4.5-5 lb model has different shoe - Wilson Combat AR-15 Tactical Trigger Unit

the wc ttu’s are always crisp and easy to install but the last model i got, the heavy duty 4.5-5 lb version has a different trigger shoe than all the rest. it is wider and not beveled like the other models, so if your finger is anywhere need the lower portion it actually feels sharp and can hurt if not wearing gloves. disappointing because other than that its great.
