I recently purchased a Walther P99 9mm for my girlfriend. I shot it Monday night and came away very impressed with its features, accuracy, and function. I am considering a Walther P99 .40 for me and would appreciate reports of reader's actual experiences with the Walther (not the SW) P99 in this caliber, particularly with respect to reliability, specific malfunctions, remedies, etc. With all due respect, this is not a request for arguments for/against Walther's vs. Sigs, Glocks, Steyrs, H&K's, 1911's, etc. I'm not debating the stopping power of the 9mm vs. a .40, .45. 10mm, or 50 BMG. Nor am I seeking info obtained second or third hand from discussion groups, gun rags, gunshop counters, etc., or a discussion of the merits of the P99's particular (and somewhat peculiar) features. I'm specifically looking for information about experiences with feeding or exraction problems, bulged brass, parts breaking, or the slide locking open prematurely. Actual experience from owners who have shot this pistol for more than 100 rounds or more would be very helpful. My decision process does not involve buying another brand/model in lieu of the Walther, but deciding if I want another 9mm or .40. I truly appreciate the experiences of this board. God bless.
