Things I liked:I found this pistol to be very easy to charge the co2's and load pellets.I did not use bb's.I did find the safety worked easy on this and my Walther CompactCP99.Most of my shooting has been in 10 to 30 degree temps.Can't wait for 70's. Things I would have changed:I think adjustable rear sights would improve accuracy a great deal.I added a Center Point laser/flashlight combo and accuracy greatly improved. What others should know:I did find it very picky with pellet brands,Crosman HP's,Hp's and Destroyers worked extremely well.Daisy wadcutters were too loose.
Things I liked:Worked as advertised.I used these in my S&W M&P 45.No problems whatsoever. Things I would have changed:I can't think of anything. What others should know:I did find that Daisy wadcutters would not stay even when seated.
