Question: can you attach a laser light or flashlight to this gun
Document: Realistic feel, solid and very well constructed. My son loves the gun, it shoots close groups at 10 yards out of the box.
It is a really nice looking gun. Buy extra magazines even though they are expensive but they are of good quality and should last for some time. I recommend this gun.
Be sure not to fire the gun even if it is unloaded. A stuck pellet could be expelled by the air from a CO2 cylinder and do harm. Used properly these guns will give hours of fun.
My man loves this gun he said its feels great fires good he can hit a soda can from like 75' without a prob. he is now looking to get the real walther ppq 40. s/w
If your shooting this gun in winter make sure you don't go trigger happy and use the semi automatic feature too fast or else it will stall. Over all the gun is great, it's not too heavy so it has a nice feel. It's also really accurate. (This is written by my son.. --WN Burnett)
The powerlet and clip are easy to load, and the c02 will last a long time too. Looks and feels very real, an amazing replica. I think the gun has a pretty short grip, and will fit smaller hands very comfortably. I recommend for beginners as well as serious airgun junkies, a very nice gun overall.
I wanna BB gun... I wanna Pellet gun... Oh no! What do I do?Well, ladies and gentlemen, you need not agonize any longer as Umarex have anticipated this conundrum and provided the solution.The Walther PPQ. Great weight in the hand, authentically approximating the actual bullet firing firearm, it is a delight to admire, hold and importantly shoot.
You should check into the laws before purchasing. Do not conceal them, and if you do travel with them leave them unloaded, safety on, and breach open. In some states, guns and ammunition must be stored separately, in locked containers. These air guns are not toys. Make sure you have a proper backstop when shooting and know what you are shooting at. Never point a gun, even an air gun at anyone loaded or unloaded. It is just a good safety practice.
The gun is hefty, about 1.3 lbs of abs plastic and a metal barrel. Non-blowback, but has a slide lever button, and a similar safety lever on the right side. I am a little dissappointed in the plastic trigger, but other than that, this is a durable airgun. This shoots 360 fps with fresh c02 according to the package, but I think it was shooting a bit lower for me, kind of a let down.
This is my first co2 airgun of any kind. I bought it to keep my shooting skills crisp because I can't get to the range with my real weapon as much as i would like. I am VERY impressed by the accuracy of the gun after I adjusted the rear sight and got used to it's trigger pull. Have been shooting it inside my apt (12'+) into a target i made from the amazon box. Wouldn't advise this unless your a very good to great shot!!!!
