Some advice for you to consider. Don't go over 2.5X on the magnification for hand holding. Scope maybe to large and any movement will be seem to make the cross hairs dance all over your target. A red dot seems to be faster onto the target than a scope, as eye alignment isn't as critical.(l to r, u and d) A scope will give you a bit more precision if only target shooting.( A red dot sights dot, will cover aprox. 1-2" at 50 yards) A red dot works great for either target shooting or game shooting out to most hand holdable distances. (30-50 yards) You do have to remember to turn on and off a red dot.. (batteries) I have had and shot both and prefer a red dot. Thats whats on my target pistol now (MP95E Benelli .22). Compare both at arms length, compare both cheap and more costly brands. Brands of scopes are pretty limited as to choices, red dots it seems everyone makes them. RD's range from about 40.00 to multiple 100.00's. The BSA on my Beeman air pistol was around 40-50.00, the Ultra Dot on my MP95E was aprox. 150-160.00. They both do very good jobs for what they are mounted on. Take your time in picking out what you want, thats part of the fun! But do get something thats nice and clear when you look through it, and seems to be well made. Get good mounts for it also, the best sight is worthless if it doesn't stay put..
Sorry about the long reply, just some things that I've found through the years.
Be safe, but have fun!
