Don't you already have a Kimber switch-barrel pistol in .38 Super and 10mm? For range fun and just plinking around, try some of your .38 Super magazines in your new 9mm pistol. it won't hurt anything at all, and might even save some coin.
I have three of the Wilson ETMs, and a couple of the MecGar top-of-their-line 10 round magazines, all of which work well, but that extra round doesn't excite me that much. The MecGars came with my Stingray, the other two cheapo MecGars came with my Tank Commander, and I surely canNOT recommnend them.
Metalform used to have the contract with Colt to make magazines for them, so I figured they'd be okay, but they have weaknesses, as I mentioned earlier. I actually like the Springfield magazines about as much as anyone elses, including those high dollar ETMs.


You can roll a turd in peanuts, dip it in chocolate, and it still ain't no damn Baby Ruth.
