I apologize in advance for any breech of forum etiquette I thought my question was a simple one but I am not seeing any direct answer. First let me be clear about the caliber, I am speaking to the 380 only. The Gun I am looking for is the Performance Center M&P 380 Shield EZ 380. It seem there is a M.20 vs a Non M.2.0 Not new to guns but am new more or less to S&W I only own 1 S&W which is about 35 yrs old. A little 2214 22.cal Anyway a little clarity before I purchases would be helpful, as availability and prices seem to vary and I don't want to see a price that too good to be true but turns out not to have a desired feature. Yes I do want Thumb safety Thanks.
