GREAT TOPIC!....this is more than a cosmetic problem....this is the kind of thing that gives taurus the "cheap, low quality gun reputation"...and as a big-time taurus fan, i find it completely unacceptable.
i've experienced this "mag doesn't fit right" problem on my .40 s&w model 24/7 pistol, and i've also seen this problem on several .40 & .45 models in 4 different stores. yeah, my .40 never missed a beat, but this problem was the reason i traded it for a s&w m&p .40. the m&p has no such problem.
i belive this is a mag production issue. i believe the cut in the mag for the mag catch is the issue. simple design engineering, manufacturing tolerances, and quality control. i really like the 24/7 pistols, but other mfg's don't have this problem. i checked for this very problem on other brand of guns before deciding to ditch my .40 24/7 pistol. who's guns don't have this problem?....well, for starters, i can tell you the following had perfectly fitting magazines: CZ, S&W, FN, H&K, Sig, Glock, XD, and several others. CZ, S&W, and FN are my favorites, but fact is i could not find this problem on any other pistol i checked----and i checked-out a lot of guns! i've purchased two CZ's and two M&P's this year. some of these sales would have gone to taurus, if they didn't have this problem.
GOOD NEWS: i also have a 9mm 24/7 longslide with mags that fit almost perfectly. i've also seen other 24/7 9mm pistols in several stores that did not have this problem (4" and 13 round compact models included). were the 9mm mags designed or built better than the other calibers? is this just a coincidence, or did taurus get it right on the 9mm?
this is the #1 thing i will check before buying an OSS pistol....if they ever actually ship the OSS models....and i really do want one.
bottom line....i've shot a total of 10k rounds thru my 24/7 pisols, and i love them. but if you can't make a quality product, you're not competitive, and i'll spend my money with a mfg that is.
