beat me to is
hmmm idk, maybe because nearly every police dept and acronym agency in the country carry them have proven time and time again that they are beyond reliable.I'm sure the "block" nuts are going to come from every and cranny in horrible indignation, but if "blocks" are do great, why are so many up for sale?? I have tried them and find no such fascination about them. Oh well, guess I am just " block snobbery" material.
Maybe it's their customer service.
Maybe people know you wont find a better pistol magazine for the price.
Maybe they like colorfilled polymer
Maybe it's the 15+1 round 10 mm that has set the bar
Either way I'm stumped
