Your solution is the Burris 3-12 x 32mm hand gun scope. Plenty of magnification for 200 yards. It's the highest power LER scope I know of. Has 1" tube so should work perfectly. Has good reviews too. Here's a link to check it out

Burris isnt the best there is, but they're solid. And they have an 'unconditional, no questions asked' lifetime warranty. I had an old Signature series scope years ago and it had trouble when I accidentally 'threw' it on the ground following a missed shot on a bear :

Told them what was wrong, they didnt ask what happened, sent it in, and they fixed it without a word. Lost scope caps 2 times over the years too. Called them and they put them in the mail right away, free of charge. Although I purchase higher end optics nowadays, (***Burris glass is very nice though) I will always look positively on Burris because of their outstanding customer service.
