SA and Tall Novak Rear Sight

Anybody have an idea as to why Springfield uses a .375 tall rear sight instead of the standard ,325 tall rear? I have noticed this on my MC Operator and other “Loaded” models.

Just a WAG but many Springfield Armory owners complain that their pistols shoot low so they may be installing the tall rear sight to compensate for that.

Thanks Dave. By the way I just ordered yesterday an ignition set from you for my MC Operator.
