Couldn't find my RRA paperwork, but I beleve I had my RR guns in '98. In all fairness, I also had a two Wilson .45,s around the same time with warranty problems and I don,t want to risk confusing which guns had which problems. The main problem that I can defintely recall with the RR gun was that the feed ramp in the frame had been rounded over at the top, virtually eliminating the 1/32" space necessary between the rear position of the barrel ramp and the top front edge of the frame ramp. This is not a minor problem. I have owned previous 1911,s with this problem and they never fed as smoothly or reliabley as a properly fitted gun. RRA attempted to correct this by grinding the barrel ramp deeper, leaving even more case head unsupported. Fortunately the .45 ACP is a relatively low pressure round, but I did not consider this attempt at a quick fix acceptable on a semi-custom gun costing over $1000.00. As I said before,they warrantied the gun, so obviously they are a reputable outfit and I bear them no ill will. The replacement gun was better, but still not what I expected. By the way, Kuuhnhausen's "THE COLT .45 AUTOMATIC" has an excellent discussion of this problem starting on page 65.
