Ron, I have a 181 series Mini that I am starting to accurize,with accessories and things talked about by cajungeo and some others.I was typically getting lousy groups at 100 yds. with std. ammo or reloads-didn't matter.Then I found this forum site and have started to turn around the gun,accuracy wise.Never had any reliability problems,though.Got that gun from a newspaper ad for $89.00 years ago,with 6 -20 rnd. mags and 200 rnds ammo.
