Twisted Industries Sumo handle 9mm cycling?

I believe that a few members here have reported that the Sumo handle works fine in their 9mm S2K. I almost ordered one for mine today, but gave up after about the 15th time the "Happy Harrytober" popup advertising their sale on magazines interrupted me and made me click the X to close. I guess I got annoyed enough by it that it turned me off to the purchase. I do not want any magazines no matter how much they are pushing them!!!!!

enough on the rant..

I received a fair amount of suggestions and such in my post regarding making my sub wife friendly. I have taken them into serious consideration and thank you for the replies. I believe my biggest challenge is going to be to get my wife to hold the gun in a proper manner. I handed it to her last night to see what she thought about optic height on it and it was as if the optic had a spider on it and she wanted to pull her head way back and push the S2K way forward....OK, we have work to do....

Back to topic at hand. I have noticed much benefit from the piece of washing machine hose that I have slid over the charging handle giving it a softer and larger diameter to pull. It aids me enough that I am tempted to leave well enough alone and leave it as is....but I hear many positive reviews on the Sumo, primarily in 40 and a few not so positive when used with brass bolt.

I think I would prefer to pay less and choose the Sumo over the heavy bolt as I have heard of factory and extended charging bolts breaking anyway. I would appreciate some input concerning the observations those of you that use it have noticed.

1) Does it still cycle wide range of load charges and bullet weights properly or heavily favor stout loads?
2) Does it change the trajectory of the ejected brass
3) Do you notice less "blowback" - I read somewhere where someone believes it helps as bolt stays shut the extra millisecond - hadn't thought of that before
4) any affect on jamming - I shot some 115gr loads and had some empty cases jam - as if stovepipe but still facing forward- I read posts on this issue. At least one mag had weak spring and I changed it but have not been out to test again. I am not sure if the ever so slight reduction in cycling speed makes any difference
5) Do you just seem to like it better for other reasons unknown...you just do...
6) I have heard that with the S2K, one can do the rifle version of "limp wristing" and have cycling issues if not holding securely to shoulder

Since I reload, if it drops empty brass more uniformly it is worth it for that alone.

I would not go to poorhouse if I bought one and decided to go back to original, but as I have mentioned before, I have a drawer full of "upgrades" for things that just weren't and have been removed. I originally has the double length in mind instead but still too small of diameter for comfortable grip to me.

Thanks again for your time.

Funny thing, I almost backed out of ordering because of that stupid Halloween magazine sale. The X to close the window was right next to the refresh button on my phone and extremely annoying.

I ordered one anyway and plan to test it with Wolf 115gr steel case, multiple different brass 115, PPU 158gr, and HST 147+p and I will report back after I do
I decided to bite the bullet and suffer through the ads and order tonight. After the sixth time the popup came back, I once again got fed up and called it off. I guess I am just a fussy jerk that does not want to be annoyed and pressured into buying something that I do not want. I even hooked up second monitor in hopes of moving it to that monitor to keep it out of the way, but must click the x only for it to come back on the same monitor trying to look at their other items as to combine shipping. I would have bought if free shipping, but trying to buy more just to feel I am saving on shipping only to be asked over and over and over again to buy magazines I feel is poor business practice. I do not think I even own any other specific weapon that they sell parts for. It can stay in cart until I do banking and clear my cache at which time it will be removed.

Having said that, this works both ways. I was planning on holding off purchasing a product from a different seller (not sure if OK to give name) for my Marlin 70PSS and I received very prompt email replies from them and they answered their phones right away and spoke with me politely and said that if I had more questions to call back and they would answer them, and should I choose to purchase they would be happy to sell but no pressure. The next morning I decided that they deserved the business and I placed the order.

Brasky, I would appreciate feedback once you try yours. It looks like I will be waiting awhile to order. I am unsure if they have black Friday sales, etc but if I wait until beginning of November, maybe could just as well wait inline then to see as well. I will possibly get more feedback by then and know how well it cycles lower pressure loads in S2K with/without recoil pad. While I felt no discomfort, my bad shoulder got red after shooting a couple hundred rounds last time out. I do not want that to happen to wife or it may fall out of favor. I am tempted to stitch a piece of leather around stock to take "sharp edges" for lack of better term off of it. May be too slippery then.

When I receive the sumo I'll post up a picture of the paracord I added. I wrapped it around the buttstock and through the sling loop. This helps change the feel of the buttstock and soften it up slightly plus I have 15-20 feet of paracord if I need it
This is exactly why I choose to ask questions on boards. My son has a HiPoint carbine in 45ACP that we have only had out twice as he would rather play video games with his friends. After feeling cheek slap on that, I took some advice for wrapping paracord around it. Unfortunately, I have not had it out again after doing so to see if it helps. I have more fun shooting the 380ACP versions I bought for my wife and daughter to go along with my daughters Browning 1911-380 which is an awesome pistol for those with small hands. Why buy reloading equipment for just one gun? Excuse to buy another was well received. To be fair, I gave wife and both kids the lowly hi points for Christmas last year. The 380's have been flawless (45 not shot enough to comment one way or the other) and I would highly recommend them for someone that reloads. Economical or ugly does not necessarily mean junk. I would consider a Sub2K in 380 if it were available as I can quickly and economically crank out the loads on my Dillon 550B.

I prefer not to take 9mm and 380 to the range at the same time. I only do so if I only take loaded magazines and no loose ammo as to avoid going in wrong gun. That is how wife ended up with hi-point 380 instead of hi-point 9mm. Mags too similar. I was going to buy the wife the 9mm sub2k last year instead of the hi-point but it took until September this year to find a multimag version to share mags with Marlin camp 9. I know that the Glock version may be ideal, but wanted compatibility.



I may try a slip on recoil pad just to see if gun functions with lower recoiling rounds, but may very likely go the paracord route as mainly trying to take aggressive edges off. "Why didn't I think of that?" Sometimes the obvious just isn't so.

Thanks for the (not so) obvious tip. It seems that I do not have to look far to find someone smarter than myself.

I put a Sumo handle on my 9mm gen 2, no issues running Aguila or Perfecta 115 gr, AE subsonic or PPU 147 gr. Recoil is dampened slightly. A nice upgrade but I don't notice a significant change in ejection pattern. For me the best part is the wider shape, fits my finger better. I like running heavy buffers in blowback to slow things down, take some stress off the ejector. I may still try the brass buffer as well after I run more rounds thru mine.
Thanks for the detailed feedback verifying what cycles. I like what I see in the pictures of the Sumo as it looks like it would be easier on the finger as you have verified. I wish there were a double length one of about the same weight, meaning a lighter material to offset larger size. I imagine the sumo is hardened and tough to drill and tap. I would consider adding a section of aluminum rod to the end of it to lengthen it if need be. Who knows, maybe the wife will be OK with sumo. Waiting till November as spent too much money lately. Hopefully annoying ad gone then or changed to discount on Sumo handles.
My sumo handle was supposed to arrive Friday and I was going to leave a detailed review after putting some rounds down range, but the package has been "delayed". Hopefully by next weekend I can leave you some feedback and photos
I understand delayed. I called Kel Tec last Wednesday with questions on front sight removal/reinstall and heavy weight bolt. I already had what I figured I wanted to order in shopping cart and saw that for about $5 more I could get priority mail rather than first class. Since wife only makes it to range on the Saturdays, I went ahead and inquired on the turnaround on shipping and said no point in paying the extra $5 if would not come until too late to use Saturday (yesterday). I was assured that if I placed order Wednesday it would be here Friday via Priority. I placed order a few minutes after hung up (the time it took to add thread protector nut if remove front sight to cart and complete checkout), but did not ship until late Thursday and get here until 6pm Saturday. Wasted $5 as I figured it would be. It is funny how I would pay more for the parts without hesitation, but get totally upset and mad when I pay extra for shipping that proves no benefit. I am one of the few that would also rather see something sell for $30 shipped rather than $20 with $8 shipping. Although still pay more it does not seem like paying a large percentage of price of product for shipping, which I realize is already added in the price.

I appreciate your efforts.

Here is a photo of mine with the sumo handle. You can see how I added paracord to the rear as a makeshift buttpad. I originally had this all black which looked better, but then I decided to order OD green accessories from different companies and as you can see they aren't even close to matching. Oh well it is growing on me

Century and Brasky, I was just looking at Brasky's S2K above and has the thought of...."how about cutting a piece of stiffer, closed cell foam and tying that up under the paracord for a recoil pad?" A bit more cord to cover the whole deal, and it should be something. Thickness is dependent upon whatever you desire.

I only had this thought, as I am a cheap bastard. That being said, I must admit that after purchasing and installing an Advanced Technologies Int. recoil pad, I am very impressed with recoil reduction and overall feel of the carbine. I feel your pain, and for only $26 I have a great pad. A small thing to consider, but it is easily taken off and put back on, if need be.
The foam I was thinking about is along the lines of a sleeping bag type of pad foam.

steel case is a no-no with the subbie

Screw the paracord http://www.convergentdesignsolutions.com/store/p78/Cheek_Pad,_Hi-Point_Carbine.html

Yeah right. I have over 600 rounds through mine and most were steel case and it looks new inside still. Many steel cases have hardness levels similar to brass. It is not going to hurt the sub

The fact that it has not caused you problems doesn't mean it might not cause them for someone else. Kel-tec does NOT recommend its use, and on this subject we will parrot their line.

I didn't say steel is too hard, and will cause undue wear. I shoot Winchester Forged in several guns. Steel case Wolf, Golden Tiger, Tula in 9, 223, and of course 7.62x39. Keltek doesn't want you running aluminum either. If the factory tells you in your owner's manual tells you no? They might know something.
I didn't have a lot of time today but I shot the following:

-17 rounds of Remington brass 115gr fmj
-50 rounds of Wolf steel 115gr FMJ
-5 rounds of PPU 158gr subsonic

All of it functioned as normal, I did not notice a difference in recoil or ejection. The sumo does make it easier to charge though

I really like this idea (paracord butt stock wrap), and wonder if you could share any tips for how you did that weave. How did you start/stop it, for example?

Is that standard 550 paracord? Or milspec 750 paracord? The 550 (7 strand) is about 3 mil, meaning should fit between the fins maybe too easily, the space between the fins being closer to 1/8" (4 mil). The 750 (11 strand) paracord is a little over 4 mil, so would have to be "squeezed" between the fins, so which did you use?

Thanks in advance for your input.

Stay low, keep moving,

Craig
I have no clue what kind as I bought it at Walmart. I started by tying a knot in the round sling loop then wrapping as tight as possible starting from the top and going down then below the sling and when I got to the bottom I went back up and tied it to the round sling loop again
