Big Guy Posted January 25, 2017 Share Posted January 25, 2017 (edited) Any recommendation on a new comp for a 38 Super? Cheely titanium vs Akai vs EGW vs Bedell? Currently running 124s PD with N105. Ported barrel. Edited January 25, 2017 by Big Guy Link to comment Share on other sites More sharing options...
digi531 Posted January 25, 2017 Share Posted January 25, 2017 My last three builds I've used the Cheely titanium comp with a ported barrel and find the results are very satisfying. I realize people talk like the muzzle brake ( comps ) is the last word on gun performance, but some do seem to work better than others, but In my opinion not that significant. However, I'm using a full size gun with a 5.4 inch bull barrel and find the light weight titanium comp is great for this set up. The Cheely comp is somewhat unusual with the ports having a V shape design, narrower at the bottom, wider at the top, but in retrospect I'm not sure if the performance is anything drastic., but again, I like the design.

limited shtr Posted January 25, 2017 Share Posted January 25, 2017 I own over twenty comps the best I've tested was the lone star innovations titanium comp. I shoot 124 gr In my 38 super comp with 4 barrel holes ! My dad shoots same comp in 9 major with bad arthritis and this helped him to continue to shoot major .

Not being argumentative, just wondering ... How did you test the comps, and what criteria made you decide Lone Star was The Best? Link to comment Share on other sites More sharing options...
limited shtr Posted January 25, 2017 Share Posted January 25, 2017 Shot all comps on the same gun using the same load at 15-18 yards then shot a two target bill drill. I did this with every comp bedell, three different akai comps , Mclearn, old and new cheely , three brazos comps and many others. Some worked ok on different open guns but through lots of testing the lone star was the most constant dot tracking ! Link to comment Share on other sites More sharing options...
BallisticianX Posted January 26, 2017 Share Posted January 26, 2017 I've had a few comps and so far I am a fan of the CFD comp by Binary Engineering. The LSI comp previously mentioned is based off the same design theory originated by Binary Engineering. The CFD comp does the job and reduces muzzle flip better than anything I've tried so far. The dot tracking is consistent, therefore predictable, and vertical, no figure eight or side to side bounce.

ScottieShootz Posted January 27, 2017 Share Posted January 27, 2017 I also have a Binary comp, havent had extensive testing with it yet, but extremely happy. Link to comment Share on other sites More sharing options...
BeerBaron Posted January 27, 2017 Share Posted January 27, 2017 I have zero scientific testing other than shooting the things and the odd bit of super slo mo footage to observe gun behavior (which is also affected by the shooters grip). I like the combination of the cheely titanium comp with 3 popple holes. Ive also shot the new style Akai gill comp (this one had popple holes and a slot cut in the top of the comp) and I thought it shot nicely too. For me the first thing is it must be titanium. Heavy comps suck. I think there are are lots of good options at the moment and all work best when the rest of the 'system' (slide weight, popple holes, spring weights etc) are optimized. The cheely supposedly had cfd work done for its design. The binary comp has published some of the cfd modeling behind its design. The Akai seems a bit 'out there' but seems very efficient and the lone star seems well received too. My choice would be one of those 4. Link to comment Share on other sites More sharing options...

jid2 Posted January 27, 2017 Share Posted January 27, 2017 I've got CFD comps in-stock, should you be interested. Following the link to my vendor section/website. Link to comment Share on other sites More sharing options...
b18prl Posted January 28, 2017 Share Posted January 28, 2017 I've got CFD comps in-stock, should you be interested. Following the link to my vendor section/website.Jared,I re-barreled my 9 major to .38 with your comp, 5.4" KMM barrel with no holes in the barrel. Tried it with PD 124gr JHP and 9.0 gr of 3N38 chrono at 174xxx pf but the dot is dipping so I tried with 7.3 gr of Autocomp and found it's flippy but dot tracks nicer than 3N38!! What gives?

Sent from my iPhone using Tapatalk I use Autocomp. What I found to work best is to start with a low charge weight and work up. There is a transition where things just get harsher, without improvements to dot tracking. This isn't the case with all powders but was with Autocomp in my experience. So it's good to make sure you've found the sweet spot. What PF is the Autocomp charge? Edited January 28, 2017 by jid2 Link to comment Share on other sites More sharing options...

If the dot is dipping (below the line of sight) as it comes down, is your recoil spring a bit too heavy? Link to comment Share on other sites More sharing options...

How does it work with that lesser gas volume (e.g., with 3n38 or WAC)? Are barrel holes still recommended to reduce vertical motion? How many, what size?

I used 7.3 gr of WAC and was making 172-173pf then I tried 7.5 and got 175pf but felt harsher than 7.3gr. I'm thinking about putting some barrel holes for 3N38?Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
jid2 Posted February 2, 2017 Share Posted February 2, 2017 I run 9mm Major and the comp works well. I personally like two 3/16" holes in the barrel. But that is totally a choice, it will flatten things out, but add more impulse to the hand. Holes will only help drive the gun down, a comp will drive it down and pull forward so you choose what to do with the gas. For my setup and Autocomp I actually found my gun to run best just a touch under 170PF. So I think I am around 168-169PF. Past that is was just harsh, with the dot tracking staying the same.

b18prl Posted February 2, 2017 Share Posted February 2, 2017 I downloaded the Autocomp to make 169-170 pf and you're right on! Just a little pop in the hands and dot tracks nicely too. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...

I assume you're running 124gn bullets to get that high a powerfactor with AutoComp, 9mm major and two 3/16" poppleholes? Link to comment Share on other sites More sharing options...
