RUGER MK II. INSTALL AND INSTRUCTIONS VERY EASY TO UNDERSTAND. THIS PART SOLVES ALL PROBLEMS WITH INSTALLING THE MAIN SPRING HOUSING. WISH EVERYONE KNEW ABOUT THIS AMAZING INNOVATION.

45Flattop (from RugerForum.com)
I ordered two after reading John Taffin's remarks in American Handgunner
magazine recently, one for a MKII KMK512 and one for a much older, circa
1967 RST-4 and they both fit and work perfectly, for reference, the RST-4
is serial number 474XXX if anyone cares to set up a MKI/RST timeline on
determining if the HSS will likely fit their particular gun.
NOTE: on this website, on the "Compatibility" tab, we are compiling this info, if anyone else would like to contribute your info. Thank you,--Tom, HSS Corp

I found them and ordered 2. Gave one to my friend that hates his Mark III just because of taking it down to clean it. He has not had a problem since his install. Thanks for a great product.

I emailed HSS to ask why MK II/III & not MK I. Got an email back & it turns out the '70s MK I's had an alignment problem when drilling the cross pin holes. Some would fit, others wouldn't. My MK I is early 70's. I went ahead & ordered 2, MK I & MK II. They got here much faster than I was able to get the time to get them installed. The MK II was no problem. The MK I took some effort, but I did get it in. Great product & it works just like advertised. Highly recommend it.

After years of aggravation, THANK YOU!

Thanks for making such a great product!!! Easy to install and now saves me a lot of stress when putting my MkIII back together!!!!

Installs and works perfectly with the Volquartsen lower (clone for Ruger MKIII). Please notify me when you get a similar product available for the Ruger 22/45.

The Hammer Strut Support arrived here very quickly - I installed them on a Ruger Mark II and Mark III and as you said, very easy. Great product! I have recommended it to my friends.
Dec 26, 2017
I successfully installed both of them, one in an ancient yet well preserved Standard Model from 1967 and a new until yesterday afternoon, MKII Target. Both work precisely as advertised and I am past satisfied.

recv'd my HSS and it was in my TALO RIO-edition SS Mark III within one minute after taking off the grips - excellent fit, easy install, and indispensable! thanks!

I have a MK II that I bought used about three years ago. I had the common struggle, at first, when going through the usual struggle to take down/clean and reassemble. So, I have now done so more than 100 times. But, the learning curve was a challenge. With the simple installation of the HSS, it now couldn't be much easier. Thanks so much for this excellent, inexpensive part.

Thank you very much, your device is already making my reassembly of my Ruger Mk I and Mark II a lot easier. Your product works even in my Mk I. Excellent product. I sure will tell any of my friends and any one than I'm coming across at the Range, that will has a Ruger 22.
Thanks again wonderful product.

Finally got around to "try" & fit the strut support in my MkIII. After what seemed like hours of watching videos & it not sliding into grip, I finally found a video that showed it had to be tilted to drop in. I just never noticed the frame was wider once inside. My bad. Even so, you might mention this fact in future instructions. It now works as promised. Thanks.
NOTE: HSS Corp website added HSS installation comment about this. Thank you-Tom

I made this improvement on my Ruger MK III and made a review of it and now I am doing another review after doing the same to my MK II and as with both pistols, I had absolutely no issues when firing them at the range and the installation was simple and took about ten minutes. This modification will save a lot of frustration and stress when reassembling the firearm and the Ruger engineers are probably kicking themselves for not thinking of it in the first place. Happy trails and God bless America.
Nov 20, 2017
I have told how wonderful your product is. Gave your address and phone number. It took about 2 minutes to install each and now I don’t have to buy a new gun just to keep it clean. Hope you get a whole lot of business. God bless and thanks again.

Just wanted to let you know I received the 2 hammer strut supports I ordered. I installed one on a Ruger Mark II and one on a Ruger Mark I. Both installed easily and they worked great. Thank you for bringing this to market. Mark me down as a real fan and keep up the good work. Now, since I am a south paw, please dream up an ambi safety for me. (Smile). Thank you again and many kudos to HSS Corp.

I hope you are happy with yourselves. Your little $17 piece of metal saved me about $500 to $600 on a new Ruger Mark IV. Seeing as you were so helpful in making my Mark II easy to service and clean, maybe you can suggest what I can do with my extra and unneeded $600.
Seriously, a brilliant device. You saw a problem and devised a solution. Honestly I think you should charge more than $17... Seeing as I already have mine.

Received my Hammer Strut Support yesterday, and installed it just as you say. Being my first, it took a little extra time, maybe 10 minutes, but it went in and it works! I have always hated to clean that pistol, because it is such a SOB to field strip and re-assemble. This really helps. Will spread the gospel wherever I can.

I saw an article in Guns Magazine written by John Taffin about this item and ordered one for my Ruger MKIII and it took about a week to get it. I installed it in less than ten minutes, took it to the range the same day and fired 200 rounds just to make sure that the part did not interfere with the function of the pistol. My MKIII worked flawlessly with absolutely no issues at all so I have ordered another one for my Ruger MKII pistol. Bill Ruger is probably looking from above in awe? God bless America.

Just installed my HSS in my Ruger standard. Made in 1978, serial number starts with 14-. Perfect fit, no problem. Thought it might be helpful to you to know.

Made time this morning to install Hammer Strut Support in My Ruger MK 1 Bull barrel.
Went in like a dream. Will pass word around the indoor pistol range.
Nov 13, 2017
Received it today in the mail. Installed it tonight. Thanks. Fits great. Looks like a great product. You should have worked for Ruger.

Tom G (customer),
I installed my HSS hammer strut today, am very happy with it, but would suggest in your installation instructions that it should state that the magazine should be left in , I fought it until that come to mind and ,viola, went together in a snap.
NOTE: HSS Corp website added HSS installation comment for MK III pistols to have magazine installed to enable hammer movement forward (hammer fired position). Thank you-Tom (HSS Corp)

The strut was easy and quick to install. Reassembly of the gun was a breeze. I will be shooting my mark 11 much more often because I no longer dread the reassembly after cleaning. I hope the inventor makes a pile of cash.

Tom, I just installed an HSS in my MK III Target pistol. Piece of cake. Video is excellent. Now to do my Competition MK III. I shared the video with the Ruger Face Book page. I thank you and wish you success in your endeavors.

Just wanted to thank you for developing the HSS. I've had my Mk II for nearly 20 years and have shot it only 3 or 4 times because it is such a pain to reassemble after cleaning. Now that I'm 70 years old I can start shooting my favorite 22 pistol again on a regular basis.
The installation was so easy....using a pair of my fly fishing forceps to hold the hammer strut I was able to slip the HSS in place sitting at the kitchen table.
Perfect, and again thank you!

Ordered two. Arrived quickly. Installed one in my Mark III Target easily. Very simple install. Second one is for my daughters Mark III. Five stars plus!

Just installed my HSS in a NIB MkIII. I had to drive the pin and the mainspring assembly out with punches. Other than that it was a piece of cake.
Previously I had a MkII and seemed to always have trouble putting the thing back together. This time around I decided to take a proactive approach right from the get-go; thanks to Tom's brilliant and simple invention. Thank you, Tom, for eliminating future angst and frustration. :-)

Best thing I've ever done with my Ruger Mach 2 thank you H S S Corp.

I saw it on Ebay. I asked in another thread if it was a solution to a problem that I really did not have. Then I decided what the heck and ordered it to give it a try. I never had many problems taking mine apart or putting it back together, but the strut support seems to be made nicely and works well on my Mark III.
March 1, 2017
I got mine a couple weeks ago. Works great.
Problem is it cost me a lot more then I needed to spend. When I took it apart to install and give the pistol a good cleaning I decided to order a Volquartsen accurizing kit with stainless trigger and the part to eliminate the loaded chamber indicator. Lol
Turned her into a mark11.

"Hammer Strut Support
.....so I welcomed the current models (Ruger Mark IV) with open arms.. But what about the other millions of Ruger pistols out there of the same old design? Shouldn’t someone come up with an easier way? Well, someone has and it is a simple solution to a vexing problem which has brought some of us to the brink of drink and not so gentle words.
HSS has come up with a well thought out simple little addition to the Ruger Mark III and Mark II semi-automatic pistols, which makes reassembly so much easier. This little gadget is relatively easily installed without special tools. It is called the Hammer Strut Support by the company of the same name. This little gadget is about 5/8 inch in length with the channel through the center.
….It permits easy installation and allows the mainspring to be installed correctly and hassle-free all for $14.

"SUPPORT YOUR RUGER
Pop quiz. Why did Ruger come out with the Mark IV semiauto rimfire? Was it A) because IV is greater than III, B) because they love
Ro- man numerals or C) because the Mark III and
previous versions were bears to reassemble?
Owners of Mark III and prior guns know the answer is C.
But what if you're happy with your Mark II or III pistol and don't want to buy a IV? Enter HSS Corp. The company has come up with a support that keeps the pesky hammer strut from getting underneath the lower cross pin (sear spring stop pin). If that happens,the gun won't operate when you reassemble it, and you'll have to remedy it just to remove the bolt
when you try to disassemble it to figure what's wrong. It's not fun.The Hammer Strut Support $14, (HAMMERSTRUTSUPPORT.COM) fits all Mark II and III pistols except for the 22/45 versions, and it's simple to
