    Thordsen Gen II vs. Sparrow Dynamics vs. Strike Industries grip comparison

    This is going to be a looooong post with lots of photos. It's going to be spread out over several posts because the forum only allows five photo uploads per post. I’ll try to offer as much useful information and opinion as I can, but feel free to ask questions. Other than that, I hope everyone enjoys the reviews and I hope my opinions help a few people looking at converting to featureless. As with any of my opinions, your satisfaction is guaranteed or your money back.

    For a really comprehensive list of featureless products, check out MudCamper's compilation thread.


    Flavors of Featureless: A Taste Test

    The featureless bug bit me at the beginning of the year and I’ve collected and tried numerous featureless setups in just three short months. I thought I’d offer my opinions and photos of three of my favorite setups to help others who might be on the fence about their featureless configuration.
    We’re going to take a look at three featureless grip/stock/safety setups today:
    1. The Thordsen Customs Gen II stock with Seekins Precision ambi safety
    2. The Sparrow Dynamics Grip with Sparrow Dynamics ambi safety and Magpul ACS/Strike Industries Stock Stop
    3. Strike Industries Megafin grip with Strike Industries Strike Switch


    GENERAL THOUGHTS
    I’ve also tried multiple kydex-wrapped grips, the Strike Industries Simple Grip, and the Monsterman grip, among others. The three configurations above were my favorite, but I’m still tinkering with the combos.

    Out of all the different parts I’ve tried, I wanted to specifically call out the Sparrow Dynamics ambi safety for exceptional design. The idea is so simple that I’m really surprised no one has made such a versatile and configurable safety before. In my opinion, it’s an evolutionary step forward from the 45- and 60-degree short throw safeties currently on the market. I was really, really impressed with how simple it made my manual of arms.

    I prefer a configuration where my trigger finger has access to as many operational controls as possible so that my off hand is free to manipulate everything else in my workspace and environment. I run Magpul B.A.D. levers on all my ARs for that reason. The Sparrow safety takes that one step further by making it much easier to manipulate the safety as well.

    I have big hands. I wear a size “L” glove when I buy nitrile work gloves at Harbor Freight. Here is a photo of my hand next to a Sharpie and a can of beans for reference:

    Thordsen Customs Gen II stock with Seekins Precision ambi safety:

    DSC_6488.jpg

    I really like the hand ergonomics of this setup. As you can see from the pics, it puts my trigger finger in an optimal position relative to the trigger. My thumb can still easily operate the left side safety lever, so an ambi safety isn’t a necessity like other featureless setups. I will eventually replace the bullet button with an extended mag release on this gun. My finger juuuuuust gets on the mag release right now. Thordsen Customs even includes a dehorned end plate to improve comfort as you choke up on your grip. This is a company that’s really paying attention to the little details.

    DSC_6501.jpg

    I’ve seen some complaints about how thin the grip area is, but I don’t think it’s any thinner than your standard A2 grip. You can always build up the grip with tennis racquet wrap or put on Talon grip tape. For guys shooting 3-Gun, or for anyone using this for home defense, weapon retention and control is going to be a really big consideration when selecting a featureless grip. The Thordsen stock provides the highest level of retention and control, in my opinion.

    DSC_6502.jpg

    The narrow cheek weld and lack of adjustability in the stock was a drawback, but not a dealbreaker. I think cheek weld will really come down to user preference, but I prefer wider stocks like the Magpul STR and ACS. The length of pull is the same as an A2 stock, which isn’t optimal for guys who like their nose to the charging handle. Look to the Gen III Thordsen if you want more LOP adjustability.

    It is the most expensive configuration in this review, at $144 for the enhanced Thordsen stock kit and $40 for the Seekins safety when buying from the manufacturers. Cost will be a major factor for folks with multiple rifles to convert.

    See next post for the Sparrow Dynamics Grip with Sparrow Dynamics ambi safety and Magpul ACS/Strike Industries Stock Stop.

      Strike Industries Megafin grip with Strike Industries Strike Switch

      Strike Industries Megafin grip with Strike Industries Strike Switch:

      DSC_6494.jpg

      DSC_6491.jpg

      Of these three setups, this is my least favorite. This particular rifle is only ever shot off a bench, either on a rest or on bags, so I thought a fin grip or kydex-wrapped grip would be comfortable, since I shoot benchrest with my thumb up anyway. I just haven’t gotten comfortable with this grip.

      My sense is that this is built for a very specific hand size. The front strap feels thin in my hands, and the left side of the grip has a ridge that stops your fingers from reaching past the grip profile. Longer fingers may need to actually grip the ridge instead of the checkered grip. This ridge forces the palm of my hand further back on the right side, with the fleshy part of my palm sitting well back on the fin. The backstrap slopes towards the fin at a 45 degree angle, and while it is ribbed, I don’t think it provides a good grip on the gun. I think a sharper 90-degree corner to the backstrap would lead to a firmer grip. I might try adding some rubber Talon grip to see if that helps improve the feel.

      DSC_6506.jpg

      I never use the thumb rest. It’s a great idea in theory, but the vast majority of ambi safetys on the market will rub against your thumb or push your thumb out to the edge of the rest. I don’t use the rest for my particular use case, but a lot of people will likely look at the Megafin thinking the thumbrest will improve grip control. I’m going to purchase another Sparrow ambi safety and try out various lever positions with the Megafin. I have a strong feeling that the Sparrow safety will really help thumbrest fin grips shine by getting that lever out of the way.

      DSC_6508.jpg

      Speaking of safeties, I’m a big fan of the Strike Switch. It’s FAST. Lightning fast. I think competition shooters will find a lot to like about this safety. Lots of purchase area and long levers provide plenty of leverage to make this the most effortless safety I’ve ever tried. This safety was really, really great with non-thumbrest fin grips like the Strike Industries Simple Grip, or a munkeeboi-wrapped grip. Push down on the rear lever to turn it off, and push forward on the front lever to turn it on. It offers both 60- and 90-degree throw, and comes with end caps for the shaft if you want to install it as a traditional single-lever safety. This kit lets the user set this up as a single left or right safety, or with both levers as an ambi safety. Great thinking on Strike’s part.

      The aesthetics will turn a lot of traditionalists off, but I really don’t mind it because it improves safety operation so much. I’ve gotten a lot of curious questions at the range about it and quite a few compliments from people who have fondled it on my gun.

      DSC_6504.jpg

      I am currently pondering how I want to change up this particular configuration. I’m leaning toward installing a Sparrow ambi safety to go with the Megafin. If that fails, I may reinstall the Strike Switch and go back to the Strike Industries Simple Grip, which I think is the better grip from their lineup. There’s just not enough ergonomic improvement in the Megafin to warrant its higher price over the Simple Grip.

      The Strike Industries Megafin will run you $39.95, while the Strike Switch is $65.95. My honest two cents is that if you have multiple guns to convert, and you prefer the fin-style grip, go with the Strike Ind. Simple Grip for $9.95.

        Very nice write up and feedback, much appreciated..

        I’m looking for the most comfortable and as close to a grip as one would have sans pistol grip- would like to get feed back on the grip wraps.

        I only have exprience with the Exile Machine grip fin which is great, but quite thick in the area my palm/thumb would rest on the shelf. The SI simple grip to me is bang for the buck, but doesn’t allow my palm to sink as deep into the grip and my thumb hanging doesn’t feel comfortable..just my experiences and I have small hands - Operating room Glove size 7.5 with size 8 over, double gloved or just mostly medium nitrile examination gloves

          Good write up. I love that JD bronze lower you have there. What happened to that Spikes lower? It looks like it came out of the trash.

          So far that Thordson grip feels best to me, too bad you can't cut it off and use a normal stock. I don't like the stock/grip combo design.

          I also have Sparrows here and so far they are the winner of the bunch. It was the only option my wife could operate as she has small hands.

            Awesome comparison.

            I think the Thordson is the most comfortable but I wish they made a version with a shorter length of pull. I usually have my Magpul CTR fully collapsed when I'm wearing all my gear. The Thordsen looks like it would be the same length as my CTR on the 2nd notch.

              Kydex grip wraps will give you a similar experience to the Simple Grip, IMO. I found that none of them really offer enough space for my palm to wrap the grip. My palm inevitably ends up resting against the fin. You might want to contact munkeeboi on this forum and see if he can custom mold you a kydex wrap for your favorite pistol grip and request a little bit more offset for whatever hand you use.

              LOL! I guess that's sort of what I was going for. The cerakote scheme is supposed to look like an old, beat-up copper penny. It looks great when the rifle is assembled. One of the guys at Gunfighter Tactical has his personal Glock done in this scheme and it's totally the tits. I had to try it on a black rifle. They really nailed the copper oxidation. I'll try to post a photo of the whole rifle next time I'm downstairs at my safe.

              Check out their Gen III stock. It uses spacers to adjust LoP. Their website lists the Gen II with a 14" LoP which is A2 LoP. I'm not sure what LoP at the second notch with a CTR is, but if you're shooting nose-to-charging-handle, that's most likely shorter than A2 LoP, unless you're a giraffe with gorilla arms.

                  Oh cool! It looks like the Gen III stock fits the bill. I like having a short 11.5" LOP. Thanks!

                    Fantastic detailed review! And great photos too. It is nice in a review to get hand size and shape for ergonomics reference.

                    I like how the FDE Cerakote turned out on our safety, the Odinworks extended mag release, and the B.A.D. lever... and how well it all matches our grip and the stock. That is an awesome build!

                    As a side note... on our website we have a note about colors of our safeties. We basically say that our colors don't match FDE or ODG, but do "coordinate" with those colors. But since you did a true FDE build, I feel you made the right choice to Cerakote those parts to match.

                    Nice job, and thank you taking the time to do this.

                      Nice review, I have tried all three styles myself. One thing that I wish the thordson would do is release a stock much like the magpul SGA, with a thicker grip and a steeper angle for the hand. I have average sized hands, but I found the grip way too skinny for my liking.
                      My rights aren't yours to vote away.

                        I heard their Gen III has a fatter grip, but I haven't tried one myself. I'm tempted to order one, but I'm running out of rifles to install them on!

                          You're very welcome! I enjoyed putting all these products through their paces and writing this. I took every setup through a whole bunch of mock manipulation drills, slowly and at speed--house clearing, malfunction drills, switching shooting hands around barricades, dropping to prone, and numerous reloads standing, kneeling and while prone. I couldn't tell a difference between your grip and a regular pistol grip once muscle memory kicked in. It really is a natural, comfortable shooting grip.

                            I was looking at the Thordsen for a while, but the Sparrow Dynamics (thanks to this review) has jumped in front, if nothing else because of apparent ease of installation (no need to disassemble buffer tube). I'm thinking of Replacing the CA legal M&P Sport II flap/fin grip, which includes an ambi safety. Will I need to replace that with Sparrow's clocked safety because of the thumb placement?

                            Also was wondering how Sparrow Dynamics compares to Resurgent Arms' solution.
