A few years ago I sold off my pre-ban Colt Sporter Lwt. in 9mm, and have regretted it ever since. At the time I sold it, I had two 9mm carbines, the Colt and an UZI Model B. Lately I've been thinking about selling the UZI to replace the Colt 9, but would like to hear a few opinions first. Should I keep the UZI and just be happy with my two Colt carbines in 5.56, or dump the UZI and go to an all Colt weapons system ?? From what I've been able to discern, the UZI 9mm Carbines are perhaps the most reliable & accurate of the breed. If I go for the Colt 9, I'll pick up a complete upper & related components. That should probably run me about $800 or so, give or take a few either way. Are the Colt 9mm "drop in" magazine adapter / blocks very reliable, I've heard different opinions regarding their function ? I really do prefer the feel of the Colt 9 over the UZI, and the Colt is also much lighter. ( I still have 4 brand new Colt 9mm factory 32 rd mags. If I decide to keep the UZI, I'll probably sell or swap them towards a nice Red-Dot optic for my Colt 6721.) I guess my question boils down to which is the better weapon, a Colt 9 or an UZI Model B ? PLEASE HELP Guys, I could really use some opinions right now. (P.S.: SORRY for the slightly long post.) THANK YOU. Regards, Dom Pastore
