This is how "thick and bulky" the double-stack M13 and M10 are... about same as the best selling pistol in the world (with a GLOCK 19) The single stack PSP and M8 are noticeably thinner in the grip than all the common double-stack pistols (GLOCK, Beretta 92, SIG 226, etc.).
The more modern double-stack HK pistols like the USP and P2000 are similar to the M13/M10 in grip thickness. The USP is the biggest feeling pistol of this group:
L to R: M13, M8, PSP, P9, USP, P2000
And these are close-ups of the of the M13, M8 and PSP. The M13/M10 mainly just look fat because the barrel sits further back in the design of the gun, making the "butt to muzzle" ratio of the gun a lot different from most designs. The thickness is right on par with almost every other double-stack design.
I like the feel of the double-stack M13 more than any other pistol. Everyone's hands are a bit different, but to say that it is so big a bulky as to be unusable (as someone always does with these pistols are discussed) is simply incorrect and ridiculous:
Single-stack and double-stack. This is an M13 mag and an M8 mag. The M13 and M10 mags are a little bit different (in the lips and the follower), but the M10 mags work fine with the 9mm pistol, making it a legal 13 round pistol (if you can find/afford the expensive and rare M10 mags.. which gets a little harder every year for new people getting into it):
A 1992 M10 with a 1975 HK P9S:
A 1992 M10 with a 1982 Steyr GB (which is a similar-sized pistol to a Beretta 92, actually slightly bigger):
A high-end self-defence kit? Just break glass and go
Some holster options:
German police holster. Back in the days before Safariland rotating hoods, they had this kind of double-locking system. The user unlocks the bottom snap, the upward movement of the pistol unlocks the other one. It works surprisingly well:
