Great stuff here. Exactly the data I was looking for. I own a tti combat but I am wondering if I shouldn't just build a mete sft pro with a comp for much cheaper. Obviously I really only care about the recoil impulse. Very interested to see the canik video and if it tests lower than 21 deg avg.
Yes, sorry for the delay on that its been pretty busy couple of weeks. I am still trying to condense and revise the data from the 200 rounds we did the port/comp comparison data with (the data logger logged over 2300 data points). so I hopefully should get that out this coming week. I have already cut the middle of the comp and should have 100 rounds through that this week as well so that will be following shortly.
Great vid, though I would very much love to see the same type, detailed report in a comparison of this and Barrel Porting by LTT? I've also wondered if doing both would be a thing? Specifically for my 92FS (A1)
Ill see about adding the barrel porting to the list of testing. I just ask for your patience as it will take some time since we are currently working on a couple other projects, plus I have had some equipment issues lately. As far as having both (comp and porting) I would think you would run into reliability issues, ballistic variations and over all functioning of the firearm. With the dual port comp you already have to install a much lighter spring for it to function. Plus I don't think at this time LTT will even port a threaded barrel (most likely for that same reason). Thanks for watching and your support of the channel!
@@EmptyBrassRanch Thank you. Mostly wanting to know what would be best for my currently original FS (A1). Going with the comp would need a bit more changes. If they are close in functionality, I'd go with LTT's porting. Just cannot find any comparable testing out there. Thanks for all you do, no hurry.
What holster are you running with this? I have a tier 1 holster they have an open bottom so they can fit comps. Just wondering because it seems the rail portion is enlarged a bit
I never tried to holster it, I removed the stand off and have been trying other things. It does add a good amount of size to the front so holstering will be a challenge for sure.
That is what our numbers showed but this was also a very small data set. This suggested that without the comp we roughly had half a degree less perceived recoil than with the comp on (pretty much no difference). We are going to redo this with a much larger data set (100 rounds comp on/off) to see if that gives us more precise numbers to work with since this was so close. After that I think we will open the comp port up to accommodate the full size of the barrel port opening and run another 100 rounds to compare as well. Hopefully after opening up the comp the added mass of the comp with a full opening will give us less than what we started with.
This was just an experiment to see what we would get with the comp off. This was a limited data set that suggested something we did not expect (that the comp actually had very little effect, if any). I didn't want to further this video because now we will have to collect a larger data set to get a more definitive answer.
I have an M9A4, and was looking at the Jarvis versus the JMM, because the Jarvis can be fitted better, _AND_ because the Jarvis is steel - I _WANT_ the extra mass at the end of the barrel to help resist muzzle-flip. That said, I called Jarvis and spoke with a man there who said that they recommend the single-port compensator _IF_ a red-dot is to be installed on the gun. Otherwise there might be some reliability issues with cycling. However, I saw a RU-vid Short on here with the two-port Jarvis _AND_ a Steiner MPS on top of a Beretta factory red-dot plate. Now I have the Holosun EPS Carry, and it's _HALF_ the mass of the Steiner MPS. _AND_ I'm using a Dlah-designs Aluminum plate versus the factory Beretta steel. Curiously, I can't seem to find weight information on either the Beretta plate _NOR_ the Dlah plate, but considering that the Dlah has both a smaller form-factor _AND_ is made of a lighter material, I'm confident that my plate-&-dot is about _HALF_ of the plate-&-dot that the other RU-vid video was using, _AND_ cycling. I don't know what my point is. Maybe this; Jarvis recommends single-port if using a red-dot... but there's some evidence that the two-port can work with a red-dot as well, but it may be important to choose plate and optic wisely.
I think that is probably the safe answer that they can give. I'm sure as you said, with the right combination you could get the dual port to work with some light weight optics.
@@goodlife5825 I got dual port, actually came back yesterday. I put it on my M9A4 centurion so it has a factory threaded barrel. Took a little over 3 weeks
@@screamoXable awesome, I plan on sending my 92FS and having them thread my barrel. I'm going with the single port. I've done the trigger in a bag conversion and made everything steel again. Only thing left to do is add the Jarvis. It's gonna be sick
@@goodlife5825 I’d expect around about a month with your shipping to and from. I have yet to fire mine, waiting for thread lock to set. Also have to re zero my sight
Great vid, better numbers than expected. Would love to see one comparing the new S&W M&P9 2.0 carry comp compared to M&P9 2.0 metal frame as I’m looking at getting one of either, leaning towards Carry Comp.
So far I havnt had any issues but I only have about 600 rounds through this barrel using winshester 115gr fmj. I am working on putting this in the ransom rest to compare Accuracy and precieved recoil against the stock barrel and then order a new threaded barrel and comp to try next.
@@EmptyBrassRanch awesome! I had one of these barrels and I couldn't get anything to cycle reliably in it. I even went down to an 11 lb guide rod spring and still no luck. Happy to hear it's doing good so far for ya!
If I remember correctly it was just shy of 2 weeks time from when I mailed it to when it returned. I think they only had it for about 4 days before it was mailed back.
You can get the compensator kit with or without a guide rod/ lightweight spring. The guiderod in the kit I ordered was a steel guiderod with lightweight spring.
Review consisted of barely any shooting, no before and after recoil, description of effect is “better”, and try it for yourself. Buddy, this is a $400 setup for a $700 gun. Idk if I wanna just try it out
For normal cleanings, you really shouldn't need to remove the compensator. You are still able to remove the slide from the frame and can access all the parts to easily clean. It is recommended to only use Blue loctite (low hold) so you can remove the comp and/or to completely remove the barrel from the frame.
@@EmptyBrassRanch thank you for for the answer! How about the barrel? You just clean it from the front? Or can you still remove it? Sorry to be precious about it, but really want one of these loo
@@Thabosshoss Yes you would mostly from the muzzle but you are able to tilt the barrel enough with slide/spring/guide rod removed with compensator attached that you "could" get a cleaning rod in from the chamber end.
@@EmptyBrassRanch interesting! Would be cool to see a video on that. I have been comparing this to the PMC machine and the Beretta OEM muzzle brake. All seem like good options.
@@EmptyBrassRanchi want to send my slide and factory barrel to get fitted and threaded. Do they include a thread protector when they ship your slide back ?
