SIG SAUER 12 Round 9mm Luger Magazine for Sig P365/P365XL/P365X, Extended, Coyote Brown, Steel

The magazine itself is nice and durable. The problem with these 12 round magazines with the extensions are that the plastic extension itself is so sloppy on the magazine. It causes issues when shooting. It is very irritating. They need to tighten it up to where it fits nice and snug at the base of the magazine and doesn’t move around at all. I have to actually add tape to it on the inside to get it to fit that way. Not a good thing.

Need more ammo and grip? Well go ahead and get this magazine.

The plastic base of the magazine is very loose and rattles. Does not have a secure feel.

This is the second identical SIG 12 round magazine I have purchased, and unfortunately, both have the same serious problem. When I had trouble with the first magazine, I assumed it was defective and bought another one. The second magazine was purchased approximately a year later, yet it consistently malfunctions in exactly the same way. Typically around the fourth to sixth round, a cartridge becomes stuck inside the magazine and fails to rise into feeding position. If you test this magazine only with round nose FMJ ammunition, you may get lucky and never notice the problem. I strongly recommend testing it with the defensive hollow point ammunition you actually carry. Both of my magazines jam consistently with hollow points and have occasionally done the same with FMJ ammunition. I use these 12 round magazines in a 365XL because they fit flush with the grip. I also use Sig 17 round Macro magazines, which appear to be constructed differently, and none of those have given me this problem. I love Sig products and have never had problems with any of them. A malfunction at the range is frustrating, but this is for everyday carry. Mine or my family’s safety could depend on it, and after having the same problem with two magazines, I’m seriously concerned whether I can trust it to do its job when it matters.
