Fuck locktite. If you dont want it to unthread, use JB weld.
If you want the most bang for your buck, i'm going to voiolate one of my normal gun rules "Dont Buy a Gun Made In a Country You Wouldnt Drink the Water In" (Unless, of course, its a AK version. The only shitty one i've ever seen was a Port Said.)
Check out the Tarus 1911.
http://www.taurususa.com/product-detail ... ory=pistolI've handled a few, and they lock up just fine, and seem to have pretty good fit and finish. I havent shot one, but frankly, all 1911 pistols shoot pretty damn simmilar untill you run over 500 rounds through it.
The best mags are either Chip Mccormic Shooting Star or Wilson Combat mags. Never had any problems with 'em, and I found and used some Chip Mccormic mags I left loaded for like two years, and they still fed okay. They must have some DAMN good springs.
