Question: Is it a single action or double action ?
Document: I like everything about this beauty. Nice weight on it, looks amazing. Nice blow back, aggressive, fast and soft trigger. Single action only. It locks back when the magazine is empty. It's a bit uncomfortable to load the co2 but other than that is perfect. I paid around $80 for this one, no other better and nicer gun at that price range. Very, very, very nice gun, definitely recommended.
what great service! real guns..rarely give  15.000 rounds of service perfect to the end..when it died the slide..came back so far..i thought it might hit me.. but it stopped..Buy another/ ones on order already.. i shoot everday and i have four clips and laser..so no brainer..read my tips perhaps you will be so lucky!
this is an awesome piece id buy this item again if need it be.. it feels like real deal its a definite recommendation for those who like the realistic feel.. i love it.. everything works great
this gun have some problems. i want my money back or a new gun i dont know pla contact me by email and i will explain youcharlie2020@hotmail.es
heavy duty compressed air gun. Shoot bbs about 70 per CO2 tank. The only thing is the pain is installing CO2 because you have to twist the bottom. by the other excellent speed and accuracy
gives it a realism , few can match.. it recoils a lot like a ww2 .32 acp walther pp, in the family.. not to hard, but you can get slide bite, if not held well..sights are spot on, using daisy silvers. not coppers , they can corrode.. bought 2 extra mags, and then I bought the laser.
This air bb pistol is really good, among all the reviews and technicalities given to it and comprising with others, this one makes a defenetly a &#34;most buy&#34; price is right and the product is a high quality, one of the best products Umarex have.
The recoil has also decreased along with tightness of parts (slide cycles easier as paint is worn off on guides) Recoil is great for a BB gun expect 1/4 that of a 9mm for first round and decrease as Co2 empties and gun gets cold.If you are still not convinced this is a good enough pistol to practice with I don't know what else to tell you.
The idea that a BB Gun carries with it severe criminal liability seems ridiculous, yet after googling it, I found it's a major offense to shoot a BB gun in my city. For me that means taking it out of the city to shoot, but just be smart.All that said, it's super fun.
The attention to detail is fantastic. Looks like the p99. Weight is good, and its very well made. Nice blowback. Locks back when magazine is empty like the real thing. Shoots great. Cant say enough positive things about this little beauty. Its a great product and definitely worth the money. Its fun to shoot. The safety is a bit over done, and often requires two hands to release. I wish it would have came with an extra clip. I would definitely recommend this product!
Answer: yes
