yes plan to loctite steel shims in place. have not fired these gun with the paper shims yet. had not considered aluminum duct tape as i considered it too soft material that would not take much battering. used paper shims to see if the barrels could be brought back on face and the latch lever would be well right of center. the thickness of the paper shims can be accurately measured to cut a metal shim or turn a replacement pin for replacement. was thinking the steel shim would be a long lasting fix if used with low pressure target loads. i am not a machinist and have not located a competent gunsmith to install new pins in these shotguns. just wanted a good temporary fix. i consider the lefever nitro's the best made "cheap" usa made double sold before ww 2 and worth doing s proper repair fix eventually.
