much more secure and less likely to shift when shooting higher-recoil .357 loads. I will say that this is a utilitarian grip, not a showpiece. But it looks OK and, more importantly, it does the job a good grip should do. I highly recommend it.

Some of the reviews mentioned the seam not closing all the way. That was the case for me. They were easy to install, as long as you don't want them really all the way right, and then no matter what I do I can't get them to close up all the way. I knew that might happen from other reviews, and they are very comfortable, so I gave it 4 stars anyway. But, I wish the seam fit tightly. If the seam fits tightly for you, and you have bigger hands, it would be 5 stars.

Having owned several Pachmayr Grips for different pistols, I have never had a problem with fit. Decided to replace the Walnut grips for my Ruger Security six with Pachmayr grips. No matter how much I tried and tried to screw the screw down as far as it would go, there still remained a small gap on the butt end and at the seam lower end. The grips are still usable and do feel good in my hand, but I will find out next time I crank of some Magnum rounds if the grips will hold up..Going to keep my Walnut grips just in case. The only way for Pachmayr to resolve this problem would be another tie screw lower down on the grips. Oh and by the way my serial number start is higher than 151, so that is not the problem. I looked at the grips again an hour later and decided, that the gap is just too big and would let grime and dirt in. Sent it back to Amazon for refund.

Just like my dad had on his security six. The look and feel great.

These grips did the job for my Security Six. But as with other reviews, the one piece design does have its flaws. You cannot get a true fit with these grips. See my pics as to the gaps that you will experience. As such, it only gets 3-Stars. I did "warm" the grips before applying. That is recommended. But still you will have gaps. Plus, if you try to crank down the screw, one end will protrude from the other side. That is bad. My plan is to grind down the screw and see what happens. I also plan to apply some Loctite to the grip and then pace in clamps to hold together. I don't like the idea of moisture getting into the grip and handle. The Pachmayr is a good grip. I really like the feel compared to the original wood grips. But don't expect a perfect fit because it does not exist. You have to amend and modify. It is what it is.
