Hiya CCWLearner and thx for your thread. Have not tried those on my cz's but extra careful with the ones that have no rubber or plastic on the base. The cost of almost 19 bucks sounds a smidge over valued. Take a peek over at Greg Cotes site for the ones avail for your p-07. I do lean towards bases that facilitate a few extra rounds,of course only if ones state allows. Here in arid zona don't think its limited. If ya have more than 25posts up consider WTB p-07 rubber/poly base plate in the wanted ads. Cheers. Be well.
