I bought a 22/45 lite in july due to a strong need of a 22lr pistol, everyone else in my family owns the 22/45 standard and I actually prefer the standard to tell you the truth. the sight radius is shorter on the lites and it seems like accuracy slips with a hot barrel while the standards don't seem to have that problem.
however the threaded barrel is a nice thing to have, I need to get my tax stamp so I can start to have some super quiet fun
