the LT 20 is lighter so is better for a lady. everyone has seen the full size 1100's not work all the time. I have been shooting the LT 20 for 3 yr's. & have had no failures. Mag. ext.'s are made for them. 9 rd. side saddles, & with a dead mule recoil reducer & a decellarater pad it is like shooting a 10/22
