My own Hi-Power isn't a very good CCW gun at the moment; getting double feeds. I think my extractor spring was damaged. I haven't had a chance to get it looked at yet. But I did carry it for 20 years or so. Once it's running right again I will probably add it back into the rotation, but as much as it pains me to say it I think the BHP has kind of had it's day. Don't get me wrong, it's a classic. But I think as a service/carry gun it's probably been surpassed. My HK P30S is probably a better gun by any objective measure, and with the Gray Guns trigger it's at least as good a trigger as the BHP, maybe a little better. The safety is larger and more positive, it holds more rounds and is at least as accurate, maybe more so. The only edge I'd give the BHP is concealability; it's as wide in the grip but very narrow through the frame and slide. It does disappear a little more easily than the P30S. And realistically the VP9 is about as good as the P30S, some would probably prefer it.
I haven't ever shot a Shield but it's very close to ideal, size-wise. I don't care much for the trigger, but realistically it's plenty good for what it is. The Bersa BP9CC is another one that's very slim and easy to carry. Mine shot pretty well but it much higher than POA. I didn't have it long enough to change the sights (my sister liked the gun and talked me out of it). It doesn't have much track record good or bad. It ran well for me, no bobbles in the 1,000 rounds I put through it. The internal lock is a minus in my eyes and the mags are $48 each (couldn't find 'em any cheaper). The trigger was light to the point of giving me the heebie jeebies carrying it but as always, protect the trigger. The biggest hurdle to using it as a CCW gun is that my favorite holster maker doesn't offer a rig for it. Still, if it holds up to heavy use over time it might be on that short list.
I truly wish I liked Glocks! It would make my life easier. Sadly they have never "stuck" to me. I truly loathed my G22 and was glad to be rid of it. The G19 is a very good size and form factor for CCW but I can't stand the trigger and really don't find it to be a good shooter in my hand. But I can see how it would be close to ideal for many people. If they made the exact same gun but thinner in a single stack- I guess it would be a Bersa BP9CC!
The Walther PPS is one of the most promising guns out there that I've not had a chance to try. None of the stores around me have one. The reviews are stellar though and it seems like the perfect size.
The Ruger LCPs is another one that has me intrigued. I've only fondled them in the store, not fired one, but the trigger is as good as I can imagine finding in a striker gun. Nearly as good as my VP9! I'm not enthused about the safety on the gun. I wish it could be had w/o one, or at a minimum I wish it was larger and more positive. But it's soooo thin and light that I think I will probably try one. It could possibly supplant my Beretta Nano.
I have high hopes for the HK P30sk! Not sure when it will actually come out. HK takes their time on new releases, it may be a year. When it does come out I'm gonna be very stoked to try one. It might also replace my Nano for situations when I can't conceal a larger gun.
