Out of the 8 rounds tops it can hold that is still 3 less than I'd like that mag/weapon to carry. That's about how many it will take to get me semi-proficient on my slightly used but very well maintained new pistol.
So let me bitch about it 1st, with a $6 difference in a Walther © 7-round magazines which seems to be as good, maybe even better/newer & less costly (D-spring and other compounds added to the mag during the metal-mixing phase, like carbon heat absorbing chemicals), which the Walther brand mags lacks, but the MecGar © brand have, so I bought 5 of them online, legal & reputable $21.47 ea a day after buying the Walther as the best CCW in the best condition for $350 (cheaper than most I found new) that came with an 'Uncle Mikes' clip-on holster and 5 full boxes of American Eagle by Federal 95g FMJ. 40cal Centurion that is just too big for year round legal CCW carry, out of sight in WA. 22 pellet guns (CO2), an authentic 1940 Luger, minus the legalizing import papers :-(, (War trophy) many large mid and small semi-autos, so I asked my passed-on friend's eldest son which one his dad always took with him as his CCW of choice, and up came a Walther PPK/S1, it was just (IMHO) the best made larger cal than my Springfield XD-9mm CCW weapon of that beat out the others for my needs, just small enough for complete concealed carry year-round but nowhere a large as my Beretta 96 FS.
No! It wasn't me trying to emulate any 007 flick! There were 23 weapons laid out for grabs in an estate sale, many large revolvers, a few shotguns, rifles, hi-powered. I recently came into possession of a Walther PPK/S1.
