i dont buy anything but Wilson anymore. i have a Chip and it is reliable 90% sometimes it shoots the bullet straight up into the top of the chamber and jams. but Wilson has always been 100%. i actually ran over a 10 rnd Wilson mag and bent the housing to crap. when i contacted Wilson to buy a replacement housing (spring,folower and base plate were still good) they told me to send in the whole thing and they will replace it for free. 2 weeks later i got a brand new 10 rnder in the mail no charge. they have my business for life now. great customer service goes a long way for me.
