I just got my hands on two new production Tapco Gen II magazines. They work perfectly and are not loose and or too tight a fit in my 581 Tactical.
Lucky for me I live 20 minutes from Tapco here in Georgia. I called them and stated my older Gen II mags were too tight for my 581. They said come on by and they would swap out no charge for new production mags. I was at their office for less than 10 minutes. I love Tapco. I went to the range and cycled fully loaded mags with no FTF issues. To conserve ammo I only fired three rounds each from fully loaded (30) round mags. The first three rounds functioned no problem. I did this several times to each mag. I then took both mags and only loaded 3 rounds and fired to test for the bolt locking to the rear and also if the last three rounds would fire without FTF issues. Both mags worked as designed. Who can afford to burn through 30 rounds to test a magazine these days? I was using 55 grain PMC Bronze ammo and also American Eagle 55 grain. I did notice that Fiochi V Max is too long to load in these mags. I have some USGI 62 grain green tip and these loaded and ejected manually. Didn't want to shoot my preper ammo. I also was able to load Fusion 62 grain. So I would say the Tapco can handle some 62 grain but V-max bullets look too long. 55 grain FMJ is probably the best ammo for the Tapco mags. I like these new mags. Tapco said these aren't Gen III they are just called newer prodcution Gen II magazines. Looks like they took off a bit of the thickness off the top rear of the mag. So now I have more of the dreaded and evil hi-cap mags.
