When I waa still on the job I carried a G17 magazine as a reload for my G26. 70% more ammo for just a bit more length which didn't interfere with concealability.
I figured if I didn't settle the problem with 11 rds I could use as much ammo in my pistol as possible. Never has a problem using G19,G17, or even the 30+ rd G18 magazine with or without the sleeve.
Glock 19 Gen 4. This one has about 750rds through it and is in like new condition. No scratches or blemishes. Comes with original case and all contents minus the cleaning brush. 3-10rd mags replaced the 15rd mags because NJ. I am in North NJ near Morristown. I will travel to your preferred FFL within a reasonable distance from me to do the transfer. You pay all transfer fees, taxes, etc.
Sale is cash only.
Just picked these up. Seem well made and comfortable to wear. I will be trying these and the neomag, which I already had.
Also, wondering if other folks have heard this. I learned (don't remember where) that if you are carrying a subcompact that should carry a full-size (and legal capacity for your AO) spare mag. Basically the reasoning is that for subcompact mags you need to flare out your palm a bit when inserting the mag and during fan/crap scenario you may well pinch the side of your hand trying to insert the spare mag. A longer mag does not have this problem. And in free states, it holds more food!
