I have 2x Colibri;s (hummingbird) & 2x 's Zbroia Kozak's, & 5 x's P-rods & a Impact(was Ernest Rowe's personal gun), also had a new Wildcat , sold it..all I shoot anymore are the Kozak's , by far the easiest to load , no double loading , also can remove mag at anytime to load & re insert ,IF I would have had the Kozak 's before all of the other s mentioned, I wouldn't have so may a/guns. & yes I have double loaded the P-rod's many times, it sucks..
