Well, I mentioned in another thread that I recently purchased two S2Ks, a 40 Stock and a G19 M-Series. I had not taken the 40 to the range by the time my M-Series arrived. I did not discover the M-Series until after I got the 40, and as hard as they are to find ANYWHERE for under $800 for stock models (have you seen what they go for on Gun Broker ) I grabbed the 40 at standard retail when I saw it. My “warrant” (Retired) side arm was a Sig P226 .40, I have about twelve Sig mags for it and thought the S2K was a perfect bug out companion.
I also used to carry a G26 in an ankle rig and a G19 in either a shoulder holster or inside the pants holster depending on the time of year (my agency did not like us having weapons exposed to the public in plain clothes). I had been trying to get an S2K in the G19 format for what felt like forever. I got very lucky when I saw them pop up on MCARBO and snatched one quick like.
All I had to do was pull the trigger on the M-S2K and it was over. The mushy, heavy, horrible trigger on the 40 ruined the whole gun for me. I was actually kind of pissed. Misplaced anger, I know, but, C’mon man! If I had waited, I could have gotten two M-Series and lived happily ever after. So, I made the decision and bought ALL the upgrades except for the scope mount. It looks awesome, but I am very pleased with my system, it is not as fast as MCARBO’s, but faster than the Midwest offering. I also like the flexibility of easily removing it for using just the sights (more on that later). All I have added to my M-series is a new front sight post, the RDL (rapid release) and the butt pad.
The wife took the twins to Mexico for a week, so I saw my opportunity to sit down and put it all together uninterrupted. Here’s where I started. You can tell the .40 is the bottom S2K.
and the “project site”…
I put the M-Series aside and got set up for the big install!
As far as the install went, I had watched the video, twice before starting a week and a few days before. I wrote down all the tools I might need to buy and had it all ready to go. I had no problems at all. I went slow and smooth (My steel coach used to drive in our heads that, “Smooth is fast, hurried is slow”). Paused the video and rewatched something if at all iffy. I also did all the suggested polishing. The two most difficult parts for me were…
Getting the pinned doohickey on the end of the recoil spring. It was more figuring out technique than actually difficult. I can see how someone with arthritis or weak hands could have trouble with it. My suggestion here would be to get a 2x4 and cut about 4 to 6 inches off of it. Drill your 3/4 inch hole in the middle and then follow the video (the new video on the charging handle install). I did the method Chris used, but think having a thicker block would give greater control over the whole assembly.
The butt pad. Once you get the holes drilled, putting it on is easy. Getting the holes lined up exactly is not at all easy. The entire process is awkward and doomed for failure if you try to rush it. Even taking my time, mine aren’t on perfectly. I asked my daughter (the one that had to stay for school) to look at it and she didn’t notice the slight overhang on one side. I really believe that MCARBO, since they do these regularly, could make a stick on template for the butt with precise locations to drill the holes. This would save an enormous amount of time fiddling and trying to hold everything in place while trying to mark the holes. Heck, I would have paid and extra 5 bucks for that! All in all, since they’re my guns, I wanted them perfect, not almost perfect.
Done with the 40
On both weapons, I installed Hi Viz front post sights. It was an easy swap out. These sights have a small fiber optic dot that works well in daylight. If you are like me and like to shoot with iron at times, or if your batteries die in your red dot, these are a nice and affordable addition. The next upgrade I would really like to see from MCARBO is a folding front sight. I have seen the Red Lion, I know people like it a lot, but I’m not convinced and am positive that Chris and his crew can come up with something better. I would rather have a foldable front sight and have the flexibility of using a higher RDS riser and not worry about trying to get the two to co-witness. With my scope system, a higher riser would get my face off the tube and provide a better field of vision.
Overall, I found the project somewhat of a challenge because I’ve never done anything like this before, but I am a big DIY guy with lots of tools and gun accessories.
One tip that saved me twice. When working with springs and little jumping pieces in the past, I would cut some mosquito netting into a 3’ x 3’ piece and drape it over the parts I was working on. Easy to see through and stops unwanted escapees. While cutting through Walmart, I went through the fabric area. I noticed a roll of the material that was really see through. The stuff they make the frilly part of a ballerina’s tutu out of (if you’ve had daughters, you probably know). This stuff was CHEAP! I got a yard of the stuff for about $2. It is folded twice also, so I got a shload of the crap for future projects. Worked perfectly and saved a flyer on me and is a lot cheaper than cutting up good mosquito netting. I also used it to drape over the parts while I was polishing them. It did a great job at stopping dirty polishing compound from spraying all over the place. Just don’t let your Dremmel touch it or you will have it wound around the Dremmel bit like a big cotton candy (speaking from experience ).
I highly recommend that you try to do this whole upgrade to your S2Ks and I actually enjoyed the whole thing (except for the 20 minutes on my 60 year old knees looking for a screw I thought I dropped on the floor, but was really stuck to my magnetic screwdriver. F Bombs galore!). Save up and buy everything at once, set aside a half a day and go to it. If you don’t have the carbon screws and grip pins, chances are you will tear up the aluminum crap pretty quickly, if not the first time you take it apart.
My biggest question now is… Do I tear my M-Series down and polish the parts they didn’t? I can see that neither the feed ramp nor chamber were polished so I’m sure the hammer and sear weren’t either. It is sort of a compulsion with the S2K. If there’s something you can do to make it better, you want to.
Double companions. Very pleased. Now I have to decide which goes in the car and which goes in the bug-out bag. Oh, life’s tough decisions!
