I use my Glock 43. It is just a short off-duty type course with max distance of 15 yards with most of the strings fired and more realistic self defense distances.

Some time back (ooops another serious thread drift here) NYPD did a study of 6000 slf defense shootings over a ten year period of time. Virtually all were less than 21 ft and most were less than 10 ft with the majority less than that.

OK,now back to the scope issue
