I felt that the BP9CC was pretty well made. Field stripping it all the internals looked good, nicely machined with no burrs or excessive tool marks. It operates smoothly and is a good shooter. My sister ended up talking me out of it but I put a thousand trouble free rounds through it before she got it from me.
The pros of the gun:
1) Trigger- the trigger on the gun is great! Very light, almost shockingly light for a gun with no safety. But pretty clean, not spongy at all with a good break.
2) Size- the BP9CC is very very slim and light. I haven't compared it head to head with everything out there but it's very easy to conceal.
3) Shootability- it really points well and is easy to shoot. Recoil is subjectively very manageable and the gun is a soft shooter.
4) Ergonomics- this is subjective but it really fit my hand well; nice contours and the surfaces are 'melted' to minimize any sharp corners or hot spots.
The downsides as I see them:
1) Mags- no one but Bersa seems to make them and the best price I found was around $45 each! And to think I used to gripe that HK mags were expensive! They do seem work well though.
2) Internal lock- I never had any issues with it but just on principle I dislike internal locks. Just one more thing to fail.
3) Lack of holsters and accessories- I was able to find a few holsters but sadly Garrett Industries doesn't offer one. If I can't get a GI Silent Thunder IWB for a given gun I will probably not carry that gun much. It does use Sig and Glock sights so at least you can get alternate sights (night sights, etc) for it.
4) Sight regulation- the gun was accurate but it seemed that the sights weren't perfectly regulated, mine shot a bit low. However, you can get different height sights. And all I shot was 115gr. I owned during the Great Ammo Scare and couldn't put my hands on 9mm ammo easily so I didn't have any chance to try much besides Tul and WWB.
