Hi, Another good choice! I initially ran this machine pistol with a red laser sight on the lower 20mm rail. This worked well for aiming but in bright sun conditions the red dot reflex on the upper rail is a far better choice. Shooting felt cleaning pellets is really the only risk free way to clean the barrel since you cannot access the breech. Hope that you enjoy. All the best.
@@Incognito1-1 Just got my MP9 and love I love it. Just ordered P85 Blowback, looking forward to it too. Your review is spot on. Ordered similar sights as yours, they look awesome. 😉👍👍👍 All the very best to you as well.
Even though they are discontinued, managed to get one NIB. Very nice, except that with its open sights it appears to shoot low. The same problem as with my PT-85. Why can't Gamo get such easy things right?!? It's irritating to having to buy an extra reflex sight to get a usable airgun.
Hi, The MP-9 has got windage adjustment on the rear sight but you are correct that the elevation is fixed. But the ugly truth with CO2 guns is that the POI drops gradually from the first shot to the last shot out of a cylinder. So even if you could accurately set the elevation on the iron sights it would only be accurate during one part of the cylinder life. In practise you observe your POI and use that knowledge for the subsequent shots. If you really need constant muzzle energy and consistent POI then you need to invest in a regulated high end PCP pistol. All the best.
@@Incognito1-1 My MP9 shoots some 3-4 cm low @ 5 meters with a fresh CO2 capsule. Haven't a change yet to test what happens @ 10 m. DIfferent pellet weights may also have an effect. I principle, gas pressure should not drop just because the capsule is consumed, because vapour pressure of CO2 only depends on temperature. But the capsule cools down when CO2 vaporizes, and if one does not give the capsule time to warm up between shots, pressure definitely drops. The less CO2 is left, the more per shot it cools and the more notable this effect becomes. I do own a couple of "serious" PCP airguns, but these cheap & cheerful CO2 plinkers provide so much fun!
@@mottee Hi again Mottee, Thank you - your message made me think more carefully on the whole CO2 cylinder issue. I wanted to dig a bit deeper and try to fully understand what is happening to the cylinder during a shooting session. I have been in touch with an expert in this field and I have conducted some weighing and measuring research to get a bit knowledgeable. You are absolutely right to say that, in principle, the vapour pressure does not drop. However, as we know during real world shooting, when we are having big fun rapid firing and the cans are flying, the POI steps down with successive shots. This is due, as you said, to the temperature change in the cylinder as some of the liquid CO2 boils off to the vapour phase. As the cylinder warms up again the pressure rises to 57 BAR at 20C. In the UK we can count ourselves very lucky to enjoy a day with an air temperature of 20C. At lower ambient temperatures the cylinder pressure will be lower and during heatwaves it will be higher. We therefore need to check the POI at start of every day. In my testing and measurement of the Umarex brand CO2 cylinders I found that my batch contained on average 11.7g of CO2 in a cylinder volume of 15mL giving 780 kg/M3. So at 20 C the pressure will stabilise at 57 BAR but only until the CO2 content drops to 2.9g at which point it is all in the vapour phase. We then notice more extreme drops in the POI because from this point onwards the cylinder pressure will drop steadily with each shot even when the temperature remains constant. Again I think that this is something that we all recognise from real world shooting experience. So what can we do to alleviate this annoying POI shift? Well my tips would be to carry spare CO2 cylinders in your trouser pockets so that on cool days you can at least start the session with warm CO2. Try to shoot more slowly (difficult I know with a semi-auto and full mag of fun in your hand). If possible, for guns that have drop out cylinder holders, such as the MP-9 or the SA10, buy a spare a spare cylinder holder and keep it in your trouser pocket. Then after each 8-shot mag swap cylinder holders and let the other warm up in your trouser pocket. When I get some spare time I will do some more testing. I could try fitting a thermocouple to the cylinder and displaying the temperature while shooting over a chronograph. This should demonstrate and provide the data to confirm the temperature/muzzle energy relationship and the affect of rapid fire on the cylinder temp. Back to your original point about the low POI on your MP-9. I would suggest using very light pellets in all these CO2 guns. The Excite Econ II that I show in the video are only 7.5gr and dirt cheap to boot (£3.49 per 500 from JS Ramsbottom). They are well made consistent pellets and I highly recommend them. See my review of these bargain pellets - ruclips.net/video/669_SOr5UX0/видео.html Choose a warm day to test at the range. Next if the POI is still way too low then maybe carefully file the iron sights raise the elevation a tad. But for the best fun spend £23 on a reflex sight which will transform the gun's performance. All the best, Martin
Hi, Yes, this gun can be fired with either the left or right hand. The safety blade built into the trigger is a genuine safety feature that prevents the trigger from moving back far enough to fire the gun unless there is the tip of a finger pressing the blade inwards as the trigger is operated. It doesn't matter which finger. The safety button that slides through the gun sticks out on the left side of the gun when in the 'fire' position. So when firing the gun left handed it is possible for your trigger finger to press the safety to the 'safe' position (the thumb of your left hand would press the safety to the 'fire' position). But to be certain I have just had the gun out of its case to handle it in both hands and I can confirm that either hand is fine. All the best.
Hi, This MP-9 is manufactured by Gamo so I would have thought that the mag system would be proprietary to them so I'd be surprised if Sig mags would fit. Because the mags are so long even other Gamo stick mags won't fit it. Spare mags are available but I haven't felt the need to get any. I can however confirm that it is indeed sweet and real fun to shoot from the shoulder with the stock folded out. Tin cans hate it! Shooting 40mm spinners at 10M is simple enough. My grandkids found the trigger pull a bit heavy so they prefer the CP1. All the best.
Hi Cyrus, You are right the sight on the top rail is indeed a reflex sight. I have also had a laser sight on the lower rail of this gun and managed to mix up the names. Apologies. What I would add is that these sights are brilliant for the money. They offer a choice of red and green and 4 reticules - dot, ring, cross and combination. Only down side is they are a little big and heavy on a pistol (but look appropriate on a big heavy pistol like the CP1). I have 3 of these sights and another on order direct from China for under £14 - so no complaints on the price. All the best.
@@cyrusshellard3905 Yep. And talking of getting mugged off - I received a 3x44 Red Dot Reflex tube type sight today from China after waiting 2 months. It has turned up branded 'Luger' (ho ho). It is big and bulky but I wanted the 3x magnification for a CP2 setup as a rifle. The laugh is that I can't see any magnification at all and the sight picture is the same size but dimmer than the 1x40 sight (branded Bushnell ho ho). When I hold the 2 sights side by side I prefer the 1x40 but the dot size is huge and way too bright on the lowest setting. If anything I think that the '3x44' may actually be slightly shrinking the image as viewed by the naked eye (sort of 0.9 mag). The dot size is small but it appears like 2x touching dots due to internal reflections. In short it is a piece of ****. I may do a few videos on the red dot and laser sights that I have just to give people a warning about the quality and try to steer them towards the better types.
Hi, No it is not full auto. It is semi auto - each shot recocks the hammer and then the initial 'first stage' of the trigger pull rotates the mag to present the next pellet.
Thanks David Attenborough!
Lovely looking gun. Just ordered one. Can't wait! 😉👍
