Question: does it need co2 to shoot?
Document: Do be careful because the grips lock/snap together with 2 narrow protrusions each of plastic on the inside of each grip. I used a partial drop of Pellgun oil on each when put back together and that helped considerably on the next removal times. You will need the oil for lubrication for the top of each co2 cartridge which helps maintain the seal in the pistol so you need to order that at the same time as well.
this is a great gun. feels real and looks real. shoots with in a 1/4 inch in1 15 feet.remember to get CO2 because it does not come with any . Great fun  This is not a toy  it is a gun  treat it as such. Like everone elso I know it leaks co2  so shoot up co2 in no less then 2 days
It was shipped on time and nicely packaged. I couldnt wait to shoot it. Everything came out of the packaging easily and all peices were there. Had co2 delivered the previous day, so I took my first shot. Much more realistic than i expected it to be, from the look to the feel to the loudness of it. Accuracy was great and pellets flew fast. Great gun overall. Thanks Crosman!
Got this for my birthday so I can go out and shoot with my kids and not disturb the neighbors. What a blast! Fires off ten rounds as fast as you want. We can hit a spin target at 20 yards! Plenty of power. Goes thru co2 quickly, but worth the fun. Buy plenty of co2 and pellets. Just ordered some of the hollowpoints! They'll be here Friday! Can't wait, there are many scared bottles in my back yard!
I checked numerous reviews before deciding on this purchase. First the shipping was quick and the item was well packaged. After unpacking, it was noted that the description and photos of the pistol are very accurate. It has a good weight to it and also easy to handle  and hold. I have fairly large hands and a small person or youth with small hands may fine it a littler harder to hold. The existing physical description is very accurate and doesn't need repeating here.
It was exactly what i was expecting, it shoot very good. I made some shots for fun and was very nice
This was the best purchase I have ever made. I would reccommend it to everyone. It's realistic, easy to shoot, and easy to reload.
i love this product it has a great life span on the co2 and it is one of the most accurate guns i have.
This gun is so amazing, no regrets in this purchase. Easy to insert co2 and easy to operate. Alot of power for a handgun!
I ordered this just for fun, i am a very active shooter with many different calibers. When i take my niece or nephew to the field to shoot BB's or pellet targets this is one of the pieces we take. It is VERY accurate out of the box which suprised me being a left handed shooter. i have made no changes to the rear sight (which is the only one u can change).
