Things I liked:PROs: Solid feel. Good looks. Nice trigger pull. Great accuracy. Things I would have changed:CONs: A bit difficult to insert pellet unless you have very small fingers. Somewhat difficult to cock. What others should know:So far my P17 has been working perfectly with approximately 1000 pellets through it so far. I would like to mention that after the pellet has been inserted into the tube it must be pushed in about a quarter of an inch to lock it into place. If you are fortunate enough to get one that is trouble free, it is an excellent target pistol, especially for the price
Things I liked:Well built, easy to cock, nice trigger pull, good sights. Things I would have changed:Requires a slight break in (not a big deal) and also a bit of getting used to if you aren't familiar with spring-piston air guns. What others should know:Mine likes the standard Crosman premium points and wadcutters.
This gun is big and heavy but yet is well balanced. It's a ball to shoot, so have a lot of pellets handy. Also, it's a great value at Pyramyd Air's price of $66.00.
Things I liked:Extremely good value for the price. Shooting good groups after only about 50 shots. Things I would have changed:Rear sight notch could be just a tad wider for us shooters with older eyes, but still acceptable. What others should know:Other reviewers have suggested using a dremel tool on the breech; however, I wouldn't bother - just find something to push the pellet in about 1/8". I use a piece of scrap plastic from a model car kit. My friend uses an Allen wrench. This seats the pellet perfectly and will give you the correct back pressure.
Penetration: Using a piece of 1/4" plywood and Gamo Master Point pellets the X5 is about equal to my Crosman American Classic pistol and my Crosman 760 rifle (with each at 10 pumps) or my Crosman 1077 rifle with a fresh CO2 cartridge. Not bad at all for a break-barrel rifle that cocks this easily.
