[Set] R601H JW3 TTI Combat Master (upgraded version) [JAG Arms] + Hi-Capa R501/R603/R604 Long Magazine - Black [JAG Arms]

Out of the box eine sehr gute "sidearm".
Ich habe jetzt ungefähr 1000 Schuss damit gespielt und hatte noch keine Probleme.
Der Blowback fühlt sich gut an, mir sind keine zu großen Fertigungstoleranzen beim Schlitten aufgefallen, da wackelt nichts rum oder bleibt stecken.
Das bucking "MR.Hop 60" von Maple Leaf rundet das ganze noch etwas ab.
5/5 würde nochmal kaufen

Unglaublich gaseffizientes Magazin noch nie Probleme beim Feeden gehabt und es lässt sich sehr leicht befüllen. Leider hat es keinen Schutz für das Gasventil am Boden wodurch leicht Schmutz hineingelangen kann. Deshalb nur 4 Sterne

Great pistol and overall performance. Has a really nice kick to it when firing and the looks are absolutely amazing! Sadly tho my slide catch broke after trying to fix a locking problem. The slide catch stuck very good at first, but putting it back made it stick less to the gun, in just a few shakes your slide catch would just fall off. After reassembling it the slide would still not lock back if there was an empty mag. I tried to fix it for HOURS but eventually the slide catch snapped in two. The pistol still usable, but I had to attach tape to both sides of my pistol just to make sure the pin didn’t fall out and it has kinda lost the realism to it…
My only advice is to be careful with the slide catch, it’s thin and can break easily if you’re not mindful.

Amazing pistol, without even changing the bucking or anything just normal maintenance the slide is fast the recoil is not too little but not too much so it feels good to use, it's accurate and if paired with an extended magazine it can be a real menace. I've used it in cold and warm weather with black, red and green gas.

The one thing that everybody needs one in Airsoft. After some time one is not enough. And after some time two is not enough!! This one in particular is great cause it can hold many BBs!! Fast package and well delivered!

This looks so slick in the Pit Viper. Working flawlessly so far. It has of course higher capacity which is always good and just has a great tactical feel to it. It's a must to make sure you don't run out of ammo in the battlefield.

⭐⭐⭐⭐⭐ Hi-Capa R501/R603/R604 Long Magazine – Black [JAG Arms]

This long double-stack magazine converts a Hi-Capa into a persistent field tool. Construction feels sturdy. The increased tank capacity allows two or more full strings of fire per fill depending on gas and BB weight. The feed lips and spring provide reliable indexing with no hesitation. With the magazine installed the pistol sits a bit heavier and that extra mass actually improves recoil control and target follow-up when shooting fast strings.

Field performance: in both speedsoft and IPSC drills the longer mag reduced reload frequency dramatically. In real games I often only needed to reload once or twice per engagement period. Gas efficiency is excellent when paired with quality green gas and the mag’s valve holds pressure even in cooler conditions. Loading BBs takes slightly longer because the loader window is smaller, but that’s a minor tradeoff for the sustained shooting time it gives you.

Practical tips: carry a dedicated extended mag pouch or a modified pistol-mag pouch because standard pouches can be tight. Keep the fill valve lightly lubricated with silicone oil and avoid overfilling. If you move between platforms, double-check compatibility with non-JAG Hi-Capa variants; most users report cross-brand fit but always test before a match. Overall verdict: the long mag is a high-impact upgrade for anyone who wants capacity, gas economy, and steadier handling without sacrificing feed reliability.

⭐⭐⭐⭐⭐ R601H JW3 TTI Combat Master (upgraded version) [JAG Arms]

The upgraded R601H is the most reliable and durable GBB sidearm I’ve used. I average about 2,500 rounds per month through this pistol and it still runs like new. The upgraded magazine never leaks and its enlarged gas reservoir plus efficient feed design means I use noticeably less gas per session compared to standard mags. In practice that equals fewer refills and lower running costs during long weekends of play.

Out of the box the external quality stands out: CNC slide, tight tolerances, and a nicely stippled grip that gives solid purchase even with sweaty hands. The slide action is smooth and the trigger is clean with a short reset. Accuracy is very good for a stock pistol; follow-ups are quick because the trigger and reset are predictable. Feeding is consistent and reloads are clean and positive.

Practical long-term notes: the hop-up/bucking can benefit from a simple upgrade for tighter groups, but even stock accuracy is competitive. The only recurring cosmetic note is that the fake brass barrel finish can show wear where the slide contacts it; this does not affect function. For longevity I recommend routine external cleaning, light silicone on moving polymer parts, and occasional valve checks on magazines. The upgraded mag’s reliability (no leaks) and gas economy make this pistol cost-effective for heavy users. If you want a John-Wick-style Combat Master that will survive high round counts and still feel crisp, this is it.

Hi-Capa R501/R603/R604 Long Magazine – Black [JAG Arms]
Summary: Reliable, gas-efficient long mag that adds both capacity and stability – perfect for competitive use.

Review:
I purchased this long magazine for my Hi-Capa and it has been a fantastic upgrade. The build quality feels solid, with a strong feed spring and no wobble once inserted into the pistol. Gas efficiency is excellent: a full fill easily powers two full loads of BBs without leaks, even in colder weather. What I especially appreciate is that the extended size not only increases capacity but also gives the pistol a steadier grip for competitive shooting.
For anyone considering it: make sure to use high-quality green gas and keep the valve lightly lubricated, as this keeps performance consistent. If you want both reliability and extra firepower in a single package, this magazine is worth every cent.

Best magazines for hi-capa pistols! This will allow you to run around not worrying about having enough ammo to last the round. Works in all Hi-capa brands, no problems or concerns between brands. I also like the way this matches my black 2011s!

Fantastic magazine, holds lots of rounds and gas
Its not even that uncomfortable and looks great on the pistol.
If u use the pistol as a primary this is the way to go.
Might be too big for some pouches

Great pistol, really impressed by the external quality
The slide feels smooth, trigger is light and fits very comfortably in the hand.
Ammo capacity and gas efficiency are good.
Only downside is that the slide will scratch off the paint on the barrel very quickly

Increased magazine for Jag arms pistols. I got it for my combat master and my sand Viper and it fits like a glove. The magazine has an increased tank of green gas and BBs and is great for extending the shooting session. The only flaw is that the loading window of the BBs is small and it takes a little longer to load the BBs but nothing impossible. Recommended

I have never used a green gas canister and I can tell you that it is really simple to use. This 1000 ml bottle is fantastic value for money and, despite almost 1000 shots fired, there is still gas inside. In addition, inside there is a small amount of silicone oil that will lubricate your replica. Recommended

Very nice pistol that replicates the Taran Tactical Combat Master from John Wick 3. The grip is a bit of a personal taste and I'm not crazy about it but it is completely hand made and not machine made like others. The slide slides well and the aesthetics are fantastic. The only complaint is that the fake brass barrel tends to get ruined after a while due to the sliding with the slide. However, other barrels are available as spare parts on the store.

Amazing magazine which is not much heavier than the standard sized one, the capacity is good enough to where in games where I am primarily using my pistol I only have to reload this big mag maybe once or twice per hour but this also depends on how much ammo you are looking to use.

I was afraid it would be clunky to carry around or have in the pistol but it actually is not any different than the small ones, you just have to get an extended pistol magazine pouch.

Great replica if you are looking for performance out of the box, personally I only switched the bucking with a maple leaf one using the TaiwanGun service.

Everything about this replica is great, smooth and easy reloads, very nice grip, smooth slide, the trigger is honestly amazing I could not see how it could get better which was really important for me as that is a massive part of accuracy and follow-up shots.

I would recommend this to any newer or older player.

Absolutely awesome and it shoots great !
Iv bought few models of these Army Ar. Models and they all shoot great. I just change the bucking because they come with bad ones . Other than that they are great !!!!
