My 1911 is finished and complete. It usually fires relaiably but the other % of the time the .45's dont quite feed up the ramp properly obviously causing a jam. I know why and its because there is about .50-.75 (maybe) 1000th's of an inch play in the magazine...The catch doesnt quite hold the mag perfectly tight. Is this common in 1911's? Should I shop around and try different mags? is there some modifications I can do to the mag catch? Is there a barrel out there that has an extended feed ramp someone might recommend? hmmm...besides that-anyone who ever thought cutting the rails for a 1911 whould be too hard to do without expensive machine equipment-think again and read what co7t has to say about the dremel method. I used like, 6 cutting disks maybe alltogether. and it took me maybe 4 or 5 hours-wouldve been less if i wasnt dickin around all the time tring to keep my dog from barking when i would start up the dremel.
