HatsanMod 25 Supercharger QE Spring Piston Air Pistol- .177 Caliber

This even feels heavy duty. It's a large pistol. So if you have weak arms or a small hand, this may not be for you. It's powerful and hard to cock, but seems accurate out of the box. It has dovetail mount ability, so i may add a red-dot later. It's not as quiet as I had hoped, but not as loud as some I have owned in the past either. Overall.. good purchase

I have the .177, I have been using JSB exact Diablo match 8.44 grain pellets. Excellent accuracy. The fiber optic open sites work great. Very bright. The trigger can be set to a very light pull; just back out the rear screw slowly and test each time. Be careful, you can get a very dangerous hair setting. Compared to my hatsan 95 and 125, this gun is much quieter. I mounted a hatsan 3x9 scope from my 125. I had to jury rig the scope mount oh, I could cock and load the pallet, but it functions well now. Some reviews say the gun is hard cock, I don't find that to be the case. And I should know, I am 81 years old and just had open heart surgery surgery 10 weeks ago.

I waited several months to get this. Box was damaged, but everything else was fine. It’s not extremely hard to cock, but hopefully it gets easier after I use it for a while. Only four stars because I had to wait so long for it to get here.

Added a CVLife red dot sight to it. Shoots OK, but dang....you gotta be Schwarzenneger to break the barrel on this thing. I hope it lightens up with use.

it's been really hard finding this in stock on amazon. i was desperately trying to replace the older model, with the slim muzzle. i did an oos order and amazon cancelled. so as soon as i saw this newer model, i pulled the trigger. i really don't like how chunky they made the muzzle/cocking handle. i assume it was to cut down costs, because it is all plastic vs the threaded metal one. the qe piston sound just as loud as the older non qe model. the pistol itself shoots just as hard. i did not chrono it, but testing it on drywall proves it is just as strong.

On my Hatsan Mod 25 Supercharger QE pistol the breech seal blew out after about 500 shots. I had never dry-fired it nor lubricated it, and there's no evident defect (eg. metal deformity) in the area that could cause this. Replacement seals are effectively unavailable in the US - Hatsan lists them but never has any. After all, why should they stock more of a small, cheap item that's essential to half a dozen gun models they sell, and that sells out immediately year after year? Crazy, right?The gun itself is accurate enough for my pest control use. With perfect aim it would hit within 1/2" at 40'. That's with a variety of 7.5-9.5 grain pellets; except not the Daisy Winchester round heads, half of which won't even go in the gun. I've seen the same comment on these pellets elsewhere, and someone explained that the Mod 25 breech is fairly tight.The supplied fiber optic sights, although roughly molded plastic, work well enough up to that 40' range, meaning you'll probably hit within 1" of where you aim. Maybe due to the recoil, the front red fiber optic rod fell out and won't stay back in. I don't want to glue it since that might ruin its function; and the factory doesn't glue them either.Also because of its typical airgun recoil, for accurate shots it's crucial to use the "artillery hold". Read up on that elsewhere but it basically means cradling the gun in your hands as gently as possible while pulling the trigger. Note that your hands and arms can be on a soft rest but must be actively controlling the gun's aim. Not doing this will easily cost you 1" in 40' accuracy.Moving to something giving a more precise view is a problem because this gun has serious internal recoil, even with the recoil damper. It's very hard on red dot units and no doubt on scopes as well. I have not yet found a red dot which will properly mount to the 11mm dovetail rails AND will survive. This isn't a fault of the gun - all spring air guns are similar, which is why red dot and scope makers don't mention them in their ads.Also be aware that these 11mm rails are not very 3/8" friendly. Meaning that a red dot unit designed and specified as 3/8" may not fit securely enough to stand the recoil. The BSA RD30 is an example. Note "designed" as opposed to "advertised". Many red dot units are designed to be 3/8" but the copy writers like to tack on "11mm" too since the two standards are very similar. However, their grooves are different enough to give some sight mounts trouble.So if you want to use a red dot or a scope you'll probably end up with an 11mm to 20mm (Picatinny) adapter. I've used this one which worked very well but of course increases the height:https://www.amazon.com/dp/B0BPPRB28H?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1From the factory, trigger pull is heavy and the travel is long. Both can supposedly be adjusted but although Hatsan raves about their Quattro trigger system they provide no info on setting it! Everything they publish on that is wrong and has been wrong for years. None of the various pictures and descriptions - even the manual that comes with the gun - match today's "QE" model hardware (!) AND they're inconsistent between themselves! When asked, Hatsan USA has no idea which trigger screw does what (!) and can't be bothered to find out from the factory in Turkey! Crazy, right?After some experimentation I conclude that the screw immediately behind the trigger (so, the front screw) adjusts trigger pull force. Turn it clockwise to reduce the force. The screw behind that one (so, the rearmost screw) adjusts trigger travel. Turn it clockwise to reduce travel BUT BE AWARE that if you go too far in this the gun will shoot as soon as you snap the barrel back in place which is VERY DANGEROUS. Better to leave this rear screw alone since too much travel isn't as bad as too much pull force.Some folks complain that the receiver is loose in the stock; but it's supposed to be. That's the design of the recoil damping feature.It does take considerable force to cock this. It's rated at 58 lb but that may be the 2014 pre-QE model which, as noted above, still dominates Hatsan literature. Using a bathroom scales I find it to peak at 45 lb. So if you can't press down on a scales with close to that much force, this isn't for you.Despite the minor issues I would be ok with this gun but blowing the breech seal is a serious problem, especially with no replacements. It could be just the gun I got, or not. As mentioned I see nothing about mine that would have caused it.

The media could not be loaded. This gun is huge, and at first I wondered if I had made a mistake. It's front heavy and awkward, but I found a comfortable grip and it feels pretty reasonable now.The fiber optic sights are excellent. Easy to get a good sight picture and lots of adjustment available on the rear. It was fine out of the box.I haven't played with trigger adjustment yet. The trigger is better than any of my other pellet guns. Not as good as a 'real' pistol, but very good nonetheless.6 shot groups at 10 yds. Easily 1" groups (except for the ones I threw, LOL).As far as noise is concerned, it's quieter than a Crosman pumped up to 4 or 5 or a GAMO with a fresh cartridge.

Only dislike is I didn't buy it a long time ago.The sights are great, but I added Lonsel Dovetail to Picatinny Rail then added a CVLife 1x22x33 Red/Green Dot Scope. Dime size grouping at 30' using .177 JSB Diablo Dome Exact Express 7.33gr. pellets. Makes a small hole in front of an aluminum water filled soda can and a 3" hole in the back.Killed a 3' water moccasin (I sincerely apologize to all snake lovers) at 10' and 2 shots. 1 in the middle of back so it would turn around and the 2nd shot blowing off its head using H&N Hornet 7.35gr.Crosman Destroyer 7.4gr will do good damage w/accuracy, the H&N Terminator 7.25gr are very accurate. And finally the H&N Hornet will go through 1/2 plywood. Oops.
