The thought of it is sickening. I've got a Glock 32 that came with two 10 round mags during the stupid pointless 94-2004 AWB. Also have a Glock 35 that I bought off GB which was CA compliant and came with 10 round mags. There is no way I'd carry either of those pistols with a 10 round mag. Glock 26/27/33/29SF/30SF or a 1911 in 9mm, 10mm, 45 acp - plenty of options originally designed for 10 rounds or less. A 1911 conceals easily IWB, mercifully pictured with a t-shirt, just add cover shirt (in warm weather I wear an a-frame / thin tank under a cover shirt).
