Hi to all. New around here, novice with semi-auto handguns. Bought a Kimber .45 CDP Pro II new in Sept 2008. I clean/lube the gun "by the Kimber manual" every 150 rounds or so. Using 230 gr FMJ American Eagle and Blazer rounds (not +P) at the firing range, we had about 10% randomly timed misfeeds through first 500 rounds and chalked it up to "break-in". Now we're up to 800 rounds and we're still having misfeeds. Most common misfeed is when the next round doesn't seem to fully clear the top of the magazine, the bullet is tilted mildly downward and the slide stays back. A less common misfeed ends up with next round mid between magazine and chamber tilted upward. Misfeeds happen randomly throughout the magazine with no clear pattern. Two instructors say my form is decent and shouldn't be causing problems. Gun misfed a couple of times with an experienced instructor at the helm. Two local gunsmiths have tweaked the extractor (?) and have found no "problems". Have tried a few changes with following results:
- New 8 round Chip Mc magazine made no difference.
- New 24 lb recoil spring with Chip mag seemed to make problem much worse (although my aim seemed to improve markedly).
- New Wilson 8 round mag with 24 lb spring made very mild improvement over Chip Mc/24 lb combo.
- Going back to stock 22 lb spring (with about 600 rounds on it) with Wilson mag seemed to give the fewest misfeeds so far.
- Called Kimber, they said it was probably my shooting form, but that I could send it in for checkout.
Everything seems to suggest that the Wilson mag and a 20 lb spring might be a good combo to try. Does this sound "reasonable"? Any risk of damage due to reduced slide control? Anything I'm overlooking? Thanks for any help in advance!!
