Gamo Swarm Magnum Pro Reviews

Easy to operate plenty of power for hunting all you need is pellets

Excellent design I wouldn’t change a thing, it would be nice if it came with two mags

Ten round magazine is convenient and easy to use

One mag is not enough I would recommend at very least two mags

I like the way it looks first of all. I put a UTG 3-12X44 scope on it and it wound up looking even better. I like the fact that it has an adjustable trigger but I did just order some M2.5X8 screws that should make the trigger even lighter even though it's good enough as it is. Really like the 10 shot magazine, people complain about it but I treat my guns with great care so I rarely ever have issues. It's super quiet for what it is. It's the ultimate survival rifle in my opinion. Nitro piston airguns last a rather long time and this one is particularly powerful.

I wish it was easier to clean the barrel but it's doable.

It is rather heavy but I figured out a way to hold it steady. I'm a relatively strong guy but my arms shake when I hold it like I would any other rifle. I use my left arm as a prop, I hold it closer to the trigger mechanism instead of out towards the barrel as one usually would. Works for me. The weight does help with recoil but beware, the scope stop feature on the Gamo rail is entirely necessary to utilize. This thing WILL move your scope due to how powerful it is unless you use a scope stop and/or an especially sturdy set of scope rings. I'm happy with this rifle overall, all I want to do is shoot it. There's nothing like hiking around a beautiful area with an airgun like this. It's fun and a healthy hobby in my opinion. I use H&N Terminator pellets and they work well, massive energy dump. I tried the Spitzkugel pellets but they aren't as accurate although they whistle through the air which is cool and the penetrate well. I suggest using heavier pellets, you'll get greater accuracy.

Put 500 rounds through mine so far very impressed. Great power and accuracy for a break-barrel. The scope is not bad not good. No range/windage indicators but it’s got a clear image. The swarm mags are great flawless function so far. The trigger is very mushy out the box but it’s an easy fix (see next). Stock feels high quality. A bit tricky to bring the rifle up to shoulder when it’s resting forward on a sling cause there’s nothing to get your thumb up under. That’s all Monte Carlo style stocks though. If you want to be able to bring the rifle up to shoulder super fast you might want the non pro variant. I haven’t chrono’d mine yet but from the videos I’ve seen online it seems to be remarkably consistent. Pyramid always brings great deals great service.

The trigger needs a special screw to turn it into a great sub 2lb trigger. It’s an m2.5 45x10mm. You can find them at hardware stores for less than a dollar. If you tighten it all the way the sear won’t engage or it could fire the moment it’s cocked so take care make sure it’s unloaded and fine tune it to where it’s safe. Look up a tutorial. Give it the ol’ drop test make sure it doesn’t fire on its own after fine tuning. You DO NOT want accidental discharge on a rifle this powerful. If you buy the trigger screw and a good AO scope for around 150$ you would have an absolutely killer setup for around $500. Honestly nothing beats it for that price. Nothing even comes close frankly. Gamo did really well with this one.

Clean the barrel before you shoot it. Mine came filthy. Rifle isn’t heavy but it feels heavier than I expected cause its length. I slapped a picatinny mounted split bipod on mine it’s way easier to shoot from a rest. It’s putting groups within a quarter at 25 yards. Be prepared for a workout when you go plinking. Happy shooting.

Extremely accurate right out of the box. The velocity is very consistent. Using JSB Match Diablo Exact Jumbo 15.89 it had an avg velocity of 852fps with a STD dev of 10. Even with the cheap pellets you could cover the 25 yd group with a half dollar.

Do away with the cheap scope and lower the price.

This is one very good break barrel. It’s not for the frail or weak though. It takes an effort to cock it.

Just received ours today! This air rifle is the best air rifle I've ever owned. Hands down! Thank you Pyramid Air for all your knowledgeable customer care service members. Thank you Gamo for manufacturing such a great rifle.

Nothing

Don't believe all the negativity you see or hear. I dare you to try it yourself.

This the most accurate springer I have ever shot. It is very pellet picky though. Not only is it accurate but it is very powerful . Multi shot mag has been flawless so far.

I can't think of anything I would change other than I wish it had open sites.

This is a very hard rifle to cock. It's definitely not made for young or small people. It is a brute of an air rifle for sure.

Plenty of power. Accurate. Better have some arm strength! But it does the job.

PyramidAir had the very best pricing, honest value (exact product, no knock off), great customer service and offered value pack pellet pricing (great to evaluate for the best pellet accuracy). Rifle: great power, still evaluating pellet weight but not the most accurate. I’ve been among the most winning at the range in accuracy with many varied firearms. This riffle isn’t that impressive (might be pellets or scope). I’d buy again at this price point that PyramiAir offered (no brainer) for pest control.

Ditch the scope (lowering the price, I’d demand that) for open sights or red dot (for most ppl.). Your shooting minimal yardage and anything further is ridiculous as accuracy suffers a lot (for clean kill, but ok for targets). Prices escalate when changing things and if doing so, probably best to buy something already made for necessary changes (better rifle). But if demanding my two cents, more accurate riffling (barrel) and better cleaning arrangement (prices start to climb).

I bought on special sale from PyramidAir. I wouldn’t have bought at full price anywhere, instead, I’d have bought a more premium rifle. I receive nothing from PA at all. It’s a fun rifle, does the job but with at least half missed shots due to accuracy (all clean kills at close range? Definitely not). Previously stated but I’d buy again at sale price. Use heavier pellets for better accuracy.

Very accurate, routinely put 5 in a dime size dot at 25 yds

I like the design, but the grip isn't the most comfortable

tack driver even the scope that comes with it you can get by with

I like everything I did add a tripod to it

It’s all about your pellets with this gun. If you ain’t got the right pellets, it’s not gonna shoot good but when you find the right pelleted, match quality air rifle.

This rifle is Excellent, I know that it is only an update of the previous versions Gen2 and Gen3i but it is still a very powerful and very precise rifle, I make good shots at 80 meters 87 yards

nothing, everything is fine

To break the cannon you need a lot of strength but you get used to it
