The XP-270 is the replacement for the XP-70. The XP-270 boasts 25% more water then the XP-70. The XP-270 is fairly sturdy and does not take to many pumps to charge. After comparing both the XP-70 and the 270 they perform the same except that the 270 has alot more water. The 270 is one of the smallest weapons to feature a seperate compression chamber, which also means that it doesn't take alot of pumpms to charge. The XP-270 has a strange pump which can be annoying sometimes. Basically the XP-270 is a great backup or sidearm that will still be in production for 2001 Pros:light and performs good,seperate compression chamber Cons:bright colors, and small shot times RATING:6.5/10
